后发国家分工演进中的政府作用——新兴古典框架下的一种临界状态分析

The Role of Government during the Evolution of Division of Labor in the Post-developing Countries——An Analysis of a Critical State in the Framework of New Classical Economics

利用新兴古典经济学中的超边际分析方法,通过引入外生政府来分析后发国家处于"自给自足"与分工之间的临界状态时,政府在促进分工演进中的作用。研究表明,在此临界状态下,个人没有动力促进分工演进,政府为了获取更多的税收,有动力通过提高交易效率以促进分工演进。并且,在不同的初始条件下,政府在促进分工演进过程中的政策变化会产生不同的福利影响。

The authors analyze the role of the exogenous government of post-developing countries in a critical state which is between autarky and division of labor by using the method of inframarginal analysis.The study shows that the individuals have no incentive to promote the division of labor in the critical state,but the government has the incentive to do it in order to gather more taxes through improving the transaction efficiency.The policy of the government changes will have different welfare effects under different initial conditions during the promotion of the division of labor.
