长江经济带产业融合水平评价及空间变异分析

Evaluation of the Level of Industrial Integration and Analysis of Spatial Variation in the Yangtze River Economic Belt

从六个维度解析了产业融合并构建评价指标体系,通过赫芬达尔指数法测算出长江经济带各省市2010-2019年产业融合水平,并运用空间自相关分析其空间演化特征。研究结果表明:长江经济带总体呈中高度产业融合,融合水平不断上升,整体融合潜力巨大;区域差距明显,主要集中在几个热点区域;存在显著空间正相关,并呈空间扩散趋势,但空间溢出效应尚不明显。据此提出建议:发挥国家战略优势,提升产业融合效率;三大效益均衡发力,加强产业融合效果;因地制宜对症下药,缩小产业融合差异。

Based on the six dimensions,this paper analyzes the industrial integration and constructs the evaluation index system,measures the level of industrial integration in the provinces and cities of the Yangtze River Economic Belt from 2010 to 2019 by the Heffendahl index method,and analyzes its spatial evolution characteristics by using spatial self-correlation.The results show that:on the whole,the Yangtze River Economic Belt shows medium and high industrial integration,and the integration level is rising,but the overall integration potential is huge;the regional gap is obvious,mainly concentrated in several hot spots;there is a significant spatial positive correlation and a spatial diffusion trend,but the spatial spillover effect is not obvious.Based on this,it is suggested to give full play to the national strategic advantages and improve the efficiency of industrial integration,balance the three benefits and strengthen the effect of industrial integration,suit measures to local conditions and narrow the differences in industrial integration.
