摘要
从双循环新发展格局视角分析产业升级效应,以长江经济带 108 个城市作为研究对象,选取 2003-2022 年数据进行实证分析,结果表明:对外开放与产业升级之间呈倒"U"型关系,区际开放与产业升级呈正相关关系,二重开放能够实现对外开放与区际开放优势互补,从而促进产业升级;基于资源禀赋与经济发展水平差异,二重开放对长江经济带中游地区的产业升级效应最为显著,对外开放与产业升级之间在下游和中游地区呈倒"U"型关系,在上游地区呈"U"型关系,区际开放对产业升级均具有促进作用,呈现由东向西依次减弱的趋势;进一步研究发现,二重开放对产业升级的两个维度均具有促进作用,产业结构高级化在二重开放促进产业升级中的中介作用更强.最后,从统筹协调对外开放与区际开放的关系、综合考虑地区间资源禀赋差异、完善二重开放的协同作用等方面提出建议.
Abstract
This paper analyzes the effect of industrial upgrading from the perspective of the new development pattern of double-cycle,takes 108 cities in the Yangtze River Economic Belt as the research objects,and selects the data from 2003 to 2022 for empirical research,and the results show that there is an inverted"U"relationship between opening up and industrial upgrading,and there is a positive correlation between inter-regional opening and industrial upgrading,and the dual opening up can realize the complementary advantages of opening up and inter-regional opening up,thereby promoting industrial upgrading.Based on the difference between resource endowment and economic development level,the effect of dual opening on the industrial upgrading of the middle reaches of the Yangtze River Economic Belt is the most significant,and the relationship between opening up and industrial upgrading is an inverted"U"shape in the downstream and midstream areas,and a"U"shaped relationship in the upstream areas,and inter-regional opening has a promoting effect on industrial upgrading,showing a trend of weakening from east to west.Further research finds that the dual opening has a promoting effect on both dimensions of industrial upgrading,and the advanced industrial structure plays a stronger intermediary role in the dual opening to promote industrial upgrading.Finally,countermeasures and suggestions are put forward from the aspects of overall planning and coordination of the relationship between opening up and inter-regional opening-up,comprehensive consideration of the differences in resource endowments between regions,and improvement of the synergy of dual opening-up.
