在联立框架中的产业集聚与知识溢出

传统的有关产业集聚和知识溢出的研究采用的单向方程模型往往会产生内生性偏差,本文尝试建立联立方程模型来研究产业集聚与知识溢出.实证结果表明,联立方程模型的建立纠正了内生性偏差,产业集聚和知识溢出并非单向的关系,它们彼此加强;同时,提高了知识溢出对产业集聚作用量化的准确性,使结果更加符合理论预期;由于定域化经济和城市化经济存在,知识溢出、劳动力汇集、人口和投入变量与产业集聚正相关.

Industrial Cluster and Knowledge Spillover in Simultaneous Framework

Traditional studies on industrial cluster and knowledge spillover use the equation of single model,which will often produce endogenous deviation.This paper attempts to establish the model of simultaneous equations to study industrial cluster and knowledge spillovers.Empirical results show that the simultaneous model corrected endogenous deviation and that the relationship between industrial cluster and knowledge spillovers is inter-connected instead of a one-way pattern.Meanwhile,our model enhances the accu...
