摘要
以长三角地区三省一市307个县域行政单元为研究对象,采用探索性空间分析方法研究2010-2018年长三角地区经济发展水平的时空演化过程,并利用多尺度地理加权回归模型对影响因素进行分析。研究结果显示:长三角地区经济发展放缓且发展不平衡加剧;长三角地区经济集聚趋势平稳但极化现象显著;外资直接投资、二产从业人口占比、三产从业人口占比、固定资产投资、从业人口等因素对长三角地区经济发展产生显著影响,其中资本要素对区域经济发展贡献最大;投入产出高效地带与经济发展高值聚集区间基本吻合。
Taking 307 county administrative units of three provinces and one city in Yangtze River Delta as the research object,this paper uses exploratory spatial analysis method to study the spatial-temporal evolution process of economic development level in Yangtze River Delta from 2010 to 2018,and uses multi-scale geographically weighted regression model to analyze the influencing factors.The results show that:The economic development of the Yangtze River Delta is slowing down and the imbalance of development is aggravating;The trend of economic agglomeration in Yangtze River Delta is stable,but the polarization phenomenon is significant;Foreign direct investment,the proportion of employees in the secondary industry,the proportion of employees in the tertiary industry,fixed asset in-vestment and employees have a significant impact on the economic development of the Yangtze River Delta,in which the capital factor contributes the most to the regional economic development;The high efficiency zone of input and output is basically consistent with the high value cluster zone of economic development.
