This article utilizes three data envelopment analysis-based models: a no environmental regulation model, a weak environmental regulation model and a strong environmental regulation model to reveal the impact of environmental regulation on China’s regional total-factor energy efficiency (TFEE) during the period of 2003–2010. To take a further step, these three models are adjusted for calculating the correspondingly macro-economic cost of environmental regulation. The estimation results show that at present, the level of China’s environmental regulation is relatively low, and an enhancing of environmental regulation would lead to a sufficient increase of China’s regional TFEE with an enormous economic cost as its price. That means in China, the nationwide environmental stress is high, and the regulation cost is very huge. Strengthening environmental regulation would inevitably have some negative influences on China’s economy in the short run. Based on our findings, some corresponding policies are also proposed in this article.  相似文献

This paper examines the sources of labour productivity in the Italian regions during the period 1980–2004. Five economic sectors are investigated using data envelopment analysis (DEA) and taking into account productive specialisation and sector inefficiencies. Labour productivity change is decomposed into five components by means of Malmquist productivity indices: intra-sector efficiency change, composition efficiency change, input-biased technical change, magnitude component technical change and capital accumulation. Using bootstrap procedure, the components of labour productivity changes are statistically tested. Efficiency analysis shows that productive specialisation is not a source of inefficiency and efficiency gains can be obtained by sector-specific policies. Thus, it is possible to obtain improvements in efficiency in each sector of activity rather than reallocating resources among sectors. The results of the decomposition by sectors reveal heterogeneous sources of growth. The total economy has shown evidence of non-neutral technical change and, it has been found that agriculture, industry and construction experienced capital using technical change. The analysis of the decomposition of the labour productivity growth is complemented by an analysis of β-convergence.  相似文献

In a recent article using citation analysis Hoepner et al. (2012) make strong claims to have identified the most influential works, authors, journals and institutions in a hypothetical field they call environmental and ecological economics. This paper shows that their work is biased by its framing, far from the non-subjective approach they claim and highly sensitive to minor data errors. More than this the exercise can be seen as another example of how ecological economics is susceptible to suppression by a dominant mainstream economic perspective which attempts to override, belittle and dismiss a whole range of alternative thought, including that which is heterodox, interdisciplinary, from the natural sciences and based in the non-economic social sciences. Ecological economics is not the same as agricultural, resource or environmental economics, and if it were it would be pointless. Neither can it be understood or treated as a subfield of resource and environmental economics, as done by Hoepner et al. (2012). I argue that the study promotes a limited perspective on social, environmental and economic problems that includes an implicit political and ideological framing. What is most influential, important or high quality in ecological economics is certainly not defined by such work.  相似文献

EKC假说是指在经济发展早期环境质量逐渐恶化,经济发展到一定水平后,环境质量会逐渐改善,即环境压力和经济增长之间呈倒U形关系。文章以苏南地区1986—2004年经济发展和环境面板数据为基础,建立了苏南地区经济发展和工业污染排放的计量模型,以此来分析苏南地区经济增长与环境污染的演替轨迹。结果表明苏南地区环境污染与经济增长之间呈现N型波动EKC特征,工业污染排放量随着人均GDP的快速提高而波浪式地不断恶化,而不同于以往的经典理论中倒U型的形状。苏南地区依然处于污染排放量的增长期,如何抓住机遇,调整产业结构,加大环保投入,转变经济增长方式,平稳地实现转折,实现环境和经济的双赢是苏南地区可持续发展和率先实现全面小康的首要问题。  相似文献

This article investigates the dynamic relationship between economic progress and environmental quality at a regional level. An important economic intuition in this context is that environmental degradation will be limited by human behaviour if costs and benefits of such degradation are local since economic agents will then be incentivized to choose appropriate corrective action. Therefore, we note the likelihood that regional economic development can help regions ‘grow out of’ environmental problems. Using a new data set from Yangtze River Delta of China, we find a strong confirmation of the intuition that human can and will resolve the environmental problem by altering the damaging behaviour of economic agents. A very interesting finding of this study is that the relationship between environmental quality and economic progress measured by per capita income can display a wave-like function in the case of water pollution, as opposed to the much dramatized environmental Kuznets curve, with significant policy implications.  相似文献

Since the 1980s Chinese economic reform has greatly accelerated its economic growth while in contrast China's environment is increasingly degraded. The Chinese government has recognized that environmental protection and sustainable economic development can promote mutual and sustainable co-development of the economy and the environment as a basic national principle. This paper examines the interactions between economic development and environmental change in China that were compared and analyzed for the years 1996 and 2000. Net primary production (NPP) was selected as a proxy evaluator of ecosystems and gross domestic product (GDP) was chosen as a proxy evaluator of economic development. An NPP change map was produced with Advanced Very High Resolution Radiometer (AVHRR) summed annual NPP imagery products. The Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime imagery was used to produce a Chinese GDP change map. An integrated map was produced to exhibit the combined changes of NPP and GDP. This map showed that in the regions with increased GDP, NPP decreased but the regions with no GDP change were smaller in area for NPP increase while larger in area for NPP decrease. The changing pattern of NPP varied with the developing level of GDP at province level. A province's development of GDP is controlled by its accessibility to natural resources. Interactions between NPP and GDP are greatly affected by factors of spatial location aside from human factors and natural systems' characteristics.  相似文献

Water markets have featured prominently in the reallocation of water rights to restore freshwater ecosystem health. Incentive-based water rights acquisition and transactions have emerged as a market-oriented policy approach to reallocate water resources from existing uses to enhance the provision, regulation, and sustainability of freshwater ecosystem services. This paper develops a conceptual framework to examine factors enabling and constraining successful policy reform and implementation in market-based environmental water allocation. This analysis distills and extends the findings and lessons of a September 2007 workshop in Brisbane, Australia on environmental water transactions. Two case studies were selected in water stressed basins - the Columbia (U.S.A) and Murray-Darling (Australia) Basins - where transactional approaches to environmental water allocation first emerged. The case studies draw upon practitioner perspectives and previous policy and economic analysis in two regions where shared political economic and physical conditions lend a strong analytical basis for comparison. A common set of policy and regulatory reforms has occurred in both cases - albeit in different forms and via distinct paths - to develop three enabling conditions: (1) establishment of rights to and limits on freshwater extraction and alteration; (2) recognition of the environment as a legitimate water use; and (3) authority to transfer existing water rights to an environmental purpose. However, these elements of policy reform are necessary but not sufficient for effective implementation; a second set of driving forces, barriers, and adaptations explains the ability to achieve larger scale ecological outcomes. These conditions include the physical, social and economic factors driving demand for environmental water allocation; administrative procedures, organizational development and institutional capacity to effect transfers; and adaptive mechanisms to overcome legal, cultural, economic, and environmental barriers. The case study analysis suggests that environmental water transactions can play an important role in establishing environmental water allocations, although water markets require ongoing institutional capacity and adaptive governance. The conceptual framework and empirical lessons generated through this cross-case comparison provide the basis for an expanded research agenda to evaluate the design and performance of market-oriented reforms as implementation experience accrues and new programs emerge in diverse ecological and political economic settings.  相似文献

This paper presents an input-orientated data envelopment analysis (DEA) framework which allows the measurement and decomposition of economic, environmental and ecological efficiency levels in agricultural production across different countries. Economic, environmental and ecological optimisations search for optimal input combinations that minimise total costs, total amount of nutrients, and total amount of cumulative exergy contained in inputs respectively. The application of the framework to an agricultural dataset of 30 OECD countries revealed that (i) there was significant scope to make their agricultural production systems more environmentally and ecologically sustainable; (ii) the improvement in the environmental and ecological sustainability could be achieved by being more technically efficient and, even more significantly, by changing the input combinations; (iii) the rankings of sustainability varied significantly across OECD countries within frontier-based environmental and ecological efficiency measures and between frontier-based measures and indicators.  相似文献

Health expenditures comprise a large part of national incomes, which explains the growing interest of government agencies in establishing efficient control and management policies in the current context of economic difficulties. One of the main problems in efficiency analysis is to determine the environmental variables that have an impact on the production process. In particular, employing data on the European and Central Asian health systems, the article demonstrates that bias corrected Data Envelopment Analysis is most appropriate measuring efficiency than traditional Data Envelopment Analysis. Bias correction, implies a higher potential resources reduction, affects the ranking of health systems and allows variables influencing efficiency which would be undiscovered with non-corrected estimation. The second stage determines that lifestyle factors, policy organization and location of countries affect the efficiency results and cause differences among the countries. The contribution of these results is particularly useful facing the decision making by governments. Their strategies should be oriented to implementing active policies to struggle against smoking and promoting health policies aimed at increasing the level of immunization in order to be more effective improving management efficiency.  相似文献
