Study of the effects of nuisance zoning on land and labor markets

土地利用政策对城市化进程的影响分析：在一个NEG模型框架内，试图说明城市化率是各社会经济主体理性行为的综合结果。特别是，一个模型的构建铭记在心，以解释在中国的城市化进程，政府在管理土地利用的作用是明确纳入和政策效果可以评估。主要结论如下。1.影响城市化率的政策变量是城乡居民地面积比和城乡居民地公共存量比，城市化率随着城乡居民地面积比和城乡居民地公共存量比的增加而降低。在运输成本效应方面，制造业产品运输成本的降低会降低城市化率。另一方面，农产品运输成本的降低将促进城市化进程。2.低技能劳动力的增加将增加产出，从而提高效用水平。另一方面，人口增加将减少人均住宅面积，从而降低公用事业水平。这意味着存在最佳人口规模。扩展的哈里斯-托达罗模型的分析：开发了农村-城市移民的基本哈里斯-托达罗模型的扩展模型，我们分析了基础设施可用性的影响以及经过时间考验的收入影响，同时通过提供和融资基础设施来适应政府行为。我们的理论分析证实，基础设施的存在可能是做出迁移决策的重要因素。通过与基本Harris-Todaro模型的比较，发现基本模型中不存在托达罗悖论，而扩展模型中存在托达罗悖论。

The analysis of land use policy effects on urbanization process : within a framework an NEG model it was intended to show that urbanization rate is determined as a synthetic result of rational behavior of each socio-economic agent. In particular, a model is constructed with bearing in mind to explain the urbanization process in China such that the role of government in managing land use is explicitly incorporated and policy effects can be evaluated. Major conclusions are as follows. 1.The policy variables affecting urbanization rate are the ratio of residential land area between rural and urban districts and the ratio of public stock for living between the two district the urbanization decreases with both of them. Concerning transport cost effect, a decrease in the transport cost of manufacturing good will lower the urbanization rate. On the other hand, lower transport cost of agricultural product will promote urbanization. 2.An increase in low-skill labor will increase output and thus increases utility level. On the other hand, increased population will reduce per capita residential lot size and thereby lower the utility level. This implies that an optimal population size exists.The analysis of an extended Harris-Todaro model : Developing an extended model of the basic Harris-Todaro model of rural -urban migration, we analyzed the effects of infrastructure availability together with time -tested income effects while accommodating government behavior through the provision and financing infrastructure. Our theoretical analysis confirms that infrastructure presence can be a significant factor in making migration decisions. Comparison with the basic Harris-Todaro model also revels that the Todaro paradox is absent in the basic model, it can be present in the extended model.
