中文摘要：

文章利用1995-2010年中国高技术产业细分行业的面板数据,在考虑新产品需求、市场化进程等因素的情况下,实证分析了垂直专业化对研发投入的影响及其行业差异。研究结果显示,垂直专业化对我国高技术产业的研发资本投入和研发人力投入均具有正向促进作用,而且入世后这种促进作用更大;垂直专业化对研发投入的影响存在行业差异性,在垄断程度较低、技术密集度较高和外向度较高的行业中,垂直专业化对研发投入的促进作用更加显著。

英文摘要：

Based on the sub-industrial panel data of China＇s high-tech industry from 1995 to 2010,this paper makes an empirical study of the effect of vertical specialization on RD input and its industrial differences by taking into account the demand for new products,marketization process,and so on.The results show that vertical specialization has a positive impact on RD input of capital and labor in high-tech industry,and the positive impact is more significant after China＇s entry into WTO;the effect of vertical specialization on RD input varies with the industries,which is more significant in industries with lower degree of monopoly,higher technology-intensive degree and higher ratio of dependence on foreign trade.
