制度、基础设施与经济增长

本文建立包含制度因素的生产函数,通过动态规划和比较静态分析,讨论了制度、人均基础设施与经济增长的关系.通过研究发现,制度质量不同,资本的边际产品随人均资本积累变化的趋势不同.而且制度会通过影响人均资本产出弹性而影响基础设施对经济增长的贡献.从而导致经济增长率的不同.而且本文证明了最优税率随制度质量提高而变高.最后,经济增长的稳定状态也取决于制度质量,制度质量越高,均衡状态时的人均消费越大,所需人均资本投入越小.

Institution,Infrastructure and Economic Growth

This paper build up a production function which including institution factor. By using dynamic program and compared static analysis method, we investigate how institution affect the relationship between infrastructure and economic gro-mh. As is found in this paper, that how much infrastructure can contribute to economic growth depends on what level the institution is. And both marginal product of capital and optimal tax rate are affect by institution. Moreover, if the institution is better, in the equilibrium state, per consumption will be larger with less per capital input.
