基于TW指数的我国创新极化测度及区域比较研究

Research on China’s Innovation Polarization Measure and Regional Comparison Based on TW Index

创新资源由周边落后地区向经济中心进行集聚运动,从而形成创新极化效应,随着增长极对周边地区的辐射作用显现,极化效应向扩散效应过渡。本文首先在构建创新能力评价指标体系的基础上,运用因子分析法计算得出1998~2017年我国省级区域的创新能力综合得分。其次通过测算TW指数,对我国整体范围及4个经济区域资源极化程度进行了分析。结果表明:我国经济极化指数呈现先增强后减弱的趋势,近年来,虽然我国创新极化程度逐渐减弱,但仍处于较高水平。4个经济区域内的创新极化程度存在明显差异,东西部存在显著的极化现象,中部地区次之,东北地区极化水平最低。我国应针对性地制定区域发展战略,推动跨区域协调合作创新,构建多层次的增长极体系,通过极化效应和扩散效应的共同作用,辐射周边落后地区,促进创新资源的再分配,推动区域经济的平衡合理发展。

Innovative resources are concentrated from the surrounding backward areas to the economic center,thus forming an innovative polarization effect.As the growth poles appear to the surrounding areas,the polarization effect transitions to the diffusion effect.The paper constructs an evaluation index system of innovation ability.On the basis of the calculating the comprehensive scores of innovation ability of 30 provinces(cities,districts)in China,by analyzing the TW index of China and four economic regions from 1998 to 2017,the trend of national innovation polarization is analyzed,and analyze and compare the inter-regional polarization effects of the four economic regions.The results show that China’s economic polarization index shows a trend of first strengthening and then weakening.In recent years,the degree of polarization of innovation in China has gradually weakened,but it is still at a relatively high level,and the gap between regions is obvious.The polarization of innovation polarization in the four economic regions is roughly consistent with the national trend,but there is a significant difference in the degree of polarization of innovation in each region.There is a significant polarization phenomenon in the eastern and western regions,followed by the central region and the lowest in the northeast region.China should formulate regional development strategies in a targeted manner,promote cross-regional coordination and innovation,and build a multi-level growth pole system.Through the combined effects of polarization and diffusion effects,we will radiate surrounding backward areas and promote the redistribution of innovative resources,and promote a balanced and rational development of the regional economy.
