产品空间视角下制造业结构转变研究——以江浙沪为例

本文在产品空间视角下，将产品空间结构理论从国际贸易领域移植到国内区域层面，利用中国30个省份2003～2011年145类制造业3位码细分行业数据和2012～2014年147类制造业3位码细分行业数据，构造中国制造业产品空间，采用固定效应模型和Probit模型检验产品密度对比较优势的影响，并以江浙沪为例，对制造业结构转换目标选择进行了探讨。研究发现：在国内区域层面，产品密度在产业转型中发挥着引领产业创新和阻止产业衰退的双重作用。在产业结构转换中，需要遵循此规律，选择合适的转换目标，避免结构转换中的断档停滞。

Analysis of Manufacturing Structural Transformation from the Perspective of Product Space——Examples of Shanghai,Jiangsu and Zhejiang Province

Thispaper applies the theory of product space into the regional level to further study the manufacturing structural transformation.It constructs the manufacturing product space of China using 3 digital manufacturing industry data in 2003-2014 period and establishes fixed effects model and Probit model to test the impact of product density on its comparative advantage.This paper also analyzes how to choose the goal of structural transformation taking Shanghai,Jiangsu and Zhejiangas examples.It is found that the density of product has a significant positive influence on its comparative advantage.The density of product plays role both inleading industrial innovation and preventing industrial decline.It is essentialto choose the products according to their density to cultivate the comparative advantage to avoid failures in structural transformation effectively.
