南京都市圈产业效率演化及空间差异分析

The Industrial Efficiency Evolution and Spatial Difference of Nanjing Metropolitan Area

都市圈是具有经济一体化趋势的地域空间组织形式,其内部产业效率状态是城市之间存在紧密联系的基础。本文采用数据包络分析(DEA)方法,对南京都市圈内六市四县以及巢湖市市区的产业效率进行分析和空间刻画,结果表明:南京都市圈内产业效率的市域差异,呈现由"中心式结构"向"双核式结构"的过渡趋势,整体产业效率走向相对均衡发展,其中产业效率呈现"东高西低、南高北低"的状态;南京都市圈整体产业效率演化状态趋于增长,其中第二产业的产业效率演化在整个过程中处于主导地位;南京都市圈内的产业效率与其经济实力存在强正相关,经济实力时空格局与南京都市圈产业效率演变的格局基本一致。

In recent years, the problem of circle of the metropolis industry development gradually become an important strategic issue to provincial decision-making and social concern. Based on the data envelopment analysis （DEA） method, we calculate and de-scrible the industry efficiency of nanjing metropolitan circle among six cities and four counties including chaohu city. The results show that： the regional difference of the effi-ciency of the industryof the nanjing metropolitan circle, presents the change from＆quot;central structure＆quot; to ＆quot;dual-core structure＆quot;, towards balanced development. The whole evolution state of industry efficiency of Nanjing metropolitan circle tends to grow, Above all, the industry efficiency of the second industry in the process evolution is in the leading posi-tion. The industry efficiency of Nanjing metropolitan circle have close relations with its economic power, the arrangement of economic strength is consistent with the industrial evolutional basic pattern of Nanjing metropolitan circle, but at the same time because of the influence of factors such as geographical location, it also has some differences.
