中文摘要：

以2013年我国正式在上海自由贸易试验区试行负面清单管理模式为背景，文章从贸易附加值的视角就实施负面清单对一国服务业国际竞争力产生的影响进行实证研究，为未来外资准入体制的改革提供参考依据。研究发现，相对于未实施负面清单的国家，实施负面清单管理模式的国家，其服务业的国际竞争力水平下降，表明负面清单实施后，进入东道国的外资企业可凭借其竞争优势挤占该国服务业出口中的国内附加值份额，弱化东道国国内企业在本国出口中的竞争优势。进一步的差异化分析还发现，东道国的GDP总量越低、法制环境越差、缔约国的GDP总量越高，负面清单管理模式对东道国服务业国际竞争力产生的负面影响越大，并且传统服务业的竞争力受到负面清单的冲击更大。因此，文章认为在未来负面清单管理模式的改革中，我们应坚持对外开放与对内改革并举，通过规范和完善法制环境来消除对外开放带来的负面影响；同时，我们要根据行业与地区间的差异安排对外开放的程度和顺序，以确保在深化服务业国际分工的同时有效提升我国服务业的国际竞争力。

英文摘要：

In 2013, China formally tried out the negative list management mode in Shanghai Free Trade Zone. Based on this background, this paper makes an empirical study of the effect of the implementation of the negative list management mode on the international competitiveness of service industries in a country from a perspective of value added in trade, to provide references for future reform of foreign investment access system. It shows that compared with the countries without the negative list approach, the international competitiveness of service industries in countries with the negative list approach reduces, indicating that after the implementation of the negative list approach, foreign enterprises entering a host country can crowd out domestic value-added share of the host country＇ s services exports by their competitive advantages, and weaken the competitive advantage of domestic enterprises in the host country in domestic exports. Moreover, the differentiated analysis results show that the negative impact of negative list on the international competitiveness of service industries is likely to be more significant for the host countries with lower GDP, worse law environment and for countries applying a negative list for partners with higher GDP, and the international competitiveness traditional services suffer more from the negative list. As a result, this paper concludes that it is necessary for China to reform the internal legal system during the international investment liberalization process, which means we should improve the legislation about foreign investment in service industry to make up for the negative impact of the negative list approach. And China should take the difference in both sectors and regions into consideration to optimize the degree and order of opening-up, and make sure that China could promote the service competitiveness effectively during the international investment liberalization process.
