产品空间结构视角下的产业升级研究——以江苏省装备制造业为例

产业升级的路径由其比较优势演化路径所决定,而产品空间结构能够反映并影响一个国家或地区比较优势、核心竞争力等经济元素的变化。为了明确产业升级的方向路径,文章基于Hausmann等学者提出的产品空间与比较优势演化理论,结合江苏省装备制造业的发展,构建了显示性比较优势、产品邻近度、产品空间密度等指标,深入研究了产品空间结构对比较优势的影响。研究发现,产品邻近度、产品空间密度等指标都能够对显示性比较优势产生影响,即产品空间结构的变化会促使比较优势发生改变,这为确定产业升级方向路径提供了新的视角。最后,文章根据江苏省装备制造业的产品空间结构的状况,提出了如何改变产品空间结构以促进比较优势演化进而实现产业升级的对策建议。

Industrialupgrading from the Perspective of Product Space Structure---A Case Study of Equipment and Manufactureindustry of Jiangsu

The path of industrial upgrading is determined by its comparative advantage evolution path,and the product space structure can reflect and influence the change of such economic elements as the comparative advantage and core competence of a country or region. In order to specify the direction and path of industrial upgrading,the paper,based on the theory of product space and the evolution of comparative advantage,which is proposed by Haussmann,and the development of equip-ment manufacturing industry in Jiangsu Province,constructedsuch indexes as Revealed Comparative Advantage Index,Prod-uct proximity,and Product space density,further studied the influence of product space structure on comparative advantage. The resultsshowed that Product proximity,product space density and other indicators have an effect on comparative advan-tage,i. e. ,the change of product space structure will cause change of comparative advantage,this also provide a new per-spective for determining the direction and path of industrial upgrading. Finally,according to the status of the product space structure of equipment manufacturing industry in Jiangsu Province,this paper put forward the countermeasures and sugges-tions on how to change the product space structure to promote the evolution of comparative advantage and realize the indus-trial upgrading.
