碳中和愿景的实现路径与政策体系

习近平主席在第七十五届联合国大会上郑重承诺中国将努力争取2060年实现碳中和目标，为中国未来低碳转型促进经济高质量发展、生态文明建设指明了方向、明确了目标，也提振了全球应对气候变化的信心。作为排放量全球最大的发展中国家，在2030年前达峰后用三十年左右的时间很快地实现碳中和愿景，任务异常艰巨，但总体上排放路径必然呈现尽早达峰、稳中有降、快速降低、趋稳中和的过程。支撑碳中和的技术几乎涉及所有的产业和经济活动，从控制碳排放途径的角度可以分为高能效循环利用技术、零碳能源技术、负排放技术。政府、企业、个人在迈向碳中和愿景进程中具有至关重要而又各有侧重的作用，需要科学的政策体系以形成系统有效的激励机制，促进资本和人才朝着碳中和技术创新和市场化推广应用方向快速汇集。

The idea of sustainable development

In this lecture, I demonstrate how very different macroeconomic history begins to look if Nature is included as a capital asset in production activities. The tentative conclusions I draw from the evidence are: (1) high population growth in the world’s poorest regions (South Asia and sub-Saharan Africa) has been an obstacle to the achievement of sustainable economic development there; relatedly, (2) when population growth is taken into account, the accumulation of manufactured capital, knowledge, and human capital (health and education) has not compensated for the degradation of natural capital in South Asia and sub-Saharan Africa and, in all probability, even in the UK and the US; (3) China is possibly an exception to (1) and (2). This article is based on the Keynote Lecture delivered at the international symposium on “Sustainability in an Unequal World”, held in Tokyo on November 24, 2006. The exposition relies on my book, Economics: A Very Short Introduction, Oxford University Press, Oxford, 2007. The author is the Frank Ramsey Professor of Economics at the University of Cambridge and a Fellow of St. John’s College, Cambridge.     

过江通道建设对相对落后地区发展的影响——以江苏省南通市为例

苏通大桥及沪崇苏通道的建设将引致区域交通格局的演化,从而对相关地区经济社会发展产生深远影响。对于相对落后的南通市而言,快速过江通道建设既是促进发展的良好机遇,同时也将带来新的挑战和威胁：（1）交通可达性改善明显,南向联系趋于便捷,运输成本相应减小,要素集聚呈现加速态势,但优质要素面临流失威胁;（2）产业规模迅速扩张,但以低层次产业为主,进一步加大了产业层次提升的压力,同时建设用地的盲目扩张和散乱布局,使得空间开发无序风险加剧;（3）进入上海都市圈的紧密圈层,有望成为长江三角洲北翼重要的次中心城市,但面临的竞争压力也不断增大。为促进南通市的可持续发展,政府部门应在推进都市区建设、促进要素集聚、空间资源的合理和统筹利用等方面制定科学有效的区域政策。     

特大型城市客运交通碳排放与减排对策研究

本文基于对现有城市交通碳排放测算方法的比较分析,以上海市为例,采用IPCC"自下而上"法对特大型城市客运交通CO2排放进行了测算,结果显示:轨道交通是碳排放效率最高的客运方式,出租车最低;客运交通CO2排放总量增长迅速,且碳源结构发生了较大变化;近年客运交通CO2排放增量主要来自私人载客汽车,同时公务交通在客运交通碳排放中始终占较大比重。由此本文认为,控制客运交通碳排放的关键在于对以私人载客汽车和单位载客汽车为主的个体交通的管理和控制,形成以公共交通为主的交通结构。在此基础上,为了将控制碳排放纳入到城市交通政策目标中去,本文就主要城市交通政策对客运交通碳排放产生的影响进行了深入分析,并得出结论:以往的交通供给、需求管理政策对于抑制客运交通碳排放增长的作用有限;而就目前城市空间发展政策的实施效果而言,也不利于降低居民出行的碳排放水平。文章最后分别从交通供给、需求管理以及城市空间角度给出了控制客运交通碳排放的对策。     

完善我国医疗废物集中处置收费政策的思考和建议

医疗废物处置收费政策是医疗废物处置产业化发展的重要前提和保障。当前,医疗废物处置收费政策执行难,欠费、漏费等问题非常突出,医疗废物集中收集十分困难。在对我国医疗废物处置收费政策进行全面分析和评估的基础上,对当前收费政策存在的主要问题和产生的原因进行了分析。以加快完善医疗废物处置收费政策为目标,从完善政策体系、加强监管执法、提高标准合理性、综合确定费用承担方、制定鼓励性的经济政策、提高宣传和缴费意识等方面,提出医疗废物处置收费政策改革完善的若干建议。     

Australia and Russia: How do their environmental policy processes differ?

This paper focuses on comparative review and analysis of the systems of environmental protection, national environmental strategies and fundamentals of environmental legislation in Australia and the Russian Federation. These countries have many socioeconomic similarities, such as low population densities and richness in natural resources which are largely exported. The main disparity between Australia and Russia is in the types of economy. This paper ‘continues’ the sequence of recent scholarly publications on comparison of various features of environmental policies in the countries from all over the world. Comparative analysis in this research has been based on examination of scholarly publications, legislation, government documents, mass media sources and NGO responses. The analysis has revealed a number of differences including top-down implementation of policies in Russia whereas in Australia, each State (Territory) implements policies with significant independence from the Commonwealth Government. At the same time, similarities between the countries have been identified: for example, in deficits in the budget of local environmental authorities and in the presence of contradictions in legislation at national and regional levels of government. Suggestions resulting from this analysis include further integration of sustainable development strategies at all levels of Australian government to encourage further protection of the environment and, for Russia, creating a separate Ministry of Environmental Protection. These approaches should assist facilitation of sustainable development for both nations.

人口流动规律及其政策含义

人口流动是人力资源配轩优化的根本创新路径,人口流动的一般规律是:如果流动人口为理性行为选择者,在社会制度安排许可的发展环境下,当不同区域和不同产业间形成比较收益差异,存在着流动收益大于流动成本的潜在和现实的各种获利机会时,就必定驱使人们由低收益领域向高必益领域流动,而且比较收益差异量与流动人口的流速、流量正相关,并必然导致产生收益率及人口分布走向平均化的趋势,社会发展也将获得最优化的人力资源配置结果.其相关政策含义:一是人口流动是流动人口的理性选择;二是切实保障公民的自由流动权利;三是利用比较利益差别促进人口流动;四是降低各种不必要的流动成本和流动风险;五是建构人口流动的有效率社会发展框架.     

农业贸易政策环境影响评价的案例研究

随着国际贸易自由化程度的提高,贸易与环境问题越来越引起人们的重视。对贸易政策进行环境影响评价。指导贸易政策的制定。是解决贸易所带来的环境问题的重要途径。了解中国入世后一系列的农业政策调整会在多大程度上影响环境。对于新的政策决策具有指导意义。本文在总结贸易政策环境影响评价研究步骤和方法的基础上。对农业贸易政策环境影响评价的特点进行讨论,并以河北省迁安市小麦种植业为例,进行农业贸易政策环境影响评价的案例研究。由于农业贸易政策直接作用于农业生产经营活动。再通过农业生产经营等活动间接地影响环境质量状况。本文借助转移矩阵方法进行分析评价。     

The Clean Development Mechanism and Sustainable Development in China''''s Electricity Sector

1 INTRODUCTIONEnergy and environmental issues in China have receivedsignificant attention in both the peer-reviewed literatureand in international energy and environmental policymaking in the last number of years. China's coal dominatedenergy consumption results in significant regional pollutionproblems, most notably acid rain that affects nearly 1/3rdof China's landmass and air pollution that plagues manyof its major cities. China now ranks as the top emitterof sulphur dioxide (SO2) pol…
