摘要
以甘肃省县域经济体为研究对象,将其划分为陇中、陇东、陇南、河西、民族经济区五大分区,基于对县域经济发展指数的测度,运用基尼系数、泰尔指数和极化指数模型,对2006-2015年甘肃省县域经济差异变化和空间极化情况进行实证研究。结果表明:甘肃省县域经济发展差异与空间极化伴随着"缩小—扩大—缩小"的波动演化态势,第二产业、第三产业与区域内差异是导致县域经济差异变化的关键因素,并且产业结构效应与产业集中效应的影响效力较强,而县域经济发展极化现象主要表现为显著增强的五大区域之间的空间极化效应。
The research of this paper takes the county economy of Gansu Province as the research object and divides it into five economic zones:central Gansu,eastern Gansu,southern Gansu,Hexi and ethnic economy.Based on the measurement of the county economic development index,an empirical study on the city economic changes and spatial polarization in Gansu Province from 2006 to 2015 is conducted by using the Gini coefficient,the Theil index and the polarization index.The findings show that the differences in county economic development and spatial polarization in Gansu Province are accompanied by the fluctuant evolution of“shrinking-expanding-shrinking”.The secondary industry,the tertiary industry and the differences within each zone are the key factors leading to the change of the county economy differences.The industrial structure effect and industrial concentration effect are comparatively stronger,while the polarization of county economic development is mainly manifested by the remarkably increased spatial polarization effect among the five zones.
