湖南省县域经济差异的时空演变及其影响因素
Spatio-temporal evolution of county economic differences in Hunan Province and its influencing factors
摘要
Abstract
To clarify the county economic differences in Hunan Province and their causes,the economic development level was measured by the entropy weight method,and the spatio-temporal evolution characteristics of county economic differences in Hunan Province from 2005 to 2020 were studied by the methods such as weighted coefficient of variation,Theil coeffi-cient,Moran index,and Getis-Ord G*i index,and the causes of these differences were analyzed using the geographical detector.The results show that:① The absolute and relative differences of county economies in Hunan Province have both decreased,and the regional differences are in a converging state;the economic differences mainly come from intra-regional differences.② The spatial agglomeration of county economic development in Hunan Province has been increasing year by year,and the number of cold spots in county economy has increased,showing the spatial distribution pattern of"hot in the east and cold in the west".③ The main factors influencing the level of county economic development in Hunan Province are per capita local financial income,urbanization rate of population,market size,economic foundatio,and the proportion of the secondary industry;all factors show interaction enhancing effect,seven factors including road density,foreign investment strength,terrain undulation degree,proportion of the tertiary industry,fixed asset investment strength,domestic investment strength,and the per capita local financial expenditure show significant nonlinear enhancement in the interactive detection,although having less influences in factor detection.关键词
