    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、R&D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 Flows Analysis(MFA)is an important tool for efficient resource management policies to relieve the increasing pressure of economic growth on resources and environment. Employing both statistical and econometrics methods such as PCA and super-DEA, this paper tries to compare and analyze the material flows of economic activities in 2013 across China’s 31 provinces, metropolitans and autonomous regions. The result shows that significant and patterned differences exist in material inputs across the regions, especially between Eastern and Western areas. The major influencing factors include population density, per capita material stock, per capita GDP, industrial structure, percentage of R&D investment and mineral resource density, etc. These factors may be classified into three principal components, respectively socio-economic component, two-dimension principle component of the secondary industry ratio and population density and single component of resource endowment. Resource efficiencies in Tianjian, Beijing, Shanghai, Jiangsu and Xinjiang are larger than 1. The 31 provinces, metropolitans and autonomous regions can be divided into four region classifications according to material input intensity and material efficiency.
