制度、增长与收敛——一个基于索洛模型的分析框架

Institutions,Economic Growth and Economic Convergence——A Framework Based on the Slow-Swan Model

标准的经济增长理论把制度看作是既定不变的并且不存在交易费用的,所以无法认识到制度对经济增长的重要性。将制度作为一个变量引入索洛模型,可以构造一个包含制度的、技术内生的增长模型。通过模型的推导可以得出这样的结论:制度质量越好,人均产出增长率越高;人均产出存在关于制度的条件收敛。并进一步得出这样的推论:欠发达国家想获得“后发优势”赶超发达国家,前提条件是具备良好的制度或能够持续改善其制度。

Standard economic growth theory assumes that institutions are a bundle of given policies, and no trade-off cost are incolved,and thus they are not important for economic growth. This article introduces a variable of institutions into Slow - Swan model and assumes physical investment and technological progress are the function of institutions. We find from the model that the higher quality of institutions, the higher growth rate of output per capita an economy has. We also find the conditional convergence among the countries with the institutions.
