The relationship between China’s urbanization and economic development(RCUED) is an important concern nationwide. As important actors in regional strategy and policy, county-level regions have played an increasingly significant role in the development of China’s social economy. However, the existing research on the RCUED lacks the fine depiction of the county-level administrative units.Using 2000 and 2010 census data and the statistical analysis method, we uncovered the evolution characteristics of China’s urbanization and economic development and conducted a quantitative identification for the RCUED with improved methods using the quadrant map approach. In addition, we investigated the spatial correlation effect of the RCUED using the spatial autocorrelation analysis method. The results were as follows: 1) In general, a high degree of matching exists between China’s urbanization and economic development at the county level at the significance level of 0.01. The correlation coefficients between China’s urbanization and economic development in2000 and 2010 were 0.608 and 0.603, respectively. 2) A significant regional difference exists in the RCUED at the county level. Based on a comparative analysis of 2276 county units in China in the two years, we found that county units can be categorized as under-urbanized, basic coordination and over-urbanized in various areas. No situation was observed where urbanization seriously lagged behind the economic development level, so the levels of urbanization and economic development appear to be basically coordinated,and the coordination state may be gradually optimized over time. 3) Over time, the spatial dependency of the RCUED has weakened and the spatial heterogeneity has increased. Northeast China has always been an area characterized by over-urbanization. The number of county units classified as under-urbanized has begun to decline in eastern coastal urban agglomeration areas, while counties rich in resources have transformed from having point-shaped over-urbanization to plane-shaped under-urbanization along the northern border,and the number of over-urbanized county units has increased in the middle reaches of the Yangtze River. 4)’Lag-lag’ type and ’advance-advance’ type accounted for 68% of all counties in China, and these counties were shown to have obvious spatial differentiation characteristics. 展开更多

The relationship between energy consumption and economic growth is becoming increasingly close. However, energy consumption is the major source of greenhouse gases, which can significantly affect the balance of the global ecosystem. It has become the common goal of countries worldwide to address climate change, reduce carbon dioxide emissions, and implement sustainable development strategies. In this study, we applied an approximate relationship analysis, a decoupling relationship analysis, and a trend analysis to explore the relationship between energy consumption and economic growth using data from Kazakhstan for the period of 1993-2010. The results demonstrated: (1) the total energy consumption and GDP in Kazakhstan showed a "U"-type curve from 1993 to 2010. This curve was observed because 1993-1999 was a period during which Kazakhstan transitioned from a republic to an independent country and experienced a difficult transition from a planned to a market economy. Then, the economic system became more stable and the industrial production increased rapidly because of the effective financial, monetary and industrial policy support from 2000 to 2010. (2) The relationships between energy con- sumption and carbon emissions, economic growth and energy exports were linked; the carbon emissions were mainly derived from energy consumption, and the dependence of economic growth on energy exports gradually increased from 1993 to 2010. Before 2000, the relationship between energy consumption and economic growth was in a recessional decoupling state because of the economic recession. After 2000, this relationship was in strong and weak decoupling states because the international crude oil prices rose and energy exports increased greatly year by year. (3) It is forecasted that Kazakhstan cannot achieve its goal of energy consumption by 2020. Therefore, a low-carbon economy is the best strategic choice to address climate change from a global perspective in Kazakhstan. Thus, we proposed strategies including the improvement of the energy consumption structure, the development of new energy and renewable energy, the use of cleaner production technologies, the adjustment and optimization of the industrial structure, and the expansion of forest areas. 展开更多

The relationship between urbanization and economic development has become a hot topic in the scientific community due to its great practical significance,and economic and social value.However,this relationship continues to change dynamically.In the new stage of urbanization,it is urgent to reveal the causal relationship quantitatively and diagnose the future direction systematically.Based on this,this paper calculates the contribution rate of China’s urbanization to economic development from 1978 to 2019 and uses the panel data cointegration test method to explore the causal relationship between urbanization and economic development in China.The study has three principal results.First,the contribution rate of urbanization to economic growth has maintained the overall growth trend from1978 to 2019,but the growth rate of urbanization’s contribution to economic growth has been relatively low since 2012.It is an important reason that the real estate sector has moved into a new stage of transformation.Second,the cointegration test shows that economic development is a significant factor in advancing urbanization and the urbanization is the product of economic development.Urbanization has a positive feedback effect on economic development,but this effect does not pass the 5%significance level test.The impulse response function shows that the impact of urbanization on economic development is relatively small and stable,indicating that it is limited that the boost of economic development by land-centered urbanization.Third,China’s urbanization and economic development have both shown rapid growth for some time,but their relationship is still the low level of coordination,which has also led to a downward trend in the contribution of new-type,people-oriented urbanization to economic growth in recent years.In the future,China’s urbanization and economy need to maintain relatively medium-low speed growth in the medium-long term,and we should boost the coordinated development of urbanization and economy from low level to high level. 展开更多

Eco-industry, circular economy, cleaner production, industrial ecology or industrial ecosystem and other subjects are all categories related to sustainable developinent. This paper studies the relations and differences between the four categories and sustainable development as well as ecological economics. Circular economy, eco-industry, industrial ecosystem and cleaner production were put forward during the revolution in “end treatment pattern” of traditional industrial society. Industrial ecology, eco-industry and circular economy theory are three content expansions of cleaner production. Ecological economics is of instructive function theoretically and methodologically for circular economy, eco-industrial, cleaner production and industrial ecology. Circular economy theory is easier to be accepted, compared with ecological economics theory. And circular economy in nature is the complete application of ecological economics theory. 展开更多

Decentralization is a global phenomenon,but growth is not.The economic relationship between central and local governments is an important yet unresolved question in China’s economic development.As a large country with unbalanced political and economic development,China is faced with unbalanced and inadequate development as the primary constraint to meeting people’s ever-growing needs for a better life.The Communist Party of China(CPC)has been exploring to mobilize the initiatives of both central and local governments.During the planned economy era,China experienced a few rounds of centralization of economic powers but failed to strike a balance in maximizing the initiatives of both central and local governments.After the reform and opening up policy enacted in 1978,China’s central and local governments have succeeded in combining economic decentralization with administrative decentralization.China’s central government,local governments and enterprises have become resource allocation entities.China’s economic growth miracle has been driven by promoting the initiatives of central and local governments.Entering the new era,the central-local economic relationship represents an institutional strength of concentrating resources to accomplish great undertakings and leveraging the initiatives of both central and local governments.With the principal contradiction facing China’s development shifted into one between people’s growing needs for a better life and unbalanced and inadequate development,the management of central and local government relationship has taken on greater theoretical significance and salient implications in the new era. 展开更多

British Economist Angus Maddison said that eco nomic development is a recent phenomenon inhuman history. Although human species have lived on the planet at least 2.5 million years, economic development only appeared around the 1850s. In pursuit of economic development, not all nationalities have been equally lucky. Among more than 200 countries in the world, only dozens of countries are devel oped. Onethird of the world's total population of 6.5 billion are living in poverty. In both developing and developed countries, the wealth gap is often obvious. Therefore, eco nomic development is the goal of each country, the aim of each politi cal party, and the wish of all people. However, economic development usually baffles people. As a result, understanding the relationship be tween economic development and human rights protection is a matter of urgency. 展开更多

Meanwhile they consume much of the global coal to fuel their economic development. With coal burning as a major factor contributing to global greenhouse gas emissions, China and India are confronted with a dilemma of economic growth and environment protection. Will coal consumption reduction cause economic shocks? Is there a causal relationship between coal consumption and economic growth in China and India? In this paper Granger causality tests were used to examine the relationship between coal consumption and GDP in China and India, using data for the period from 1965 to 2006. It was found that a unidirectional causality from GDP to coal consumption existed in China while a unidirectional causality from coal consumption to GDP did in India. Therefore, developing cleaner and more efficient technologies is essential to reduce their CO2 emissions to reach sustainable development. 展开更多

This paper establishes the evaluation index system of ecological environment and economic development in resource exhausted cities, and calculates the level of economic development and ecological environment during the year 2005-2012 by using the entropy method. Furthermore, this study analyzes the coordination degree and coordinated development degree by using the coordination model. The results show that the coordination relationship of economic development and ecological environment continues to improve from 2005 to 2012 in most of these resource exhausted cities. By 2012, other resource depletion cities are in all kinds of hierarchical coordination except Yichun and Hegang. From the standpoint of coordination development degree, although most of these resource exhausted cities have been increased continuously but the level is also lower except in Tongling and Xinyu. Finally, this paper puts forward the corresponding countermeasures and suggestions according to the results of the analysis. 展开更多
