摘要:

经济发展可决定一个地区资源配置的空间分布和发展格局,探究经济发展空间差异及影响因素可为区域发展规划、发展政策制定提供重要参考。以重庆三峡库区生态经济区县域为评价单元,建立经济发展水平指标体系,运用主成分分析法,计算各县域的经济发展水平综合得分值,将其划分为最高、较高、中等、较低和最低5个等级,进而运用多元变量回归分析探究经济发展空间差异的显著影响因素。研究表明:该区经济发展水平具有明显的空间差异性,总体趋势为自西向东逐渐降低。地形、区位及交通3者是造成经济发展空间差异的主要影响因素,在远离重庆主城区、海拔高、坡度大的山区,交通通达性已成为制约县域经济发展的瓶颈因素。因而,要缩小经济发展差距,促进各县域协调发展,应首要解决交通问题

Abstract:

The spatial allocation of resources and regional development pattern are greatly determined by economic development.Researching the spatial difference of economic development and its contributing factors can provide important reference for marking out regional development plan and policy to promote balanced development among different regions.This paper took county in ecological economic zone of Chongqing Three Gorges Reservoir Region as evaluation cell to establish index system,employed the method of principal component analysis to calculate integrated score in each county respectively,and then further put them into five levels.The impact of natural conditions (average latitude and slope),location (the shortest time from county town to central cities of Chongqing),transportation (density of highway network),communication systems (capacities of local telephone exchanges and mobile telephone exchanges) and manpower (population density and number of people receiving college degrees in every 100 thousand persons) on spatial difference of economic development was analyzed through a statistical method,and the determinants in the area were obtained by using stepwise regression model with SPSS 160 software.The results show as follows.(1) In this area,there was significant spatial distribution for economic development, which decreased from west to east.Economic development level of counties lied in southwest and middle of the area was generally higher than that of counties lied in northeast.(2) Natural conditions,location and transportation were the most significant contributing factors of spatial difference of economic development,while the influence of communication systems and manpower was not obvious.Transportation seriously restricted county economic development and was the top priority to narrow economic gap.(3) Compared with southwest,the northeast of this area was mainly made up of mountains and hills with higher elevation and steeper pitch.Because of complicated geographical conditions,weak transportation infrastructure and receiving little economic radiation from central cities of Chongqing,some counties in northeast had fragile ecological environment,unreasonable industrial structure,inadequate development of characteristic industries,low population quality and backward economy.Lastly,this paper simply discussed the related measures on promoting regional coordinated development,including working hard to improve traffic to break the limits of geographic disparities,reinforcing the radiation function of central cities through importing hightech and export processing industries and developing the characteristic agriculture and secondary tertiary industry through exploiting mineral and tourism resources and orienting the farm products to the needs of market
