The accounting method and application of CO2 emissions responsibility by the electricity sector at the provincial level in China

When accounting the CO₂ emissions responsibility of the electricity sector at the provincial level in China,it is of great significance to consider the scope of both producers’ and the consumers’ responsibility,since this will promote fairness in defining emission responsibility and enhance cooperation in emission reduction among provinces.This paper proposes a new method for calculating carbon emissions from the power sector at the provincial level based on the shared responsibility principle and taking into account interregional power exchange.This method can not only be used to account the emission responsibility shared by both the electricity production side and the consumption side,but it is also applicable for calculating the corresponding emission responsibility undertaken by those provinces with net electricity outflow and inflow.This method has been used to account for the carbon emissions responsibilities of the power sector at the provincial level in China since 2011.The empirical results indicate that compared with the production-based accounting method,the carbon emissions of major power-generation provinces in China calculated by the shared responsibility accounting method are reduced by at least 10%,but those of other power-consumption provinces are increased by 20% or more.Secondly,based on the principle of shared responsibility accounting,Inner Mongolia has the highest carbon emissions from the power sector while Hainan has the lowest.Thirdly,four provinces,including Inner Mongolia,Shanxi,Hubei and Anhui,have the highest carbon emissions from net electricity outflow- 14 million t in 2011,accounting for 74.42% of total carbon emissions from net electricity outflow in China.Six provinces,including Hebei,Beijing,Guangdong,Liaoning,Shandong,and Jiangsu,have the highest carbon emissions from net electricity inflow- 11 million t in 2011,accounting for 71.44% of total carbon emissions from net electricity inflow in China.Lastly,this paper has estimated the emission factors of electricity consumption at the provincial level,which can avoid repeated calculations when accounting the emission responsibility of power consumption terminals（e.g.construction,automobile manufacturing and other industries）.In addition,these emission factors can also be used to account the emission responsibilities of provincial power grids.

The channels of the effect of government expenditure on the environment: evidence using dynamic panel data

This paper explores the relationship between government spending and environmental quality using panel data for 94 countries for the period 1970–2008. We identify and estimate three distinct channels that comprise the total direct effect of government expenditure on air pollution, namely a marginal effect, an effect conditional on economic growth and an effect conditional on institutional quality. Since adjustment rate of emissions to their equilibrium level is slow due to technological and institutional reasons, we explicitly take into account dynamics by applying appropriate econometric methods. The results demonstrate that there is a significant alleviating direct effect of government expenditure on SO₂ and NO_x emissions, which increases with the level of economic growth and democracy. However, there is no evidence of a significant effect on pollutants with more global impact on the environment and human health, like N₂O and CO₂, implying that the adoption of international environmental treaties is required in this case.     

Local government,political decentralisation and resilience to natural hazard-associated disasters

Natural hazards affect development and can cause significant and long-term suffering for those affected. Research has shown that sustained long-term disaster preparedness combined with appropriate response and recovery are needed to deliver effective risk reductions. However, as the newly agreed Sendai framework recognises, this knowledge has not been translated into action. This research aims to contribute to our understanding of how to deliver longer term and sustained risk reduction by evaluating the role of political decentralisation in disaster outcomes. Specifically, we investigate whether countries which devolve power to the local level experience reduced numbers of people affected by storms and earthquakes, and have lower economic damage. Using regression analysis and cross-country data from 1950 to 2006, we find that, in relation to both storms and earthquakes, greater transfers of political power to subnational tiers of government reduce hazard impacts on the population. The downside is that more politically decentralised countries, which are usually wealthier countries, can increase the direct economic losses associated with a natural hazard impact after the storm or earthquake than those which are more centralised. However, overall, it seems advantageous to give subnational governments more authority and autonomy in storm and earthquake risk planning.     

政府主导、人口流动与城乡收入差距

中国经济增长具有典型的政府主导特征,通过构造一个包含城镇和农村经济产出的社会福利函数来分析政府主导型经济增长对城乡收入差距的影响关系,并基于中国城镇化发展实际分析了人口流动对城乡收入差距的影响,在此基础上提出研究假说,统计中国1997—2014年省际面板数据,采用泰尔指数测度城乡收入差距并分别进行静态和动态回归分析与检验。静态研究发现政府主导和人口流动显著地拉大了城乡收入差距,但是二者的交互项对城乡收入差距的确具有收敛效应,即随着人口流动的增加,政府主导对城乡收入差距的边际贡献会降低,同样随着政府主导的提升也会降低人口流动对城乡收入差距的边际贡献,这种影响关系在分区域的回归中依然成立,并通过了稳健性检验;动态研究发现全国和分区域中城乡收入差距的变动存在显著的正向路径依赖特征,全国层面政府主导显著地拉大了城乡收入差距,而人口流动及其与政府主导的交互项则显著地缩小了城乡收入差距,但分区域来看政府主导和人口流动对城乡收入差距的影响存在显著的区域异质性,并通过了稳健性检验。因此缩小城乡收入差距不应设置单一的政策目标,需要建立多方面的政策配套体系,逐步矫正政府主导型经济中造成的政府职能异化,精准识别地方财政收支量的规模和结构条件,扩大涉农业务投资的规模,激活农村经济发展活力;在城乡户籍制度改革中进一步打破城乡分割藩篱,大力发展非农产业,增加农民的非农就业机会,促进农民的非农化就业和城镇化迁移,提升城镇化发展质量;最终通过一系列的配套性制度安排,旨在加强支持农业发展和农村建设,促进农民收入增长的制度供给,实现城乡共享发展。     

The science of corporate social responsibility (CSR): Contamination and conflict in a mining project in the southern Ecuadorian Andes

In this article, I explain the role that scientific studies play in shaping collaboration and conflict over mining exploration in the Ecuadorian highlands. Toronto-based IAMGOLD conducted water quality studies to simultaneously fulfill legal obligations and secure support for drilling in an environmentally sensitive zone. With these studies, IAMGOLD generated collaborative relations with local authorities and university scientists. However, water quality studies were also used by dairy farmers to establish new connections for an opposition movement. The scientific studies enabled IAMGOLD and the dairy farmers to make competing claims about the responsibility for contamination of an important watershed. This article analyzes the conflict that resulted and challenges conventional wisdom that distinguishes a corporation's legal obligations from its voluntary CSR programs.     

德国环境设备责任制度初探

德国《民法典》确定了一般环境侵权的规则——行为责任,再以《环境责任法》确立了特殊的环境侵权的规则——设备责任。设备侵权是危险责任的一种,其构成要件有两个:设备运营对环境产生不良影响进而导致损害;人身、财产受侵害。设备责任的承担不要求设备运营人的过错。设备责任归责采用因果关系推定原则。     

交叉上市公司社会责任缺陷披露的市场反应——基于紫金矿业突发渗漏环保事故的案例研究

伴随着工业化进程加快,社会责任缺失现象日益严重,各类企业违法违规事故层出不穷,其中不乏国有大型控股公司,这种现象引起了投资者、监管机构等利益相关者的广泛关注。在此背景下,研究资本市场对上市公司社会责任缺陷披露的反应具有重要的理论意义和现实意义。本文以交叉上市的紫金矿业为例,采用事项研究法,检验了A股和H股市场对紫金矿业集团股份有限公司发布的一系列有关紫金山铜矿湿法厂污水池突发渗漏环保事故重要公告的市场反应,并比较了两地市场对同一公告的反应差异。研究发现:两地市场对重大事故公告均提前预知并呈负面反应,在公告前A股市场反应程度大于H股市场,公告发布后H股市场投资者更加敏感;两地市场对董事会(临时)决议公告呈正面反应,但H股市场投资者更加谨慎;对处罚公告两市反应不同,A股市场未对处罚公告作出反应,H股市场对处罚公告呈负面反应;总体而言,H股市场与A股市场反应程度存在显著差异。     

可持续转型与延伸生产者责任制度

本文采用多层次转型理论的分析框架,回顾了国内外延伸生产者责任(EPR)制度的理论和实践进展,对比了EPR制度倡导者最初提出的创新导向的制度设计,与当前各国实践中基于成本—效益平衡所开展的政策评估研究,指出两者在是否应该将激进的可持续转型作为EPR基本政策目标上观点不同,其原因在于政策的技术创新激励效果难以通过可测量的政策评估方法进行有效考察,由此造成两者在EPR政策调整方向上的分歧:前者坚持EPR制度设计应该进一步完善个体责任原则,以激励生产者创新和采纳绿色技术,推进生产消费模式的系统转型;而后者则强调在现有管制框架下简化制度设计,重点完善循环处理基础设施及其管理效率。这种分歧不仅影响到发达国家EPR制度的演化,也深刻影响了发展中国家EPR制度的移植和建构。结论以中国电子废物管理实践为例,提出构建包含三个层次的演化经济学分析框架,考察EPR制度建构过程中,微观层次的企业技术选择,中观层次的供应链治理结构变动,和宏观层次的再生资源产业转型,以系统考察制度发展对技术创新的激励效果。     

Building the role of local government authorities towards the achievement of the human right to water in rural Tanzania

In recent decades, many changes have occurred in the approach to financing and operating water services in developing countries. The demand‐responsive approach is now adopted in many countries in a context of donor‐supported decentralization processes, which gives more responsibility to end users. However, the government's responsibility at different levels is enforced by the international recognition of the human right to water. This paper examines specific actions that build the role of local government authorities in this scenario. A collaboration between an international NGO and a rural district in Tanzania from 2006 to 2009 is used as an action research case study that is representative of local capacity‐building needs in decentralized contexts and rural areas. Three main challenges were detected: i) lack of reliable information; ii) poor allocation of resources in terms of equity; and iii) lack of long‐term community management support from the district. Two mechanisms were established: i) water point mapping as a tool for information and planning; and ii) a District Water and Sanitation Unit Support (DWUS) for community management. The results show how the framework provided by the goal of human right to water helps to define useful strategies for equity‐oriented planning and post‐project support at the local level.
