Spatiotemporal pattern of climate change in the China-Myanmar Economic Corridor from 1901 to 2018

The China-Myanmar Economic Corridor(CMEC) is an important part of China's Belt and Road Initiative and an important area for global ecology and biodiversity. In this study, the annual and seasonal spatiotemporal patterns of temperature and precipitation in the CMEC over the past century were investigated using linear tendency estimation, the Mann-Kendall mutation test, the T-test, and wavelet analysis based on the monthly mean climatic data from 1901 to 2018 released by the Climatic Research Unit(CRU) of the University of East Anglia, UK. The results show that the CMEC demonstrated a trend of warming and drying over the past 100 years, and the rate of change in Myanmar was stronger than that in Yunnan Province of China. The warming rate was 0.039 ℃/10a. Precipitation decreased at a rate of -6.1 mm/10a. From the perspective of spatial distribution, temperature was high in the central and southern, low in the north of the CMEC, and the high-temperature centers were mainly distributed in the southern plain and river valley. Precipitation decreased from west to east and from south to north of the CMEC. From the perspective of the rate of change, warming was stronger in central and northern CMEC than in southern and northeastern CMEC. The rate of precipitation decline was stronger in the central and western regions than in the eastern region. This study provides a scientific reference for the CMEC to address climate change and ensure sustainable social and economic development and ecological security.

Exploring the impact of economic growth and energy consumption on SO_(2) emissions in China based on the Environmental Kuznets Curve hypothesis

This study aims to analysis the influence of economic growth(EG)and energy consumption(EC)on sulfur dioxide emissions(SE)in China.Accordingly,this study explores the link between EG,EC,and SE for 30 provinces in China over the span of 2000-2019.This study also analyzes cross-sectional dependence tests,panel unit root tests,Westerlund panel cointegration tests,Dumitrescu-Hurlin(D-H)causality tests.According to the test results,there is an inverted U-shaped association between EG and SE,and the assumption of the Environmental Kuznets Curve(EKC)is verified.The signs of EG and EC in the fixed effect(FE)and random effect(RE)methods are in line with those in the dynamic ordinary least squares(DOLS),fully modified ordinary least squares(FMOLS)and autoregressive distributed lag(ARDL)estimators.Moreover,the results verified that EC can obviously positive impact the SE.To reduce SE in China,government and policymakers can improve air quality by developing cleaner energy sources and improving energy efficiency.This requires the comprehensive use of policies,regulations,economic incentives,and public participation to promote sustainable development.

Transformation power or development pressure:economic growth targets and urban carbon productivity

Maintaining moderate economic growth targets(EGTs)is the key for local governments to effectively implement the“carbon peak and carbon neutrality”goals under the refreshed development pattern.Utilizing panel data of 276 prefecture-level cities in China's Mainland from 2010 to 2020,and employing methods such as intermediary and threshold models,this study empirically analyzes the internal mechanism of EGT’s impact on urban carbon productivity(UCP).Our findings demonstrate that:①The overall EGT during the analyzed period is not conducive to improving UCP.This conclusion remains valid after a series of robustness tests.This effect is more pronounced in the central region and resource-based cities than in the east-west region and non resource-based cities.②EGT not only directly suppresses UCP but also exerts indirect negative impacts on UCP from three aspects:delaying the digital economy(DE),constraining financial expansion(FE),and hindering green technology innovation(GTI).This negative indirect effect is similar to or even surpasses the direct effect,suggesting that the internal relationship between EGT and“dual-carbon”goals should be re-evaluated from a new compound perspective.③EGT not only has a simple linear impact on UCP but also significantly exhibits a dynamic evolution pattern in inverted“U”shape.That is,as EGT continuously upgrades,a nonlinear impact on UCP emerges in the form of“promoting first,suppressing later”.This indicates that surpassing the“degree”limit for EGT will be detrimental to the improvement of UCP.This study broadens the scope of carbon productivity analysis by introducing a new perspective centered on EGT.The insights gleaned from this research offer valuable guidance for local governments to effectively manage economic growth expectations and promote the synchronized achievement of dual-carbon objectives.

Research on the Digital Economy's Impact on China's Economic Growth:Based on the Variations in Urbanization Levels Across China's Eastern,Central,and Western Regions and Sectoral Heterogeneity

This paper uses inter-provincial panel data from 2011 to 2017,a linear regression model,and a threshold model to conduct empirical analyses of the impact of the digital economy on China's overall economic growth and the three main sectors of industry.The paper then investigates the impact and effects the digital economy has had on the economic growth of the three main sectors of industry in China's eastern,central,and western regions.Finally,the paper investigates the most significant differences among the various regions and the threshold effects of urbanization levels on the relationship between the digital economy and economic growth.The findings indicate a significantly positive correlation between the digital economy and regional economic growth.Moreover,geographical factors notably influence this correlation.The digital economy exerts a positive effect on all sectors of industry.It may not substantially impact industrial development in regions with highly developed infrastructure.Regarding the other regions,the digital economy exhibits varying degrees of impact due to the differences in the specific indicators.The conclusion drawn by the threshold model is that the magnitude of the threshold effect correlates with geographic factors.No threshold effect was observed in the eastern region,while the threshold effect occurred in the central region when the urbanization levels for the provinces were below 0.6645.Similarly,the threshold effect was noted in the western region when the urbanization level was below 0.3931.Considering all of this,the study also offers policy recommendations that will help balance the regional development of digital economies,accelerate the digital transformation of traditional industries,enhance digital infrastructure construction,refine the formulation and implementation of data policy,and establish relevant incentive mechanisms.

Overcoming the contradiction between promoting economic growth and transforming the economic growth pattern

Promoting economic growth has become the first and foremost objective of macro-control since China experienced a drastic economic downturn in the fourth quarter of 2008. Now China is at a special stage of transition characterized by the transformation of the economic growth mode. While promoting economic growth, the government must effectively coordinate the relationship between economic growth and the transformation of growth mode. This is not a task that can be done easily. To promote economic growth, the central government has selected a number of industries and formulated an industrial revitalization plan for each of these them. Revitalizing these industries helps promote economic growth at the present stage but propelling these industries alone still cannot fully meet the requirements for transforming the economic growth pattern. To coordinate the relationship between promoting economic growth and transforming the economic growth pattern, it is currently imperative to adjust China’s industrial upgrading strategy and to pay attention to intra-industrial upgrading, particularly process upgrading.

Can Emerging Economies Catch-up Sustainably？-An Analysis of BRICS＇ Economic Growth Pattern

The BRICS （Brazil, Russia, India, China and South Africa） and other emerging economies have become a driving global force for the past twenty years. However, their growth patterns are obsolete, impeding the quality and competitiveness of their economic growth, while simultaneously threatening the sustainability of their economic convergence with developed nations. Transforming the domestic growth pattern-the solution to the middle-income trap-has therefore become a key priority for each of these economies. This paper presents a comparative analysis of how to transform the pattern of economic growth in BRICS and achieve sustainable economic convergence with a comparative analysis of the pattern of economic growth and problems among BRICS countries.

Economic Growth:The Fundamental Path to the Realization of Social Security Rights for Migrant Workers

The International Labour Organization seems to only see the aspect of social security promoting economic growth,while neglecting the aspect of economic growth supporting social security.From the standpoint of materialism and the practice of social security,the realization of social security rights for migrant workers fundamentally depends on economic growth.The Belt and Road Initiative has provided a Chinese solution for creating a strong material and technological foundation to meet the social security needs of all people,including migrant workers.

Resource constraint,sustainable economic growth pattern and transformation of economic system in China

Over the past 20 years, China has made spectacular achievements in economic growth as well as in thetransformation of economic growth pattern. Industrial structure is being updated, and technology is playing a more andmore important role in economic development. The energy and resource consumption in many industries and enterprisesare reducing. However, we should realize that there are still many problems in changing the economic growth pattern,such as high input, high consumption, high discharge, inharmony, recycling difficulty, and low efficiency, which havegreatly impaired and restrict Chinese economic development. Therefore, the fundamental change of the economic growthpattern is inevitable. Based on the analysis on the status quo and the exploit of resources, this paper suggests that thetransformation from unsustainable to sustainable growth is the only choice in changing the economic growth pattern. Inaddition, the transformation should not completely rely on the fundamental effects of market mechanism. We should makefull use of the power of governments to speed up the transformation of economic system.

Patterns of Correlation between Aviation,Education,and Economic Growth in Developing Economies

Statistically significant is the fact that aviation has a positive correlation with the economic growth of nations.Developing countries in particular,and most economies of the world,in general,have widely observed that aviation is not only a catalyst for economic growth,it is also a business enabler and a global market share enhancer for many businesses across the globe.Notwithstanding this logically understandable and intuitive statement,it is interesting to note that the relationship and dependencies of education,culture,economy,and aviation policy of developing countries to capitalize this potent element for politico-socio-economic growth of nations is more often than not,ignored or underestimated.This paper studies and attempts to identify patterns in the correlation of factors related to Human Resource Development that boosts the growth of the aviation industry;specifically analyzing and comparing countries like Singapore,UAE,Qatar,Turkey and few others with lesser-developed,but growing economies like Pakistan.Derived from analytical study and inferences,the paper suggests and recommends a proven track for growth,prosperity,and socio-economic stability.The focus of the study is on the effect of education,training,and grooming of Human Resource specifically engaged in the fast-growing global aviation industry.

Assessment of China's Qualitative Demographic Dividend for Economic Growth during 2016-2020

Given the great strides that China＇s education sector has made in recent decades, it can be expected that the overall workforce quality of exiting China＇s labor market in coming one or two decades will be relatively low, while the overall quality of workforce newly entering into China＇s labor market will be high. As the new, bettereducated generation takes over, China＇s workforce quality will be vastly improved. This in turn will promote economic growth. We refer to economic growth arising from improved workforce quality as qualitative demographic dividend. Using the computable general equilibrium （CGE） model, this paper investigates the relationship between workforce quality improvements and economic growth. According to the model＇s results, an improvement in workforce quality will raise the economic growth rate by about two percentage points per annum between 2016 and 2020 and by 10 percentage points cumulatively by 2020. In other words, GDP will be 1.1 times the level of baseline GDP by 2020 due to the improved education levels. Given different production functions across sectors, the improvement of workforce quality will affect different sectors in different ways. On the whole, the improvement of workforce quality is more favorable to the development of capital-intensive sectors and sectors with rapid technology progress. According to this paper, considering the improvement of workforce quality, we cannot conclude that China＇s potential economic growth rate has already begun to decline. Despite diminishing conventional quantitative demographic dividends, China ＂s qualitative demographic dividends will keep rising. Qualitative demographic dividends will further push forward China＇s industrial restructuring and the strategic transition of industrial competitiveness from quantitative to qualitative and from an extensive to an intensive pattern of development.

Cointegration analysis with structural changes between consumption and economic growth in China

In order to investigate the existence of a stable long-run equilibrium relationship between economic growth and consumption in China, the relationship between the gross domestic product （GDP） and consumption in China was investigated by the cointegration analysis method. Using the Engle-Granger （EG） test and considering the possibility of structural changes, the impact of external economic shocks on the long-run equilibrium relationship between economic growth and consumption in China was analyzed. Analysis results show that without considering structural changes, the EG test cannot detect cointegration in the series subjected to structural changes; in considering structural changes, cointegration is successfully detected by specifying the dummy variable. In addition, the error correction models were constructed in different periods. This study verifies the existence of a long-run equilibrium relationship between economic growth and consumption in China, and this relationship has significantly changed in 1989 and 1997, respectively.

Supply-Side Structural Reforms and China's Potential Economic Growth Rate

This paper examines the effect of supply-side structural reforms on China＇s potential economic growth rate in the coming decade according to the data the authors have gathered. Under the rapid growth scenario with the implementation of supply-side structural reforms, China＇s potential economic growth rate will reach an average of 6.5% and 5.8% respectively in the 13th Five-year Plan （2016-2020） and 14th Five-year Plan （2021-2025） periods. These rates are 0.2 and 0.3 percentage points higher, respectively, than that under the baseline scenario with the inertia of historic trends. In implementing supply-side structural reforms, China must transform governmental functions, break monopolies, create a comprehensive competitive market environment, foster the creation of pro-innovation mechanisms, refocus on quality and efficiency, and raise capital utilization and labor productivity.

Effects of Different Planting Patterns on Rice Yield and Economic Benefit

[Objective] This study aimed to investigate the effects of cultivation methods on rice yield and economic benefits in the Dongting Lake area. [Method] A field plot experiment was conducted by adopting three different planting patterns of artificial sowing, artificial throwing and mechanical transplanting. [Result] Rice yield of mechanical transplanting was 7.84% and 24.19% higher respectively than that of artificial sowing and artificial throwing. The effective panicles per unit area of mechanical transplanting and artificial throwing were less than that of artificial sowing. On the contrary, grains per spike, 1 000-grain weight and seed setting rate of mechanical transplanting and artificial throwing were less than those of artificial sowing. Mechanical transplanting of rice brought the highest net income 11 779.16 yuan/hm2, which was 1 697.72 and 3 631.84 yuan/hm2 higher than that of artificial throwing and artificial sowing. [Conclusion] Mechanical transplanting could promote rice productivity in Dongting Lake area, and could increase rice yields and economic returns.

Chinese and US S&T Innovation Policies and Their Effects on Economic Growth Potentials

Since the eruption of the recent global financial crisis, major countries have been pushing forward structural reforms with science and technology （S＆T） innovation at the heart. Since taking office, US President Donald Trump has adopted an ＂America First＂ strategy but has yet to specify a clear S＆T innovation policy. However, Trump＇s current policies have already affected S＆T innovation and his planned budget cuts will impact US growth potentials. Compared with the US, China is steadily implementing its innovation-driven development strategy with significant improvement in S＆ T innovation that increasingly supports economic growth. To spur future economic growth, China should steadfastly follow its S＆T innovation strategy, promote the utilization of S＆T innovation results, boost its economic growth potentials and make the most of global innovation resources.

China’s Potential Economic Growths during 2015-2025 under Different Scenarios~

China has entered a crucial period of further growth and restructuring that will last until 2025. Based on a review of the major factors affecting China＇s potential economic growth, this paper has created an integrated economic system model consisting of system dynamics, econometrics, and input-output for the forecast of China＇s economic size and structure by 2025. Analysis shows that prior to 2025, China will be able to maintain a potential annual economic growth rate of 5.7%-7.2%. Faced with an international environment of a possible slowdown of advanced economies and diminishing demographic dividends, China needs to further expedite its urbanization process, enhance R＆D and education spending, increase total factor productivity （TFP）, vigorously develop the tertiary sector, and expand consumption in order to achieve the optimistically estimated growth of 6.6%-7.4% during the period of 2015-2025. Economic growth should be accompanied by the upgrade of industry structure and improvement of investment and consumption structures.

Transportation Infrastructure Quality Effect on Economic Growth： Evidence from the China Railway Speed-Up Campaigns

Beginning in 1997, China implemented a six-round campaign to accelerate train service, known as the ＂ China Railway Speed-Up Campaign＇＂ which greatly increased railway capacity and improved the quality of rail facilities. This can be seen as a natural experiment of the effects of improving the quality of transportation infrastructure. Using the Beijing- Guangzhou Line and the Beijing-Shanghai Line as examples, this paper creates city-level panel data for stations along accelerated lines and traditional stations for the years between 1994 and 2006 and systematically examines the campaign＇s effect on economic growth using difference-in-difference （DID） methodology. Our research concludes that railway acceleration has promoted economic growth in cities with stations on upgraded rail lines. Over the entire period of the speed-up campaign, the per capita GDP growth rate has risen by 3.7percentage points in cities with upgraded stations versus cities with traditional stations. Moreover, positive effects on economic growth have been found to increase in later stages of railway upgrades.

Spatial spillover effects of transport infrastructure on regional economic growth

Spatial spillover effects,either positive or negative,of transport infrastructure,highways/expressways,etc.,on regional economic growth are proposed.Using the panel data for 11 cities of Zhejiang province from 1994 to 2003,a spatial production function is applied to examine the spatial spillovers which can be generated as a positive output spillover from the transport infrastructure between neighboring cities.Some spatial weighted matrices are adopted to define different neighboring cities to measure how easily factors or economic activities can migrate between regions.The estimation results show that the output elasticity of the highway infrastructure in 11 cities are all insignificant at a 5% significance level;hence,highway infrastructure in a region cannot explain the same region's economic growth.On the other hand,the highway infrastructure of other contiguous regions has positive spillover effects on a same region's economic growth.

Ecological Problems and Countermeasures from the Perspective of Economic Growth——a Case Study of Jiangxi Province

Environmental pollution is deteriorating upon economy growth and will re- strain economy in turn. The research took Jiangxi Province as an example to seek existing problems on eco-environment, analyze causes and propose countermeasure in order to iay foundation for local economy development.

Spatial patterns of urban land use growth in Beijing

By using digitized land use maps of Beijing in 1982, 1992 and 1997 and employing GIS spatial analysis techniques, this paper conducts an empirical study on the spatial differentiation and spatial patterns of urban land use growth in Beijing in the period of 1982–1997. It is observed that urban land use growth in Beijing went beyond the control of urban planning, in terms of the extraordinary high growth rate and undesired spatial pattern. The rate of urban expansion after 1982, which was predominated by growth of industrial land, was extraordinary high compared to its historical period. While its growth centers have been actively shifting toward the northern part, rather than toward the southern and eastern parts as designated by the latest General Plan (1991–2010) of Beijing, its spatial pattern of urban land use growth in general was in distinct concentric sprawl, which seriously violated the General Plan of Beijing.
