中文摘要：

将异质性跨国外包分为实物外包和服务外包，对外包率进行了再测算，在异质性跨国外包对制造业生产率影响机制的理论分析模型中引入价值链分工体系，并基于要素密集度分类的制造行业面板数据分析了制造业生产率效应差异。研究结果表明：服务外包对制造行业总体生产率有促进效应，但实物外包的生产率效应不明显；异质性跨国外包对不同要素密集度制造业生产率的影响程度不同，服务外包对资本、技术密集型制造业生产率的影响大于对劳动、资源密集型制造业生产率的影响；但实物外包对劳动、资源密集型制造业及资本、技术密集型制造业生产率的影响并不显著；产业环境的改善对制造业生产率具有显著提升作用。

英文摘要：

This paper divides the heterogeneous cross-border outsourcing into material outsourcing and service outsourcing and conducts a recalculation on the outsourcing rates. Then it introduces the value-chain division system into the theoretical analysis model of the influencing mechanism of het- erogeneous cross-border outsourcing on the productivity of manufacturing industry, so as to analyze the effect differences of the manufacturing industry productivity based on the panel data of the manu- facturing industry classified according to factor intensity. The results of the study indicate that the ser- vice outsourcing has a significant positive effect on the overall productivity of the manufacturing in- dustry, while the productivity effect of material outsourcing is not obvious. The heterogeneous cross-border outsourcing has different effects on the productivity of manufacturing industry with differ- ent factor intensity; the impact of service outsourcing on the productivity of capital or technology-in- tensive manufacturing industries is greater than that of labor or resource-intensive manufacturing indus- tries. However, the impact of material outsourcing on the productivity of labor or resource-intensive manufacturing industries and capital or technology-intensive manufacturing industries is not significant. The improvement of the industrial environment can play a significant role in promoting the productiv- ity of the manufacturing industry.
