文章根据长江三角经济区25市1996-2014年宏观统计数据,基于地理空间和经济空间权重矩阵构建空间滞后模型与空间误差模型,探讨研究区三大产业的β收敛性动态变化特征,结果表明:研究区第一产业不存在空间相关性和收敛性;在地理和经济距离影响下,研究区内二、三产业呈现绝对β收敛,而第三产业收敛速度高于第二产业,其中科技、劳动力和资本要素显著影响第二产业的收敛性;经济空间权重矩阵前提下第三产业的空间相关性远高于地理空间权重矩阵;基于上述研究结果,发现忽略空间权重矩阵下产业结构收敛性差异将导致区域发展研究误差,区域经济发展战略的制定应以不同空间权重模型下产业结构收敛性研究为基础,加强区域经济合作,促进区域产业协调和经济一体化。
According to the macroscopic statistical data of 25 cities in the Yangtze River Delta from 1996 to 2014, this paper constructs the spatial lag model and spatial error model based on geospatial and economic spatial weight matrix to explore the dynamic characteristics of β convergence of the three industries in the study area. The results show that: There is no spatial correlation and convergence in the primary industry in the study area; under the influence of geographical and economic distance, the secondary and tertiary industries in the study area show absolute β convergence, while the tertiary industry converges faster than the secondary industry. Among them, science and technology, labor force And the capital factor significantly affect the convergence of the secondary industry. The spatial correlation of the tertiary industry under the economic spatial weight matrix is much higher than that of the geospatial weight matrix. Based on the above results, it is found that the convergence of industrial structure ignoring the spatial weight matrix Leading to research errors in regional development. The formulation of regional economic development strategy should be based on the study of convergence of industrial structure under different spatial weights model, strengthen regional economic cooperation and promote regional industrial coordination and economic integration.
