【摘要】：物质流分析是制定资源高效循环利用政策、克服经济增长与资源环境矛盾的重要工具。利用统计学、主成分分析和超效率DEA分析等方法,对2013年我国31个省市区经济活动的物质流进行系统的比较分析,结果表明:我国物质投入存在明显的有规律的省际和区域差异,东部地区和西部地区间的差异尤其明显;主要影响因素有人口密度、人均物质资源蓄积存量、人均GDP、产业结构、RD投入及矿产资源禀赋强度等,社会经济综合成分、二产比重及人口密度二维成分和资源禀赋单成分是解释其大部分差异的三个主成分;天津、北京、上海、江苏、广东和新疆等省市区的相对物质综合利用效率大于1;根据物质投入强度和物质利用效率,31个省市区可划分为四个类别。
[Abstract]:Material flow analysis is an important tool for making efficient recycling policies of resources and overcoming the contradiction between economic growth and resources and environment.By using the methods of statistics, principal component analysis and super-efficiency DEA analysis, this paper makes a systematic comparative analysis of the material flow of the economic activities of 31 provinces and municipalities in China in 2013.The results show that there are obvious regional and inter-provincial differences in material input in China, especially in the eastern and western regions, and the main influencing factors are population density, per capita material resource accumulation and storage.Per capita GDP, industrial structure, R D input and mineral resource endowment intensity, social and economic composition, two dimensional component of secondary production proportion and population density and single component of resource endowment are the three principal components to explain most of the differences; Tianjin, Beijing, Shanghai,The relative comprehensive utilization efficiency of materials in Jiangsu, Guangdong and Xinjiang provinces is greater than 1. According to the intensity of material input and the efficiency of material utilization, 31 provinces and municipalities can be divided into four categories.
