针对县域尺度生产率空间演化和影响要素相互作用关系分析的缺乏,综合ESDA和GWR模型研究江苏县域劳动生产率的空间关联和分异演化格局,结论如下:①ESDA探测分析表明,所有变量局部空间上存在高低集聚的南北分异格局,全局空间上具有自相关效应且除政府干预与劳动生产率为负相关外,其他变量均为正向相关关系,但相关程度变化趋势仍有差异;②劳动生产率不同类型区与变量可能的要素关系结构不同导致空间位置上的对应程度不同,基于GWR揭示了不同分布位置样本参数估计值存在方向性和数值大小差异,且随年份演进波动趋势与ESDA探测结果相同,由此验证了要素关系中潜在的空间关联和空间异质性;③各变量回归估计参数的演变特征揭示出,除信息化水平外,经济密度、政府干预、人均国内投资和对外开放程度对劳动生产率边际效应的影响均有往北部转移的态势,隐含着在空间关联效应下,欠发达的苏北和沿海等地劳动生产率或有追赶较发达苏南地区的趋势。
According to the lack of analysis on the spatial evolution of the productivity and the interaction between the influencing factors in the county scale, the ESDA and GWR models are used to study the spatial correlation and differentiation evolution patterns of labor productivity in counties of Jiangsu Province. The conclusions are as follows: ①ESDA detection analysis shows that all variables exist in local space The pattern of agglomeration varies from south to north. There is an autocorrelation effect in the global space and there is a positive correlation with other variables except for government intervention and labor productivity. However, there are still some differences in the trend of correlation degree. (2) Different from the possible structure of the variables, the degree of correspondence in the spatial positions is different. Based on the GWR, the differences in the directionality and numerical value of the estimated values of the samples in different distribution locations are revealed, and the trend of evolution and fluctuation with the years is the same as the ESDA detection result. (3) The evolvement characteristics of the regression estimation parameters of various variables reveal that in addition to the informatization level, the economic density, government intervention, per capita domestic investment and the degree of opening to the outside world on the labor productivity marginal Effects of the impact of the transfer to the north Potential implicit in the spatial correlation effect, less developed northern Jiangsu and other places along the coast to catch up with labor productivity or more developed regions of Da Sunan trend.
