宁夏县域经济的类型演变特征及其发展路径

EVOLUTION CHARACTERISTICS AND DEVELOPMENT TRACTS OF COUNTY ECONOMY IN NINGXIA

对县域经济类型进行划分并对其时空格局演变进行分析是总结县域经济发展模式,制定县域发展政策的重要依据。在对宁夏县域经济发展程度进行划分,以及对其主导产业类型的判定的基础上,将两个判定结果相结合能最终确定县域经济类型。依据此方法对1989—2009年宁夏县域经济类型的演变特征进行分析,结果表明:近20年宁夏县域经济总体上实现了较快的发展;产业类型由单一的农业主导型,逐渐演变为以工业主导型和商贸业主导型为主。总体来讲,有四个类型区的发展路径具有相对一致性,可以分别作为一个政策扶持的类型区。

County economy is open and characteristic economy system which has county town as centre, small towns as links, village as hinterland. Dividing types of county economy and analyzing its temporal and spatial evolution is an important basis for summarizing models of county economic development and making policy. By adopting the method of coefficient of module ratio, this paper divide county economic develop-ment into different levels and judge the leading industry types by calculating the sum of mean and standard deviation of ratio of different industries to total output value. By calculating these data, types of county econ- omy can be ascertained. This paper analyzes evolutional characteristics of county economy in Ningxia from 1994 to 2009 by adopting the method above. It shows that county economy has rapidly developed to a great extent but county development disparities have been expanding also in Ningxia since 1990s. The four coun-ties in Central and Southern Ningxia including in Haiyuan county, Xiji county, Longde county, Jinyuan coun- ty have same development tract. They changed from type of less developed agricultural leading to less devel-oped commercial leading. Now they are still poor areas. The other three counties in Central and Southern Ningxia including in Yanchi county, Tongxin county, Pengyang county have same development model. They are poor areas also but have mineral resources to mine. So their types of county economy are less developed industry leading. The three county including Litong district, Shapotou district, Yuanzhou district have same development characteristics although their degree of development are different. They would have not charac-teristics of county economy and became region economy center and have stronger assemble and diffuse func-tion. Summarizing those development tracts can provide regulation and making policy basis for province and county government.
