基于空间一般均衡理论的土地要素对经济影响机制研究

Study on Mechanism of Land Factors Influencing Economy Based on Spatial General Equilibrium Theory

文章纳入土地要素的单部门新经济地理模型,舍弃了自由企业家模型中的均质商品部门,现代部门的投入均由土地与劳动力复合形成,不可移动的土地要素的价格由区域经济演化过程内生决定,进而影响要素收入分配。通过在空间一般均衡的领域内作线性化处理,得出解析解,以此系统揭示土地要素对空间经济的三种分散作用机制,即收入挤出效应、价格效应和逆多样化效应。上述效应随着土地要素在生产中的密集程度下降而减弱。

This paper adopts the single-sector new economic geography model, which abandons the homogeneous commodity sector in the free entrepreneur model. Modern sector inputs are formed with the combination of land and labor force. The price of immovable land elements is determined endogenously by the evolution of regional economy, and then affects the income distribution of factor. By means of linearization in the domain of spatial general equilibrium, the analytical solution is obtained to reveal the three decentralized mechanisms of land elements on spatial economy, namely, income crowding out effect, price effect and inverse diversification effect. The above-mentioned effects weaken with the decrease of the density of land elements in production.
