基于面板数据的西江流域经济发展成本差异分析

成本最小化选择是经济决策的基本规则之一,在区域发展布局上亦然。这就需要对不同类型区域的发展成本做比较分析。横贯我国西中东部、跨越南方四省(区)的西江流域在地理环境、发展成本及发展绩效上均呈现出较大的差异性,是进行此类分析的典型样域。基于面板数据的DEA和综合评价分析表明,西江流域不同域段单位产出的内部、外部和综合成本均与其地理梯度成正向关系,亦即流域发展成本大致呈上游>中游>下游的空间差异性和梯度性。此差异可能意味着需重新审视区域协调发展与均衡发展的关系、战略及政策。

Analysis of Economic Development Cost Difference among Reaches of West River based on Panel Datac

The selection of cost minimization is a basic rule of economic policy-making,it is the same as in the regional development layout.It requires comparative analysis on the development cost of different types of regions.The West River which stretches across the eastern,central and western regions of China and spans four southern provinces present a greater difference among geographic conditions,development cost and development performance,so it is the typical sample region on such analysis.The analysis of DEA and comprehensive evaluation,which is based on panel data,shows that the internal,external and comprehensive cost of per unit of output in different districts of the West River have a positive correlation with its geographical gradient.Namely,the river-basin development cost approximately shows a character of spatial difference and gradient that upper reaches is higher than middle reaches and middle reaches is higher than lower reaches.This difference may mean that it needs to survey the relation,strategy and policy of regional coordinated and balanced development again.
