The Spatial Correlations and Deviations Evolution Pattern in Jiangsu County Labor Productivity
结合ESDA和GWR方法，分析了江苏县域劳动生产率与影响因素的空间相关性和偏差演化模式，发现南北高-低聚类偏差，且各变量影响存在空间异质性和向北转移趋势。
The present research on the spatial evolution of county level labor productivity has focused less attention to the interaction relationship between the spatial pattern variable and its influencing factors.This paper combined with ESDA and GWR methods as tools to analysis the labor productivity spatial correlations and deviations evolution pattern.The conclusions are summarized as follows:(1) ESDA analysis results show that all variables has a high-low clustering deviation pattern in south and north,and in the overall space each variable has the spatial autocorrelation,except informationalized level has negative correlation with labor productivity,other variables have positive correlation with labor productivity,but the tendency of the related degree is different.(2) The different type areas of labor productivity with variables probably different feature relations structure lead to the spatial location corresponding degree is different.The GWR reveals estimates parameters of samples in different quantile have directivity and numerical size differences,and the fluctuation trend is the same as ESDA detection result along with the evolution of years,which proves the potential spatial correlation and spatial heterogeneity in the features relations.(3) Estimate parameters evolution characteristics of each variable shows,except informationlized level,the marginal effect impact on lab productivity of economic density,government intervention,per fiscal expenditure and outside open degree have transfer situation to north,which means under the spatial correlation,the labor productivity of northern Jiangsu and coastal regions may have a tendency to catch up southern Jiangsu.
