浙江省县域经济差异的空间统计分析

Spatial Statistical Analysis on the Variability of County Economies in Zhejiang Province

以浙江省58个县域单元为研究对象,综合采用多指标因子分析、频率分析、空间自相关分析等方法,对县域经济进行总体评价,并进行空间差异的分析和解释。浙江县域经济实力得分的频数分布呈正偏态,说明得分较低的县(市)占据多数,岱山的经济实力名列第一位。将全省县域划分为8种不同类型的经济发展单元,其中欠发达型县域最多,约占48%;从大区域的分布来看,浙东北的县域整体发展水平较高,以稳定的和上升的发达型为主,金丽衢地区则以上升的欠发达型为主,温台沿海稳定的欠发达型占多数;各县域之间存在一定的正相关性,全省经济格局从西南向东北呈现"3+1"的空间格局;县域经济发展存在空间异质性。

An overall evaluation of the county economy is carried for the 58 counties in Zhejiang, using a combination of factor analysis, frequency analysis, spatial autocorrelation analysis and other methods, the spatial a- nalysis and interpretation are also involved. The results showed that： （1） The frequency distribution of scores of the county economic strength in Zhejiang was positively skewed, indicating that the majority of counties get lower scores; Daishan is the first in economic strength among the 58 county units. （2） All county units are divided into 8 different types of economic development units. Underdeveloped type occupies the most, accounting for approximate- ly 48% ; As for the distribution from a large area, The overall level of development in the northeast in Zhejiang is higher. Most of them are stable and moderately developed type, the type of increasing less developed is the most in the district of Jin-Li-Qu. The majority of counties in Wen-Tai belongs to the type of less developed. （3） The Global Moran＇ s I of Zhejiang county economies indicates that a positive correlation exists between the counties. The eoun- ty＇s economic structure shows ＂3 ＋ 1＂ space pattern .（4） Local Moran＇ s I results reflect spatial heterogeneity of county economic development in Zhejiang Province , that is, hollow and salient point spots, the former such as Chun＇ an, Shengzhou, Jiande ; the latter, such as Yiwu City.
