Regional Financial Development and Regional Economic Growth: An Empirical Analysis of Suzhou City, China

There are many defects in researches on the relationship of the regional financial development (FD) and economic growth of China, such as simply assuming the causality direction, not highlighting financial institution, using incomplete financial indicator, etc. This article, taking Suzhou City of Jiangsu Province, China as a case, builds a simple model to study the level of FD from three aspects of financial scale, structure and institution. Three original indicators of PRIVY (private investment/aggregate investment), DEPTH (aggregate loan/GDP) and FDIVG (FDI/GDP) are used to construct the FD economic indicator through Principal Component Analysis approach. Then we use Granger method to analyze the relationship between the FD and the economic growth of Suzhou. Empirical test results show that the FD of Suzhou is the Granger reason of economic growth, while economic growth is not the reason for FD, because the relationship between the FD and the economic growth of Suzhou is just in the ″supply-leading″ period. In terms of Suzhou experiences, the local government should strengthen the protection of private investment, improve the institutional environment, and establish the reasonable financial structure. So we can concluded that FD could play a great role in promoting economic growth at the economy takeoff stage.

Exploring Regional Innovation Growth Through A Network Approach:A Case Study of the Yangtze River Delta Region,China

As the leading urban agglomeration in China,the Yangtze River Delta(YRD)is experiencing a factor-driven to innovationdriven transition.However,the dynamics of regional innovation growth are not yet fully understood.This paper combines the complex network methodology with spatial econometrics to disentangle the contributions of innovation endowments,innovation network flows,and innovation network positions to regional innovation growth,as well as their spatial spillover effects.The primary findings suggest that regional innovation growth results from the networked agglomeration economies,which is shaped by the interactions between agglomeration factors and network factors.Specifically,agglomeration factors play a fundamental role in regional innovation growth.In contrast,network factors,such as the network flows and network positions,may contribute to new path creation by promoting access to external innovation resources.Additionally,the institutional factors show multiplexity in fostering regional innovation patterns.Such findings indicate that the YRD region should shift the innovation growth pattern from competitive involution to mutually beneficial cooperation to reduce regional disparities.In this regard,the institutional capacity of organizing network flows and fostering reciprocal inter-city partnerships has become increasingly critical for promoting sustainable innovation and regional development.

Research on the correlation between regional economic growth and culture industry of our nation

For a nation, culture is not only the promotion and enhancement to the national spirit and the realm of life, but also an essential content and indispensable support force to achieve economic development, it is the important cause and prominent of the overall strength and the main carrier and specific embodiment of a nation＇s ＂soft power＂, besides, it also represents the degree of civilization, level of development and height of this nation. Culture and cultural industry endow with the modern culture with new meaning, it requires that at the time we achieve the prosperity and development of culture, we must actively explore and operate a scientific mechanism which is most able to release the energy of the culture and play cultural efficiency, and then develop the industrial pathway of the cultural. Cultural industry is a little different from the general industry. This causes the special natm-e of the cultural industry which is different from other industries. Different water and soil raised different people, inheriting national culture and developing cultural industry can be described as the unity of the three ones.

Empirical Study on Effect of Industrial Structure Change on Regional Economic Growth of Beijing-Tianjin-Hebei Metropolitan Region

Based on the data of gross domestic product(GDP),industrial added value and the proportion of industrial employees from 2000 to 2008,this paper studies the effect of industrial structure change on the regional economic growth of Beijing-Tianjin-Hebei Metropolitan Region in China using the shift-share method.The results show that:1) In the 21st century,the industrial output of three industries,namely,primary,secondary,and tertiary,and the GDP grew rapidly in the study period.The tertiary industry grew the fastest;it had the largest contribution to the GDP and mean-while had become the most competitive industry in the metropolitan region.2) The development of cities within the region was not balanced.Firstly,compared with Tianjin,Beijing,as one of the two core cities,was more rational in the industrial structure.Secondly,the surrounding eight cities,which are Shijiazhuang,Qinhuangdao,Tangshan,Langfang,Baoding,Cangzhou,Zhangjiakou,and Chengde,were all uncompetitive than the two core cities.3) There was a great industrial gradient in the region(especially between the two core cities and the cities of Tangshan,Baoding,Zhangjia-kou,Chengde,Cangzhou,and Langfang).As a result,it is foreseeable that the industry transfer in the Bei-jing-Tianjin-Hebei Metropolitan Region will be one of the trends in regional development,and the industry transfer is inevitably to promote the regional integration.

Efects of Crop Growth on Hydrological Processes in River Basins and on Regional Climate in China

The regional climate model RegCM3 incorporating the crop model CERES,called the RegCM3CERES model,was used to study the efects of crop growth and development on regional climate and hydrological processes over seven river basins in China.A 20-year numerical simulation showed that incorporating the crop growth and development processes improved the simulation of precipitation over the Haihe River Basin,Songhuajiang River Basin and Pearl River Basin.When compared with the RegCM3 control run,RegCM3CERES reduced the negative biases of monthly mean temperature over most of the seven basins in summer,especially the Haihe River Basin and Huaihe River Basin.The simulated maximum monthly evapotranspiration for summer(JJA)was around 100 mm in the basins of the Yangtze,Haihe,Huaihe and Pearl Rivers.The seasonal and annual variations of water balance components(runof,evapotranspiration and total precipitation)over all seven basins indicate that changes of evapotranspiration agree well with total precipitation.Compared to the RegCM3,RegCM3CERES simulations indicate reduced local water recycling rate over most of the seven basins due to lower evapotranspiration and greater water flux into these basins and an increased precipitation in the Heihe River Basin and Yellow River Basin,but reduced precipitation in the other five basins.Furthermore,a lower summer leaf area index(1.20 m2m 2),greater root soil moisture(0.01 m3m 3),lower latent heat flux(1.34 W m 2),and greater sensible heat flux(2.04 W m 2)are simulated for the Yangtze River Basin.

Changes of population growth in Tibet Autonomous Region

The population of the Tibet Autonomous Region which is thinly scattered, is almost entirely Tibetan. The unique high and cold climate, varied and changeable topography and social economic and human environment restrict population mobility in the region. Historically there were little statistic documents and the early data about population scale is poorly reliable. After the peaceful liberation of Tibet in 1951, its population went up continuously, and the growth rate has been higher than the national average level since 1964. The general tendency was that the pattern of population increase had changed within a short period. At first, the death rate was lowered quickly and the natural population increase speed was quickened, then, the death rate was lowered further, and the birth rate began to rise at a quick speed. After 1970, both the death rate and birth rate was generally stable, the level was relatively lower than before, the death rate slowed down at a quicker speed than the birth rate. The natural population increase rate rose extremely slowly, which formed the population development situation of fast but steady increase. The future population development tendency is that, the quick increase tendency characterized by young population will continue for quite a long time, and the pressure of future population increase upon resources environment will become increasingly great. The age structure and sex composition of population in Tibet, rather low since long time ago, became increasingly high upon entering the 1980s, but it was still the lowest one compared to other provinces or regions in China. The main reason is due to the low sex ratio of Tibetan infants and children caused by the low sex ratio of newly born infants and the high death rate of male infants, which will slow down the population increase in a limited way. There are few barren lands appropriate for farming and there exist many restricting factors for cultivation or utilization. With further increase in Tibetan population, it is inevitable that per capita available cultivated land will drop continuously. The problem of food supply in Tibet will still be the main issue in its regional development with the increase of population. It is impossible to support a quickly increasing population with the limited agricultural resources in Tibet. Therefore, the population development direction of Tibet can only be to tighten quantity control and to popularize family planning knowledge among Tibetan people. It is a fundamental strategic policy for the social and economic development in Tibet if family planning can be followed progressively on a voluntary basis.

The Spatial Spillover Effect of Input and Output of Scientific Progress on Regional Economic Growth: The Case of Guangdong Province

This paper makes an empirical analysis of the spatial spillover effect of regional economic growth by using Moran’s I and Spatial Durbin Model to study the input and output of technological progress, with the panel data of 21 prefecture-level cities in Guangdong Province from 2008 to 2017. The empirical results show that the spatial autocorrelation exists in the economic development of Guangdong Province, and both the input and output of scientific research innovation have a significant positive effect on the regional economic growth. Under the spatial contiguity weights matrix, the output of scientific research and innovation has a more obvious spillover effect on the economic growth of neighboring cities than the input of scientific research and innovation.

Financial and Structural Stimuli for Regional Growth

The economies during the post-industrial era are returning to the classical meaning of manufacturing sector in the process of balanced regional growth and are searching for stimuli for diversifying economic structure and reindustrialization. Expansion of a new growth theory highlighted the necessity for the well-developed so-called innovative manufacturing sector; however, stimuli for realizing the potential of this sector are limited due to relative attractiveness of sectors with lower risks and faster returns especially in regions followers. Moreover, regional success as a result of the previous development can hinder changes and stimulate economic agents to avoid regions and sectors with high potential but weak performance. Generation of regional economic growth can be considered in a framework of two kinds of stimuli as financial and structural. Financial capital as an important factor for supporting structural change in economy helps to stay in harmony with the modern economy; however, existing sectoral composition can be persistent to changes. Latvia is considered as a case study about issues on fmancial and structural stimuli for regional growth because of the bright dominance of capital city region （high regional differentiation） and typical post-industrial economic structure in parallel with an intention to actively participate in reindustrialization and increase the innovativeness of economy. This article searches whether foreign investment stock in a company＇s equity capital provides a stimulus for an industrial change at a micro level （five regions and 12 manufacturing sectors in accordance with statistical classification of economic activities NACE 2 Rev. （Nomenclature generale des Activities economiques dans les Communuates Europeennes） two-digit level） and whether this change contributes to the regional growth. Unbalanced regional growth as a result of reallocation of financial resources among sectors of economic activity and differences in distribution of economic success at a sectoral level provide a useful foundation for testing the impact of foreign direct investments （FDI） on changes in economic structure.

Analysis of SNPs in the Promoter Region of the Growth Hormone(GH) Gene in Mini-pigs

Single nucleotide polymorphisms(SNPs) of the growth hormone(GH) gene were investigated in six pig breeds,consisting of four mini-pig breeds(Wuzhishan,Bama,Xiang and Tibet pig),and two others(Dahlan and Landrace pig).Three pairs of primers for promoter regions of the GH gene were designed on the basis of the pig genomic sequence and SNPs were detected by the PCR-SSCP method.The results indicated three mutations in the 5’-flanking region.The analysis results showed that the frequencies of allele A and D in four mini-pig breeds were higher than that in other breeds at a locus within the 5’-flanking region(P【0.05).These results suggest that differences in body size may be associated with these SNPs of 5’-flanking region and amino acid mutation of the signal peptide of GH in these pig breeds.

Water Resource and Regional Economic Growth Study Based on Panel Data

Empirical analysis to the relationship between water resource scarcity degree and economic growth were done by building relationship model between water resource scarcity degree and regional economic growth with provincial panel data of 30 provinces during 2000-2009. The analysis results show that, in water resource scarcity regions, the shortage of water resource is the key factor of restricting economic development. In order to alleviate the shortage of water resource and meet the needs of economic development to water resource, it is necessary to speed up the establishment of water right trading market and finally achieve the goal of water-saving and regulation of water resource by economic leverage. The specific countermeasures include： first, comprehensively considering the endowment difference of water resource when carrying out industrial planning and layout; second, speeding up the establishment of water right trading market and revising water-saving incentive mechanism; third, increasing fiscal transfer payment ability to the provinces of outputting water resource; fourth, strengthening industrial guidance, making moderate industrial transfer and population movement; fifth, paying attention to science, technology and education investment, to improve utilization efficiency of water resource.

Turn regional divide into sustained growth potential—Taking advantage of regional gaps in fighting crisis and maintaining growth

Regional economic disparities are often regarded as signs of a country’s uneven or backward development.After analyzing China’s regional economic performances from 2003 to 2007,this paper concludes that the emergence of interior regions provides new momentum for China’s economic growth,and regional disparities can be taken as an important source in countering the current economic cycle and maintaining rapid growth.

A method for determining vegetation growth process using remote sensing data: A case study in the Three-River Headwaters Region, China

Accurate measurements of the associated vegetation phenological dynamics are crucial for understanding the relationship between climate change and terrestrial ecosystems. However, at present, most vegetation phenological calculations are based on a single algorithm or method. Because of the spatial, temporal, and ecological complexity of the vegetation growth processes, a single algorithm or method for monitoring all these processes has been indicated to be elusive. Therefore, in this study, from the perspective of plant growth characteristics, we established a method to remotely determine the start of the growth season(SOG) and the end of the growth season(EOG), in which the maximum relative change rate of the normalized difference vegetation index(NDVI) corresponds to the SOG, and the next minimum absolute change rate of the NDVI corresponds to the EOG. Taking the Three-River Headwaters Region in 2000–2013 as an example, we ascertained the spatiotemporal and vertical characteristics of its vegetation phenological changes. Then, in contrast to the actual air temperature data, observed data and other related studies, we found that the SOG and EOG calculated by the proposed method is closer to the time corresponding to the air temperature, and the trends of the SOG and EOG calculated by the proposed method are in good agreement with other relevant studies. Meantime, the error of the SOG between the calculated and observed in this study is smaller than that in other studies.

The Role of China's High-Tech Zones in Its Regional Economic Development

National high-tech industrial development zones represent a major strategy of the Chinese government in developing high-tech industries and spurring regional economic growth. The effect of this policy is yet to be proven. Based on the panel data of 283 Chinese cities between 1984 and 2012, this paper investigates the effect of high-tech zones on regional economic development. Empirical results suggest that first, national hightech zones have remarkably enhanced regional GDP and per capita GDP growth, and this conclusion still holds true after multiple rounds of robustness test; second, the economic effect of national high-tech zones is subject to diminishing marginal return and compared with higher-tier cities, lower-tier cities benefited more from the creation of national hightech zones. This paper concludes that national high-tech zones where special policies are experimented and offered not only drive economic development but, if properly distributed across regions, may help reduce regional economic disparities as well. The results of this study provide important implications for the future distribution of national high-tech zones and the creation of other relevant policies.

Seismicity acceleration model and its application to several earthquake regions in China

With the theory of subcritical crack growth, we can deduce the fundamental equation of regional seismicity acceleration model. Applying this model to intraplate earthquake regions, we select three earthquake subplates: North China Subplate, Chuan Dian Block and Xinjiang Subplate, and divide the three subplates into seven researched regions by the difference of seismicity and tectonic conditions. With the modified equation given by Sornette and Sammis (1995), we analysis the seismicity of each region. To those strong earthquakes already occurred in these region, the model can give close fitting of magnitude and occurrence time, and the result in this article indicates that the seismicity acceleration model can also be used for describing the seismicity of intraplate. In the article, we give the magnitude and occurrence time of possible strong earthquakes in Shanxi, Ordos, Bole Tuokexun, Ayinke Wuqia earthquake regions. In the same subplate or block, the earthquake periods for each earthquake region are similar in time interval. The constant α in model can be used to describe the intensity of regional seismicity, and for the Chinese Mainland, α is 0.4 generally. To the seismicity in Taiwan and other regions with complex tectonic conditions, the model does not fit well at present.

A STUDY ON ENVIRONMENTAL EVOLUTION OF BEIJING-TIANJIN-TANGSHAN REGION FROM JIN DYNASTY TO THE REPUBLIC OF CHINA (A.D. 1153-1949)

Studies of the law and characteristics of population and land-use development of the Bejing-Tianjin-Tangshen region from 1153-1949 indicated that the land development process in the region is closely related with population change of the corresponding period In Jin Dynasty, population increased rapidly, in Yuan and Ming dynasties, population increased with a sustainability while from Qing Dynasty to the founding of the Republic, population increased substatially.Wasteland reclamation and cereals cultivation by garrison and farmers appeared in Jin Dyasty and reached climax in Ming Dynasty. Correlation analysis of poulation increase and cultivated area showed that they follow a linear equation which means that population increase and cultivated area expansion were at a similar rate.

Directional region control of the thermal fractal diffusion of a space body

We present a directional region control （DRC） model of thermal diffusion fractal growth with active heat diffusion in three-dimensional space. This model can be applied to predict the space body heat fractal growth and study its directional region control. When the nonlinear interference term and the inner heat source term are generalized functions, the relationship between the particle aggregation probability and the interference terms can be obtained using the norm theory. We can then predict the aggregation form of particles in different regions. When the nonlinear interference terms in the model are expressed as a trigonometric function and its composite function, our simulations show that the DRC method of thermal fractal diffusion is effective and has reference value for the directional control of actual fractal growth systems.

Effects of kallikrein gene transfer on penumbral microvascular proliferation and on regional cerebral blood flow following cerebral ischemia/reperfusion injury

BACKGROUND： Recent findings have demonstrated that the kallikrein-kinin system （KKS） participates in the pathological process of cerebral ischemia/reperfusion injury. Kallikrein gene transfer exhibits neural protective effects following cerebral infarction. OBJECTIVE： To observe the effects of kallikrein gene transfer on vascular proliferation in the peripheral infarct focus and on regional cerebral blood flow （rCBF） following cerebral ischemia/reperfusion injury. DESIGN, TIME AND SETTING： The completely randomized, controlled experiment was performed at the Lin Baixin Laboratory Center, the Second Affiliated Hospital of Sun Yat-sun University between September 2007 and April 2008. MATERIALS： pUCI9-HTK plasmid was constructed and maintained in the Laboratory for Neurology, the Second Affiliated Hospital of Sun Yat-sen University, China. Mouse anti-human kallikrein 1 monoclonal antibody was purchased from R＆D Systems, USA. METHODS Ninety healthy, male, Sprague Dawley rats were used. Middle cerebral artery occlusion （MCAO） was established in all rats to induce cerebral ischemia/reperfusion injury. Following MCAO establishment, all rats were randomly divided into three groups （n = 30）： blank control, saline, and pAdCMV-HTK. The saline and pAdCMV-HTK groups were stereotactically micro-injected with 5μL of physiological saline or with pAdCMV-HTK [multiplicity of infection （MOI） = 20], respectively, into the ischemic penumbra. In the blank control group, only sham injection was performed. MAIN OUTCOME MEASURES： At 12, 24, and 72 hours after treatment, cerebral infarction volume was measured by 2, 3, 5-triphenyltetrazolium chloride （TTC） staining. Exogenous HTK expression, as well as regional vascular endothelial growth factor （VEGF） expression, was detected by immunohistochemistry. rCBF was examined by 14C-iodoantipyrine micro tracing. In addition, neurological severity score （NSS） was performed. Higher scores indicated more severe neurological deficits. RESULTS： NSS results demonstrated that compared with the saline and the blank control groups, the pAdCMV-HTK group exhibited lower NSSs 24 hours after pAdCMV-HTK injection （P 〈 0.05）. The NSSs were further decreased after 72 hours （P 〈 0.01）. Cerebral infarction volume at 24 hours, and in particular at 72 hours after treatment, was significantly reduced in the pAdCMV-HTK group compared with the blank control and saline groups （P 〈 0.05）. The rCBF in the area surrounding the infarction lesion was slightly decreased in all groups compared with the contralateral area. At 24 and 72 hours following treatment, the rCBF in the peripheral infarction lesion was significantly elevated in the pAdCMV-HTK group compared with the blank control and saline groups （P 〈 0.05）. Immunohistochemistry results revealed that VEGF-positive cells were primarily found in the cortex and in some white matter surrounding the cerebral infarction lesion. In addition, the expression of VEGF in the pAdCMV-HTK group was significantly higher compared with that in the blank control and saline groups at 12, 24, and 72 hours following treatment （P 〈 0.05）. CONCLUSION： Following cerebral ischemia/reperfusion, kallikrein gene transfer can promote vascular proliferation in the brain tissue surrounding the infarction lesion, improve rCBF, and reduce infarction volume, thereby exhibiting protective effects to attenuate neurological deficits.

高等教育规模、城镇化与区域经济增长机制研究——基于省级面板数据的证据

高等教育规模是经济持续增长的重要因素,城镇化是否在高等教育规模对区域经济增长的影响中发挥了重要中介效应,需要进一步研究。为此,可以基于2004一2020年国家统计局省级面板数据,分析高等教育规模与区域经济增长的关系,辨析城镇化在两者关系中的作用,进而探究高等教育规模、城镇化对区域经济增长的影响机理。研究结果表明:高等教育规模促进区域经济增长具有直接作用;城镇化对区域经济增长具有正向驱动作用;城镇化在高等教育规模促进区域经济增长过程中发挥了中介效应。这也证明了“高等教育规模一城镇化一区域经济增长”机制的存在。为有效利用该机制,建议适度扩大高等教育规模,加快培养高层次创新人才,因地制宜加快新型城镇化建设,推动城镇产业结构升级,建设现代化产业体系,促进区域经济快速健康发展。

非(001)晶面促进激光单晶熔凝过程中柱状晶外延生长

当激光熔池内的柱状枝晶沿着熔池边界外延生长时,其方向并不严格平行于温度梯度,而是选择与基体一致的择优方向生长,因此基体取向可以影响柱状晶的外延生长行为。在使用激光金属成型/沉积技术修复昂贵的单晶部件时,需要考虑这一特性。现有研究已经实现了(001)晶面上的柱状晶完全外延生长进而获得完整单晶。然而由于叶片形状复杂,实际修复过程中可能会遇到的不同取向表面。论文对(001)和非(001)取向表面修复过程中的杂晶形成能力进行了比较研究,通过数值计算获得了控制微观组织的局部凝固变量,并将杂晶晶粒的体积分数作为量化单晶完整性指数。结果表明,与(001)晶面相比,多数非(001)晶面可以促进柱状晶的外延生长,进而获得更好的单晶完整性,实验结果也验证了这一结论。分析显示不同枝晶生长区域的边界是杂晶形成敏感区,两种晶面的差异在于边界数目及其位置。研究结果可以优化修复和制造应用中的沉积方向和激光加工窗口提供指导。
