东道国税收激励政策的福利效应分析

应用税收激励来吸引外商直接投资是目前世界上大多数国家常用的政策手段。然而,税收激励政策在促进东道国经济增长的同时对东道国福利的影响是不确定的,需要对税收激励政策的成本和收益进行综合评估。本文对经典的Macdougall一般福利效应模型做进一步拓展,引入税收激励来分析外商直接投资对福利效应的影响,结果表明:税收激励政策能否增进一国福利水平主要取决于外资企业的技术外溢。从这个结论出发,本文对我国当前税收优惠政策的福利效应进行评述,进而对我国外商投资税收优惠提出政策建议。

Most countries on the world often resort to tax incentives to attract FDI. It is generally agreed that tax incentive policy can help develop the economy of host countries, but its welfare effects is not so sure, so a comprehensive cost-benefit analysis of the tax incentive policy is needed. This article extends the classic FDI model of Macdougall and introduces the tax incentive to analyze the welfare effects. Results indicate that: whether the tax incentive policies could improve the welfare for the host country mostly depends on the technological spillover of foreign investments. Based on this conclusion, we review the welfare effects arising from the currently conducted tax preference policies in China, and some suggestions are put forward at the end of the paper.
