The orderly transfer of the manufacturing industry is a major action in China’s industrial restructuring.From the perspective of industrial transfer,we used the concentration ratio to depict the trend of the industrial transfer of energy-intensive manufacturing in the eastern,central,and western regions since the policy of large-scale development of western China was implemented.We measured the total factor productivity(TFP)of western China using the DEAMalmquist index method.We conducted a regression analysis to measure the effect of western China’s undertaking of the transfer of the energy-intensive manufacturing industry.The findings of this study show that during 2000–2019,eleven provinces(as well as autonomous regions and municipalities)in western China undertook the transfer of the energy-intensive manufacturing industry from the eastern and central regions to varying degrees,exhibiting significant phase features regarding the rate and scale of transfers.Further investigation also demonstrated that the transfer of energy-intensive manufacturing industries has a U-shaped enabling effect on TFP in western China with the scale effect greater than the technology effect.Therefore,it is necessary to transition from“extensive industrial transfer”at the cost of the labor force,land,and resources to“modern industrial transfer”featured by technology and efficiency improvements to contribute to industrial restructuring in western China effectively. 展开更多

In recent years,with high-speed development of economy and society,and fast propulsion of industrialization and urbanization process in the development zone,average annual land demand in the development zone also quickly enlarges,and the contradiction between high-speed growth of economy and shortage of land resources is apparent increasingly. Meanwhile,to guarantee crop safety and stick to 0. 12 billion hm2of farmland red line as a rigid constraint which could not be exceeded,the supply-demand contradiction of industrial land is more and more prominent. With industrial land scale continues to enlarge,land resources become more and more scarce,but there exists the phenomenon of low-efficiency land use and even idle. For land use characteristics of the development zone,taking Hefei City Economic and Technological Development Zone as an example,the countermeasures of perfecting industrial land transfer mechanism in the development zone are proposed. 展开更多

Theorists have discussed the Belt and Road Initiative relative to its political or policy implications, and world response to it has focused on analysis and commentary that assesses it geopolitically, with some even calling it a power play by China. Although the Belt and Road Initiative was proposed and has been promoted by China, it fundamentally is being developed within and adapted to laws of international industrial transfer and worldwide economic development trends, founding the initiative on universality and objectivity. The Belt and Road Initiative is an upgraded version or a new phase of the Go Out strategy adopted by the Chinese government to encourage Chinese enterprises to look abroad, which has been an important part of international industrial transfer. China is becoming a major output source in this new round of international industrial transfer, and the countries along the Belt and Road have become the major recipients. The new growth center of the global economy is likely to emerge along the Belt and Road, but the question of which countries in particular will take the lead in industrializing and accelerating economic growth through this industrial transfer will be decided in part through conditions such as development stage, technical maturity, cost level, and geographical location and in part through internal and external policy adjustment and choices made by the participating countries. 展开更多

In the last two decades, China has become one of the areas that have the greatest potential in industrial production, thus it has ranked second only to USA in the flow of international capital. By the end of 1998, the real value of FDI (Foreign Direct Investment) in China has utilized has added up to $268.1 billion. The big flow of FDI has not only promoted the development of social economy, but also worsened the existing regional difference by choosing spatial location. Under this circumstance, China’s economy faces new restrictions and opportunities while adjusting its regional structure and industrial structure. So it is more and more important for us how to seize the opportunity, to seek the regularity of FDI in choosing location from the aspect of space, to set up relevant strategy to direct FDI at inland regions (areas deficient of capital), and to make appropriate policies, esp. the industrial and regional policies so as for FDI to exert positive influence and avoid negative influence on China and its regional economy and society. Based on the latest domestic and overseas materials and data of the FDI in China, combining with the investigation of the enterprises, this paper has systematically revealed the progress of development of the FDI in China and the developing conditions of the main enterprises directly invested by foreign capital since the reform and opening-up in China. The characters of FDI such as spatial concentration, transference as time goes on, change of the technical content and up-gradation of industrial structure and their forming mechanism have been studied. Then the basic conclusions have been made as follows. Firstly, FDI has been highly concentrated in space. But as time goes by, it has been transferring from coastal regions to inland ones, from big cities to their surrounding districts, and the degree of concentration is decreasing. Secondly, the technical content of the invested projects has gradually increased and the up-gradation of the industrial structure is obvious. Thirdly, the regional choice of the FDI in China is mainly affected by labor and other productive factors. The relative change of the cost of productive factors in different regions since the reform and opening-up is one of the main factors that have caused the spatial transference of the FDI in China. Fourthly, as people’s income increases and the accumulation of the capacity of the technique and labor advances, FDI whose aim is to get more market has increased and tended to transfer from coastal regions to inland ones. Fifthly, the changes of the industrial structure of the main areas and countries who have directly invested in China and the changes of inter-regional industries and regional policies in China are also the important factors that affect the industries directly invested by foreign capital and their spatial transference. 展开更多

In order to study the current situation of land transfer in the process of agricultural industrialization in the Qinling-Daba Mountains(Shiyan),27 villages of 14 townships(towns) of six counties(cities) were visited and investigated through questionnaires,and the current situation and characteristics of land transfer among large professional households( large grain producers),family farms,agricultural enterprises and cooperatives in the process of agricultural industrialization were analyzed and summarized. The main issues affecting land transfer were summarized,such as big difference of inflow and outflow will,single way of land transfer,high cost of planting,weak agricultural infrastructure,a lack of production and operation technology,insufficient funds and short land transfer period,and imperfect social security system.Meanwhile,some countermeasures were proposed,such as improving land transfer system,precise subsidy policy and social security mechanism of Shiyan City,guiding long-term and normalized land transfer,strengthening training of professional skills and improving the quality of human resources,actively promoting the " three-township project",and attracting the investment in land transfer projects. 展开更多

On the strength of the status quo of Chinese land transfer,the changes of the county agricultural production factor market arising from land transfer from four aspects covering land market,agricultural capital market,agricultural labor market and agricultural science and technology.The impacts of land transfer on county agricultural industrialized development are analyzed:in the first place,the large amount of land required by the county agricultural scale production can be effectively supplied;in the second place,a large number of labors required by the county agricultural industrialized production can be effectively fulfilled;in the third place,the innovation of science and technology provides motivation for adjusting the county agricultural industrial structure.On the basis of that,the countermeasures on promoting the county economic development are put forward:firstly,the land transfer market should be standardized to ensure the sustainable and stable development of county agricultural industrialized development;secondly,the commercial value,variations and added value of the county agricultural products should be improved;thirdly,the input on the county agricultural capital should be ensured. 展开更多

In recent years, high-polluting industries have been gradually shifted from the eastern developed regions to the central and western underdeveloped regions in China. Certain environmental regulations have been in place accordingly in various regions, but the pollution in the central and western regions has risen sharply. Based on the data of interprovincial panel in China from 2006 to 2015, this paper calculates high-pollution industry dynamic agglomeration index, environmental pollution agglomeration index and relative environmental regulation intensity index, and uses Generalized Method of Moments to carry out the regression analyses of the whole samples,regional heterogeneity and temporal heterogeneity. The results show that there is an inverted Ushaped relationship between relative environmental regulation and environmental pollution concentration in China. The concentration degrees of industrial wastewater pollution and industrial waste gas pollution are deepened, which are mainly caused by the transfer of highly polluting industries. However, the concentration of industrial solid waste pollution caused by the transfer is not obvious. Furthermore, the deepening of industrialization intensifies the concentration of regional environmental pollution. Environmental Kuznets Curve does exist in China,but it is not significant. The increase of labor cost and quality will reduce the concentration of environmental pollution. 展开更多

Annular centrifugal extractors(ACEs) offer advantages including excellent hydraulic and mass-transfer performance, small hold-up volume, short residence time,and thus low solvent degradation, high nuclear criticality,easy start-up and shut-down, high compact structure.Therefore, ACEs have attracted increasing interest for future nuclear processing schemes, including the partitioning of high-level liquid waste(HLLW). Laboratoryscale and pilot-scale ACEs have been applied in demonstration tests of the trialkyl phosphine oxide(TRPO) process for HLLW partitioning. In this study, an industrialscale ACE(260 mm in rotor diameter) with magnetic coupling and a ‘‘hanging'' rotor structure was developed for the TRPO process. Moreover, a series of hydraulic and mass-transfer tests were carried out in the industrial-scale ACE. The maximum throughput can reach 10 m^3/h under suitable operation parameters when kerosene is used as the organic phase, and water is used as the aqueous phase. The influence of the total flowrate, the flow ratio(aqueous/organic, A/O), and the rotor speed on the liquid hold-up volume was determined. The extraction stage efficiency is higher than 98% under test parameters for extraction of Nd^(3+) and HNO_3, using 30% TRPO kerosene as theextractant from an HNO_3 solution containing Nd. All results show good performance of the industrial-scale ACE for the TRPO process. 展开更多

This paper studies the industrialization of China, a key problem of Chinese economic development with self-organization theory in system science. The dual economic structure of modern industry and traditional agriculture existing simultaneously is the typical economic structure for most developing countries. How can we break the dual economic structure? After China has carried out the peasant family output-related system of contracted responsibilities, the rural enterprises which develop swiftly and violently are setting up a bridge between traditional agriculture and modern industry. This paper models the triple economic structure formed by traditional agriculture, rural enterprises and modern industry. From the study of structure evolution, we obtain the important relationship between economic growth rate, the rate of technological progress, the growth rate of capital and the growth rate of population, deduce three critical points of population growth, and find out the conditions under which the national economic system forms a stable and orderly self-organized structure. On the basis of quantitative analysis, we propose an approach to the strategies of industrialization of China, especially to the problem of rural enterprise development and rural labor transfer, and give three conclusions and four developmental strategies about national economic system. 展开更多

Ever since the 1960s, especially 1980s, under the background of quickening pace of economic globalization and the regional division of labor around the world, the transfer of manufacturing industries among countries and areas gets great momentum and impetus. During 20-plus years in which China has adopted the policy of opening-up and reforming, our country has played an active role in taking part in the transfer of manufacturing industries. It advances the structural change of national manufacturing industries, accelerates national industrialism and promotes the comprehensive development of regional economics. In this paper, the author makes some initial study on the regularity of transfer of International manufacturing industries, discusses the profound impact of such shift on our national resources, environment, economics and society, and also proposes corresponding suggestions on how to implement the strategy of sustainable development in the process of the shift. 展开更多

Will developed countries turn China into a haven for "dirty" industries through international trade by specializing in producing and exporting "clean" products and importing pollution-intensive products from China? How does international trade affect Chinese industries' CO2 emissions? This paper presents an empirical test of these hypotheses using statistical techniques such as the environmental input-output model and net exports as a proportion of consumption(NETXC) based on the trade data of 20 industries in China,and G7 and OECD developed countries.In this study,we draw three conclusions:(1) The proportion of domestically produced CO2 emissions in CO2 emissions embodied in products exported from China has been declining;(2) Industries migrated or displaced from developed countries into China include both "dirty" and "clean" industries;(3) International trade can help industries reduce CO2 emissions in aggregate and per unit of output.China has not become a haven for developed countries' "dirty" industries as a result of international trade. 展开更多
