摘要
构建了一个包括资本、劳动力和土地空间资源三个投入要素的城市经济增长模型,认为城市经济增长的规模经济来自于未补偿的知识溢出效应,并假设这种溢出效应以外部性作用于资本要素,构建计量分析模型,引入区位因素虚拟变量,针对沿海—内地两大地带之间和内部分成三种观察组,分析了城市经济在包含区位因素下的增长机制。结论为:2004～2005年间中国城市经济处于规模报酬不变的增长阶段;城市经济地带性差异显著;水陆口岸对于沿海城市经济的发展具有显著的影响;航空口岸具有负效应。
This paper constructs an urban economic growth model including three factor inputs： capital, labor and land space resources. The economies of scale of urban economic growth come from uncompensated knowledge spillover effect, it assumed that this spillover effect influence capital on externality and build econometric analysis model, and introduce the dummy variable of location factors, it divided coastal areas and the mainland into three observation groups and analyzed the urban economic growth mechanism contained the location factor, it had several conclusions： Chinese urban economy is in the growth stage of constant returns to scale; urban economy has zonal statistical significance ; land and sea ports have a sig- nificant impact on the economic development of coastal cities; air ports have a negative effect. Conclusions of it need to be further deepened and improved.
