长三角地区制造业升级路径研究—基于产品空间理论

Study of manufacturing industrial upgrading path in Yangtze RiverDelta: Based on product space

基于产品空间理论,利用2009—2018年长三角地区制造业数据分析地区产品空间,实证检验产品密度与比较优势关系,研究地区升级路径。研究发现:长三角地区制造业转型升级过程中存在路径依赖,地区倾向于生产与当前优势产品关联性较高的新产品;产品密度对促进新产业升级和阻碍优势产业失势有双重作用,地区劳动密集型产业存在退出障碍,阻碍资本和技术密集型产业发展,不利于地区产业结构优化升级。对此,应当结合地区制造业发展现状,发挥路径依赖的正面作用,推动产业多样化发展,优化产业退出机制,促进地区制造业转型升级。

Based on the product space theory,this paper analyses Yangtze River Delta regional product space by using the manufacturing production data from 2009 to 2018 and empirically tests the relationship between product density and comparative advantage.Then we research on regional upgrade paths.The results show that:there is path dependence in the transformation and upgrading of the manufacturing industry.The region tends to product new products that are highly related to the current advantageous products.Product density plays a dual role in promoting the upgrading of emerging industries and hindering the decline of competitive industries.There are barriers to the withdrawal of labor-intensive industries in a region,hindering the development of capital-intensive and technology-intensive industries,and hindering the innovation and upgrading of regional industries.Thus,it is necessary to combine the development status of regional manufacturing industry,then giving play to the positive role of path dependence to promote industrial diversification development and optimizing industrial withdrawal mechanism to achieve the upgrading of regional manufacturing industry.
