Regulatory and environmental effects on public transit efficiency: a mixed DEA-SFA approach

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O. Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies, the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public transit networks.

How efficient are national environmental standards? A benefit-cost analysis of the United States experience

This paper summarizes the results of the first systematic, geographically-specific efficiency assessment of the U.S. experience with national environmental standards and with alternative approaches to establishing those standards. This ex-post evaluation assessed the net benefits that resulted from EPA's regulation of conventional air and water pollutants from the pulp and paper industry between 1973 and 1984. The paper compares the benefit-cost efficiencies of the three dominant regulatory approaches: technology, ambient, and benefits. Unlike previous studies, which assessed benefits and costs on a national basis, the study estimates both costs and benefits on a facility-by-facility basis. The analysis shows how the efficiency of national environmental regulations can vary dramatically at local levels. The authors conclude that the technology-based standards for water pollution management failed as an efficient environmental strategy. The costs clearly exceeded the benefits in the aggregate, as well as in the specific in most situations. Benefits exceeded costs at only 11 of the 68 mills investigated. The ambient based standards for air pollution management succeeded as an environmental strategy in the aggregate, but succeeded in the specific for only one-third of the mills (22 of 60 mills). The benefits-based standards for air pollution management also succeeded in the aggregate as well as in the specific for about one-half of the mills. Benefits exceeded costs at 29 of the 60 mills investigated. The results of the study point to two major conclusions. First, a regulatory policy that is based on some measure of environmental results, either ambient-based or benefits-based, will be more efficient than a policy that ignores environmental results. Second, truly efficient policies for reducing environmental risks require pollution mitigation decisions that take into account local conditions. These include not only the changes in local ambient conditions, but also the number of people who will benefit from pollution reduction decisions. This latter conclusion suggests that national environmental standards per se may be inefficient.Dr. Luken is currently Senior Environmental Advisor to the United Nations Industrial Development Organization (UNIDO) in Vienna, Austria.

环境库兹涅茨曲线假说及其在中国的检验

经济与环境协调发展是我国经济发展中的重大课题。本文从环境库兹涅茨曲线假说出发,利用中国各个省市区1989～2004年数据建立面板数据模型,运用固定效应模型和随机效应模型对其进行估计,以此剖析我国经济增长与环境污染水平的演变规律。结果表明,环境库兹涅茨曲线假说在我国并不成立。因此,我国不能盲目重复发达国家"先污染,后治理"的传统模式,而应该走环境与经济持续协调发展的道路。     

苏联模式影响下的绿地资源管理——从历史 制度主义视角之“路径依赖”解读

历史制度主义是新制度主义中的重要分支，强调政 策是随着时间的推移而被制度塑造的，存在着“路径依赖”现 象，这意味着在过去制度环境中做出的政策选择影响现在的政 策结果。中国城市治理制度深受苏联模式的影响，若想理解以 及应对规划管理中存在的问题，首先需探索其历史。提供了一 种从规划历史切入分析的视角以更好地理解与解决规划管理中 的现存问题，进而构建具有我国发展特色的规划管理理论分析 方法。首先探讨了历史制度主义在制度分析中的应用及优势， 然后通过探讨与分析我国绿地资源管理现状证明苏联模式如何 通过“路径依赖”影响现在的绿地资源管理机制，将历史制度 主义分析方法应用于理解我国的规划管理实践中，在我国自然 资源部成立的改革大背景下提出相应政策建议。     

Idea and goals of environmental protection and ecological construction in the 11^th five-year plan period

In this paper, the executive of the 10th Five- Year Plan in the field of environmental protection and ecological constrution is reviewed, and the charactristics of economic growth and its environmental impact on the 11^th Five-Year Plan is forecasted and analyzed. A principal idea of eavironmental protection and ecological construction is put forward for the 11^th Five-Year Plan pertod： strensgthen the point treatment in key areas and set the main targets based on the idea. The relating countermeasures in national level are proposed as follows： set up appropriate ideas for official achievements by launching resources and environmental cost acconting; adjust the industrial struacture actively by industrial policies and strenuous work; develop circular economy, change the mode of environmental protecgon from end treatment to headstream and proeess control： strengthen the market mechanism in the process of pollution treatment, set up the system of ＂who treats who benefits＂ ; perfect interrelated laws and standards, strengthen the ability of environmental munagement; lay extra emphasis on two key targets： water pollution tretment in key river basins and management of the reserves; and combine the ecological consnuction and poverty alleviation in higher level.

Making green discourses matter in policy-making: Learning from discursive power struggles within the policy area of car taxation

This paper is about stability and change in the policy-making discourse of a traditional neoclassical policy area, the area of car taxation. Stability is here related to the unquestioned continuation of a traditional neoclassical economics perspective in policy-making, whereas change is related to the introduction and impact of environmental concerns. The aim of the paper is to investigate, what makes green discourses matter in traditional policy-making. It is based on an in-depth study of policy-making processes related to car taxation in two environmental front-runner countries, Sweden and Denmark.Making green discourses matter in policy-making is an important contemporary environmental challenge. Therefore, as Tian Shi argues, we need more research into the institutional setting of the policy-making process. Ecological economics as a policy science has to have a broad understanding of the political economic nature of the policy process. Taking this standpoint as the point of departure, the paper seeks to uncover questions such as, what is the policy-making reality in which Swedish and Danish green discourses have to make a difference? How do existing neoclassical regimes react, when green actors attempt to influence policy-making from an environmental point of view? And to what extent can green discourses actually have an impact on the policy world within the area of car taxation?The paper concludes that the traditional neoclassical economic discourse is particularly robust and resistant against alternative green discourses. Stability rather than change is the dominating picture. This does not imply that environmental concerns will not be taken into account in the future. Rather it implies that only the changes, which keep up the existing order, or enhance the narrow power-related interests of the dominating actors, will materialise more or less easily. The rest is a power struggle in which timing, coalition-building, persistence and thorough knowledge about the field in question is of importance. In this struggle change agents will also benefit from the ability to rethink dominating ways of thinking and doing in an environmentally benign way. A rethinking that is based on environmental values while at the same time holding positive visions that are ‘compatible’ with the existing dominating discourse.
