基于区域和行业的视角,本文利用基尼系数分析高技术产业空间差异及其来源问题,运用三种极化指数测度两极化及多极化变化趋势,采用σ收敛、β收敛和俱乐部收敛方法探讨收敛性问题。研究结果表明:中国高技术产业发展的空间差异呈下降趋势,差异主要来自于地区间差异,从区域和行业看,西部的差异程度大于东中部,航空航天器制造业和电子计算机及办公设备制造业的差异程度大于其他行业;大部分行业的两极化特征消失,取而代之的是多极化分布特征,且地区间的差异程度普遍大于地区内;中国高技术产业总体存在σ收敛和β收敛,区域和行业还存在俱乐部收敛特征,但导致其收敛的影响因素并不一致。
Based on regional and industry perspectives, this paper analyzes the spatial heterogeneity of high-tech industries and their origins using the Gini coefficient. By using three kinds of polarization indices to measure the trend of polarization and multi-polarization, this paper uses the convergence of σ, convergence of β and convergence of clubs to explore convergence Sexual issues. The results show that: the spatial difference of high-tech industry in China shows a downward trend, the difference mainly comes from the interregional differences. In terms of regions and industries, the difference in the west is greater than that in the east, the manufacturing of aerospace vehicles, the manufacture of electronic computers and office equipment The degree of industry difference is greater than that of other industries; the polarization characteristics of most industries disappear, and the characteristics of multi-polarization are replaced by them, and the degree of regional differences is generally greater than that of regions; the overall high-tech industry in China has σ convergence and β convergence, And the industry still has the characteristics of club convergence, but the factors that lead to its convergence are not the same.
