摘要
经济集聚的外部性导致知识溢出,知识溢出会使技术创新对区域产业结构升级产生空间效应。通过基于结构偏离度的Hamming贴近度、夹角余弦法、PCA等测度了产业结构"两化"水平和技术创新强度,构建了基于经济集聚度的空间权重矩阵,并利用1997—2014年间30个省市(西藏除外)的面板数据进行SDM实证检验,结果表明:技术创新强度对我国"两化"发展具有显著为正的空间效应;经济集聚是促进创新对高级化空间效应的必要条件,它能将创新对合理化的空间效应放大近4倍;就合理化维度而言,东部地区创新的边际收益高,中部地区集聚的边际收益高,西部地区依赖政府调控,技术创新强度对西部地区产业结构合理化的空间效应不显著。
The externality of economic agglomeration leads to knowledge spillover, which will make technological innovation have spatial effect on regional industrial upgrading. Using the Hamming closeness method based on the structural deviation degree, the angle cosine method and PCA, we measure the rationalization and supererogation level of industrial structure, and the intensity of technology innovation. Then we construct the spatial weight matrix based on economic agglomeration degree, and employs the SDM method to empirically test the effects of the technology innovation intensity on the rationalization and supererogation level of industrial structure, using the panel data of 30 provinces （except Tibet） in China during 1997-- 2014. The results show that the intensity of technological innovation has a significant positive effect on the rationalization and supererogation level in China. Economic agglomeration is a necessary condition to promote the spatial effect of innovation on supererogation, and can amplify the spatial effect of innovation on rationalization level of industrial structure nearly 4 times. In terms of rationalization dimension, innovation has the highest marginal revenue for eastern regions, economic agglomeration for middle regions. However, west regions depend on government regulation, and its technological innovation intensity has no significant spatial effect on the rationalization of industrial structure.
