贸易自由化、经济增长与减轻贫困——基于中国省际数据的经验研究
摘 要： 贸易自由化是减轻还是增加了贫困？这是个有争议的问题。本文试图从经济增长的角度出发构造了一个联立方程组模型，利用中国的省际数据来分析贸易自由化对贫困的影响。研究结果显示：全国数据的回归结果表明贸易自由化通过促进经济增长提高了贫困人口的收入；东部和中西部数据回归结果以及反事实估计结果均显示贸易自由化有效减轻了东部地区的贫困，但是对西部地区的贫困减轻作用不显著；通过引入交互项，本文进一步发现贸易自由化通过经济增长对贫困的影响随贸易自由化程度加深而提高。

Trade Liberalization, Economic Growth and Poverty Reduction
Abstract: Whether the trade liberalization is reduce or increase poverty? This is an controversial issue in academia. This paper tries to construct a simultaneous equations model and use the interprovincial data in China to analyze the relationship between trade liberalization and poverty. We find that trade liberalization is helpful to increase the income of poverty when we use the whole data. However , when we use the coastal data and inland data separately , we find trade liberalization is good for poor people in coastal area and has not obvious effects on poverty reduction in inland area. And the anti-fact estimations also support those results. In the further research we find that the influence of trade liberalization on poverty recuction will become remarkable when the degree of trade liberalization moves forward .
