中文摘要：

＂制造业服务化＂已成为全球价值链分工体系的重要特征,并显著影响了企业的国际竞争力。本文采用中国工业企业数据库、中国海关进出口贸易数据库和世界投入产出表的合并数据,实证分析了全球价值链中的制造业服务化对中国企业生产率的影响效应。本文发现：首先,制造业服务化水平有利于提高企业的全要素生产率,尤其是在全球价值链中嵌入程度较高的企业。其次,电信业的服务投入对高价值链嵌入企业全要素生产率的影响最大,金融业次之。最后,服务外包的再配置效应在我们的研究中也被证实,不同类型企业＂制造业服务化＂的生产率效应存在较大的异质性。

英文摘要：

With the increasingly deepening of global value chain, servicification has become a significant global trend, and far-reaching impacts on the international competitiveness. We use Chinese Industrial Enterprises Database, China Customs Trade Database and World Input-Output Database （2000-2006）to consolidate the more refined data, with using input-output analysis to do the empirical analysis of the effect of servicification in global value chain on productivity of Cbina＇s firm. First, when the higher embedded in global value chain, servicification plays more important role in improving firms＇ total factor productivity. Second, the effect of investment in telecommunications services on firms＇ TFP is largest, followed by the financial sector. Finally, the reallocation effect of outsourcing is confirmed in our study.
