结构调整与技术进步对碳排放影响的空间效应分析

对1997～2012年中国分省域碳排放的数据进行详细测算,发现碳排放具有明显的空间相关性。利用空间面板数据模型分析发现,单位国内生产总值（GDP）能耗和能源结构碳强度对碳排放的影响较为突出。通过检验发现建立空间杜宾模型是最优的。结论：进一步加快产业结构优化升级,培育优势创新产业集群,推广清洁技术的利用,改善以煤炭为主不合理的一次能源消费结构,并充分考虑区域间的集聚效应,在碳减排活动中充分加强区域协作。     

欧盟公共与私营电子采购标准化要求异同初探

电子采购的兴起,逐渐革新了传统的采购模式,大大地提高了效率,节约了成本。欧盟是电子采购制度建设较早的地区之一,且渗透到私营和公共采购领域。为了提高公共与私营电子采购之间的兼容性,2005年2月欧洲标准化委员会（CEN）正式发布了《欧盟电子采购标准化要求和差距分析》（CWA15236）。文章将根据《欧盟电子采购标准化要求和差距分析》（cwA15236）,以现有的法律、标准规范和技术为基础,分析欧盟公共与私营电子采购在法律层面、程序层面和技术层面的主要异同点,同时提出了相关建议。     

全球化对城市空间结构的作用机制分析

论文认为城市空间结构的演进归根结底是微观经济主体,尤其是企业的生产行为和区位选择行为推动的.企业对生产组织和空间布局的不同选择,直接影响着两种不同的空间发展模式——集中化和分散化.全球化和信息化推动了生产技术方式和生产组织方式的演进,对企业区位选择、产业的空间布局,以及城市空间结构和空间组织产生了重要影响,都市圈、城市群成为当今先进生产组织方式的重要空间载体.     

Industry risk transmission channels and the spillover effects of specific determinants in China’s stock market: A spatial econometrics approach

This paper uses a spatial econometrics approach to study the industry risks in China’s stock market. We comprehensively consider the real linkage and information risk transmission channels and analyze the risk spillovers of specific determinants. Our empirical results show the following: 1) The real linkage channel and information channel are both effective transmission channels for driving spillover effects, and the information channel is of the utmost importance. 2) The spillover effects of specific determinants exist and are persistent. The superposition of spillover effects may lead to extreme risk. 3) The transmission channels and spillover effects are asymmetric in different regimes.     

Raising the bar (4)

This editorial summarizes and comments on the papers published in issue 11(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with common factors and spatial dependence in the error term specification of a production function model. The second paper sets forth a New Economic Geography (NEG) model with production activities that vary in their complexity, so as to analyse the impact on specialization patterns across different regions. The third paper measures the efficiency of local public investments using a relatively unknown econometric technique in which the time span over which the variables in the regression equation are measured is increased by one time period every run. The fourth paper adopts a conditional quantile regression approach to determine the impact of people employed in informal jobs on the wage distribution in Colombia and five of its regions. Finally, the last paper proposes and tests two new Bayesian variable selection approaches for spatial econometric models.
