Abstract

Studying the process and characteristics of urban land change in different phases of urbanization and different economic development is much important for understanding urban land change and management at a macro level. Taking the example of Jiangsu Province, the present paper studied the correlation between urban land change process and socioeconomic development from 1981 to 2003 on the basis of statistical data. The results showed the following three aspects. First, urban land area has changed periodically and the research duration can be divided into two periods: from 1981 to 1994 and from 1995 to 2003. In each period, the changing trend is the same, i.e. slow at first and then quick. Studying from the comprehensive change status, the characteristic of fluctuant change is significant with three acute change pinnacles in 1988, 1991 and 2002 which were corresponded to turning point years of economic development phases of Jiangsu Province respectively. Second, the synchronization between urban land change and urbanization level change is not strict. With the evolution of urbanization phases, the change pace of urbanization level increased remarkably, but urban land change rate did not increase significantly accordingly. Third, the area of urban land has exponentially increased with the increase of per capita GDP. In different economic development levels classified by per capital GDP, land resource cost for economic development is different, respectively 29.01 hm2, 26.34 hm2, 26.22 hm2, and 11.14 hm2 for the increase of 100 million RMB GDP when the per capita GDP is under 1000, 1000–2000, 2000–5000 and over 5000 RMB.  相似文献

Abstract

Since the reform and opening up, China’s export trade has maintained a rapid growth; meanwhile, China’s energy consumption has been increasing sharply. “High export and high energy consumption” has become the feature of China’s trade and economic development. In this paper, based on the input–output analysis approach, the authors have conducted an empirical study on the export trade and energy consumption of 21 trade industrial sectors. The results show that, China is a big net exporter of embodied energy. Assuming that the export growth rate of embodied energy maintains to be about 23.6%, the average annual growth rate of the past 32 years, and based on the input–output data of 2005, by 2030 China’s net export of embodied energy would be over eight times more than the aggregate energy production, which is obviously infeasible. As a country of very low per capita energy, China must change its export pattern, encourage or restrain the export of different industrial sectors according to their energy consumption intensity, and promote structural change of energy– efficient exported products, so as to achieve the sustainable development. Accordingly, the authors put forward some suggestions.  相似文献

Abstract

Energy is now becoming the bottleneck of urban and regional development. The paper takes Shandong Province, one of the most energy consuming provinces in China, as an example, uses quantity methods such as SPSS (Stastics Package for Social Science) cluster sampling and regression analysis, and applies quantity analysis, to analyze the situation of energy issues in Shandong province. The conflicts between the quick industrialization and increasing extensive economic development, between urban population and energy consuming per head, between the infinite energy consuming desire and the low level of managing system, and between the unstable world energy supply and the limited energy storage in China are the main factors of energy crisis in Shandong, which not only results in energy shortage, but also becomes the barrier of economic and social development. In order to ensure sufficient energy supply for Shandong province in the 21st century, we should take countermeasures, such as changing the economic development model, pursuing a multiple and high quality energy strategy, improving the intensive urbanization strategy, and building a scientific energy system.  相似文献

ABSTRACT

Against the backdrop of a heavy carbon lock-in energy structure, China has made considerable progress in renewable energy (RE) development and become a world leader in this area within a decade. Although existing research suggests that rapid RE growth is mainly due to the convergence of economic growth, green industry competition, and energy security concerns under a unique state-led model, they oversimplify the difficulty inherent in RE policy shifting supported by formerly weak pro-RE actors in China’s historical trajectory of a low-carbon transition. By exploring the interaction between international and domestic actors by means of a socialization-based coalition-building framework, this paper aims at analyzing how the capacity building of the RE coalition gets enhanced via institutional anchoring and resource reallocation in the climate socialization process and how the strengthened RE coalition has spurred transformation in China’s RE policy and the challenges they are confronted with.  相似文献

This study analyzed the impact of urbanization and the level of economic development on CO2 emissions using the STIRPAT model and provincial panel data for China. This study classified the 29 provinces of China into three groups (eastern, central, and western regions) and examined regional differences in the environmental impacts of urbanization and economic development levels. The results demonstrated that there was an inverted U-shaped relationship between urbanization and CO2 emissions in the central and western regions of China. However, we did not confirm the environmental Kuznets curve relationship between urbanization and CO2 emissions in eastern China, where CO2 emissions increase monotonically with urbanization. This study showed that the impacts of urbanization differ considerably. There was a U-shaped relationship between economic growth and CO2 emissions. However, the point of inflexion was very low, which indicates that economic growth will promote CO2 emissions in China. The share of the industry output value had a marginal incremental effect on CO2 emissions. There was a decreasing effect of population scale on CO2 emissions. Energy efficiency is the main factor that restrains CO2 emissions, and the effect was higher in regions with low energy efficiency.  相似文献

ABSTRACT

This paper establishes a diagnostic model for assessing the rationality of size structure of urban agglomerations (UAs) in China. The model is designed to determine from a three-dimensional index including size distribution index (SDI), size compactness index (SCI), and size efficiency index (SEI). The spatio-temporal pattern of size structure involving the studied 19 UAs and its implications are explored. The results indicate that size structure of China’s UAs advanced from a low rationality development stage to a moderate rationality development stage in 1995–2015. Among them, the SDI and SEI were reasonably high, and the SCI was relatively low. Spatially, the high rationality UAs were distributed across eastern China, while the low rationality UAs were located in western China. UAs with positive size structure possessed typically a dual- or multicenter urban structure, while UAs with negative size structure usually presented as a single-center structure. The evolutionary trajectories of rationality of size structure of UAs can be summarized as four different stages. Our findings suggest that, in addition to consolidating the status of national-level UAs, the development of regional-level UAs should be promoted. Also, the fostering focus and direction should be oriented toward an UA with dual- or multicenter spatial structure.  相似文献

中国城市化水平省际差异的成因探析   总被引:16,自引:0,他引:16  
1990~2000年中国城市化水平的省际差异已从原来的北高南低态势转变为目前东高西低的格局。这是由各地区不同的自然环境背景、人口分布与增长、经济发展水平,以及国家区域发展政策等因素的综合影响而形成的。对中国各省区1990年和2000年城市化水平与自然、人口、经济发展、工业化水平等四类12个指标的因子分析表明,区域城市化水平不仅与工业化水平或经济发展水平呈正相关,与人口密度、农业经济呈负相关,而且受工业化水平或经济发展水平的影响更为强烈。并且,随着社会经济发展和工业化推进,工业化因子对城市化的拉动效应在减弱,而综合经济发展对城市化的拉动效应在显著增强。  相似文献

The South American country Brazil is one of the richest countries in terms of natural resources, representing 14 percent of the world’s total biocapacity. However, the biocapacity (biosphere’s ability to generate resources and sequester waste) per capita in Brazil has shown a massive decline over the last five decades, while economic growth and urbanization have rapidly increased for the same period. Brazil is one of the largest creditors of biocapacity to the world, and biocapacity loss in Brazil can lead to devastating environmental consequences. Therefore, this work empirically investigates the influence of urbanization, economic growth, and industrialization on biocapacity controlling human capital from 1961 to 2016 in Brazil. The Bayer and Hack cointegration test, the Autoregressive Distributed Lag (ARDL) technique, and Hacker and Hatemi-J (J Econ Stud 39:144–160, 2012) causality tests are employed. The findings unfolded a U-shaped relationship between economic growth and biocapacity, evidencing that economic growth reduces biocapacity, but after achieving a threshold level, it promotes biocapacity. Urbanization has a negative relationship with biocapacity per capita, indicating that urbanization is a significant driver of the biocapacity loss in Brazil. Further, urbanization and economic growth Granger cause biocapacity. Lastly, relevant policy implications are proposed to overcome the reduction in biocapacity.

On account of the background of China’s “new normal” characterized by slower economic growth, this paper analyses the low-carbon economy status quo in the Beijing–Tianjin–Hebei region and empirically investigates the relationship between carbon dioxide (CO2) emissions and its various factors for China’s Beijing–Tianjin–Hebei region using panel data econometric technique. We find evidence of existence of Environmental Kuznets Curve. Results also show that economic scale, industrial structure, and urbanization rate are crucial factors to promote CO2 emissions. However, technological progress, especially the domestic independent research and development, plays a key role in CO2 emissions abatement. Next, we further analyze the correlation between each subregion and various factors according to Grey Relation Analysis. Thereby, our findings provide important implications for policymakers in air pollution control and CO2 emissions reduction for this region.  相似文献

Abstract

Carbon emission is the current hot issue of global concern. How to assess various contributing factors for carbon emission is of great importance to find out the key factors and promote carbon emission reduction. In this paper, the author constructs an identical equation for carbon emission, based on the economic aggregate, the economic structure, the efficiency of energy utilization, the structure of energy consumption, and the coefficient of carbon emission; by applying to LMDI decomposition technology, the author analyzes the carbon emission of China from 1995 to 2007 at industrial level and regional level. The results show that the expansion of economic aggregate is the main reason for China’ s rapidly increasing carbon emission and the increase of energy utilization efficiency is the key factor that can hold back the increase of carbon emission. In addition, the change of industrial structure or regional structure and the change of traditional energy structure have limited influence on the carbon emission, and their potentials have not yet been exploited. At the end of this paper, the author proposes the efforts that China should make to reduce carbon emission.  相似文献

中国的生态足迹与绿色发展   总被引:1,自引:0,他引:1  
从2008年开始,世界自然基金会(WWF)与中国环境与发展国际合作委员会(国合会)联合,通过与国内外智库的合作引入"生态足迹"理念,从自然资源消耗与"生物承载力"之间关系的角度来研究中国经济发展所面临的资源环境问题。研究表明,2007年人类在消耗着1.5个地球。过去半个世纪以来,中国的生态足迹总量2007年已经是1961年的4倍,尽管中国的人均生态足迹水平仍然低于世界平均水平,但是已经突破了1个地球的均衡水平。与全球平均类似,中国生态足迹中最主要的组成部分是碳足迹,占54%。解决中国的生态足迹超支问题,关键是降低碳足迹。目前,中国的能源供给仍然高度依赖于化石能源,超过一半的能源供给来自于煤炭,中国和世界其它国家一样将面临化石能源枯竭问题。中国作为一个处于经济快速发展过程中的能耗大国,应及时调整产业结构和基础设施供给模式,在积极应对气候变化的同时提前应对自身可能面临的能源问题。中国所面临的现实决定了中国不能重复发达国家的高增长高资源消耗的老路,需要转变经济发展方式,发展绿色经济,为全球走向可持续发展道路提供探索的机会。  相似文献

ABSTRACT

Industrial agglomeration is an essential and effective way to integrate resources and elements. Its impact on the green innovation efficiency of the tourism industry is a process of continuous development and dynamic change. This paper, based on the provincial panel data from 2006 to 2015, uses super SBM model to measure the green innovation efficiency of China’s tourism industry. The threshold regression model is employed to conduct empirical tests of the nonlinear threshold effect of agglomeration on the green innovation efficiency of tourism industry. The inter-provincial differences of various threshold effects and their possible causes are analyzed. Results indicate that the green innovation efficiency of China’s tourism industry is generally growing, while regional disparity is significant with a gradient decrease along the eastern-central-western regions. There is an obvious positive nonlinear relationship between tourism agglomeration and green innovation efficiency. It is also found that with the increase of agglomeration, its influence is at a high level. As the level of agglomeration crosses the first threshold, its impact is at a low level, and when it crosses the second threshold, the impact of tourism agglomeration is at an intermediate level. Finally, this paper proposes the basic path and some policy recommendations to promote the green innovation efficiency of the tourism industry in China.  相似文献

China has experienced considerable urbanization in the past 60 years,especially since the implementation of the Economic Reform and Opening-up Policy in 1978.In 1949,there were only 132 cities with an urban population of 27.4 million,while in 2008 China had 652 cities with a total urban population of 606 million.Such urbanization is attributed to the boost in the number of cities and the urban population.Urban expansion enhanced geographic inequality between the three major regions in China.Compared with the eastern and central regions,western China only has 19%of the total cities and 18%of the urban population.The urbanization rate was 37.2%for the western region in 2008,while it reached 53.3%for the eastern regions and 45.3%for central China.Using a geographic information system(GIS)and statistical analyses,this study aims at explaining the structure and spatial development of urbanization,and highlighting the current issues of urban inequality in western China during the past two decades.The paper drew following conclusions:(1)Urbanization disparities between eastern and western China have become increasingly obvious,but seem to be evolving slowly since the establishment of the government’s Western Development Priority Policy in 2000.(2)Cities of various sizes were expanded in western China,and the main factors affecting the urbanization are population numbers and density,government investment and geographic conditions.(3)Current patterns of urbanization in the western region are distributed unevenly between provinces.  相似文献

随着近年来我国碳排放总量的增加,一些西方国家开始把碳减排责任的矛头指向中国。为了明确中国碳排放的国际地位,运用历史唯物主义观点,从经济发展阶段视角进行了国际比较研究。首先运用IEA2011年公布的碳排放数据分析了我国2009年面临的碳排放形势,继而研究了工业革命以来中国碳排放的总体贡献情况,最后从经济发展阶段视角进行了国际比较研究。认为:①尽管我国当前的碳排放总量巨大,但人均碳排放量低于世界前10名的主要碳排放国家,碳排放强度与世界主要碳排放国家相比还存在一定差距;②我国的历史累计碳排放贡献及人均碳排放均较低,发达国家和地区的累计碳排放量达到世界累计碳排放量的近3/4;③与发达国家相同经济发展阶段相比,我国的人均碳排放和碳排放强度远低于主要发达国家和地区;④世界主要发达国家和地区在快速推进工业化的经济发展阶段普遍伴随着高碳排放。鉴于此,我们认为应该辩证地看待中国的碳排放,一方面中国当前的确产生了较大的碳排放,另一方面中国的经济发展阶段决定了这种碳排放规模和水平。发达国家的经济发展轨迹和碳足迹也表明,在工业化快速推进的过程中,一定程度的高碳排放是世界经济发展的客观规律。  相似文献

Abstract

Suburbanization in large cities is an important phenomenon in the process of urbanization development in China in recent decades, which plays a very important role in promoting city development, whereas some side effects on the eco-environment appeared at the same time. This paper, taking Xi’an City in China as a case study site, analyzed the features of population suburbanization and industry suburbanization and pointed out the impacts of suburbanization on urban eco-environment. Based on the research, suggestions of countermeasures for urban planning and municipal management of Xi’an City in protecting urban eco-environment and conserving natural ecology were put forward in the end.  相似文献

Abstract

This paper gives a systematic view of the new trends of global carbon finance innovation under the challenge of global climate change and in the process of transition to achieve economic growth from “high carbon” to ‘low carbon”, covering the following aspects: the structure, status quo and developing trend of global carbon market. The paper discusses the innovation in financial organization and service systems and governments’ overall guidance and policy support, and draws the conclusion that the world is undergoing massive changes with governments actively responding to carbon finance to embrace the tremendous opportunities for clean energy and climate change in financial industry. To seize the opportunity, a complete and overall carbon finance system of China should be put in the top of the agenda. Given the current tasks of energy conservation and pollution reduction and the growing demand for capital input, China needs to construct an clear of policy guidance, a diversified financia service system, and a multi-approach carbon finance system to intensify and widen the participation of financial industry, to expand financing channels for sustainable economy and spread risks, and finally, work out an inexpensive solution to the realization of China’s low carbon target.  相似文献

Abstract

China is experiencing a process of rapid industrialization and urbanization at the cost of agricultural land and environment, particularly in the costal areas. This study takes Jinan as a case presenting a time-series analysis of urban land expansion from 313 to 2003. The results show that the urban expansion of Jinan city mainly took place in the last 100 years, especially after the economic reform in 1978. Social development and economic growth, urban population growth and migration policies were factors driving the urban land expansion. Urban sprawl resulted in a disappearance of wetlands and a great loss of agricultural land, and over-pumping of ground water that led to disappearance of the city's feature, namely “the city of springs”.  相似文献
