产业环境准入的国内外研究进展

环境准入被认为是加强源头控制的有效手段，已经得到社会各界广泛认可和高度关注。简要介绍了产业环境准入的基本概念和主要内容，并对国内外的研究现状进行了综述。国外研究主要集中在产业环境准入制度的应用效果评价方面，而国内则主要研究区域、行业、企业（项目）等不同层次的准入门槛，并构建了多种指标体系。在区域层次，重点考虑区域环境容量、环境功能区划等的约束作用；在行业层次，则是在考虑容量约束的条件下，重点考虑我国各行业技术水平、资源消耗强度、污染排放强度等，并确定准入限值；在企业（项目）层次，则是在考虑上述约束条件的前提下，重点考虑选址、技术装备水平等问题。

Industrial Environmental Access and Its Research Progress at Home and Abroad

Environmental access, an effective means to strengthen the source control, has been widely accepted and highly concerned by various circles of society. The concept and main implications of industrial environmental access were introduced, and its research progress at home and abroad reviewed. The foreign research focuses on the application and effectiveness evaluation of the industrial environmental access, while the domestic research mainly focuses on the access thresholds from the levels of region, industry and enterprise (project). Besides, a variety of index systems are also constructed in China. At the regional level, the major considerations are the constraints of regional environmental capacity, environmental function regionalization, etc. At the industry level, the major considerations are the technology level, the resource consumption intensity and pollutant emission intensity based on which the access limits are determined. At the enterprise (project) level, the major considerations are the location, technology and equipment level, etc. in addition to the above constraints.
