信息化背景下城市群知识溢出——基于长三角、珠三角和京津冀城市群实证研究

Effects of Knowledge Spillovers of Urban Agglomeration Under the Background of Informatization——An Empirical Research on Yangtze River Delta, Beijing-Tianjin-Hebei and Pearl River Delta

结合信息化背景下城市群产业链分工呈现出的新特点,分析城市群产业链分工的主要模式。引入信息化水平、技术距离、对外开放水平等因素构建信息化背景下城市群知识溢出模型,论证产业链中不同地位城市之间知识溢出效应存在的差异,得出非主导产业链的两类城市将会产生分化的结论,并提出加快承接产业转移,促进城市群协调发展的政策建议。

Combining the new feature of urban agglomeration’s industry chain division under the background of informatization,this paper analyzed the main pattern of urban agglomeration’s industry chain division.It also introduced informatization level,technological distance,open level,constructed a model of urban agglomeration knowledge spillovers under the background of informatization.It concluded that cities with different status in the industry chain have differences in the effects of knowledge spillovers;two kinds of cities in Non-dominant industry may divert.At last,this paper gave some policy suggestion that it is better to accelerate the industry transfer,and strengthen the equitable development of urban agglomeration.
