Research Of The Influence Of Knowledge Intensive Business Service On Innovation Performance

Facing the increasing stock of knowledge and the diminishing technological opportunities, it is becoming more and more difficult to innovate. As intermediate product provider, KIBS (knowledge intensive business service) can help innovator to raise work efficiency and improve the quality of research output. KIBS is regarded as the second infrastructure of the knowledge-based economy and the other engine for modern economic growth with manufacturing industry. Since the middle age of 1990s, foreign scholars began to pay attention to KIBS and carried out series of research on KIBS innovation、the relationship between KIBS and manufacturing innovation. While in domestic the research of KIBS is at the start-up phase, most of which is on influence mechanism、pattern and process and some other qualitative research. This paper makes summary of the current research achievements at home and abroad and gives a brief introduction of KIBS about its main concept、development history and the relationship with innovation. In the empirical part, this paper focuses on database application which is one branch of KIBS. We investigate the influence of six widely used databases(China Health and Retirement Longitudinal Study、China Health and Nutrition Survey、China Household Income Projects、China Family Panel Studies、Chinese Longitudinal Healthy Longevity Survey、Chinese General Social Survey) nowadays in Chinese academics on the quality of publications. Based on the Difference-in-Difference method, it is found that after the utilization of database, the quality of publications improved apparently, especially with CHARLS, CHIP and CLHLS. Besides, the Placebo Test also supports the finding. The paper proposes suggestions from two perspectives:the government’s role in supporting the development of KIBS; Two basic question for the publication of micro-database in the future, namely who issue databases and who should get databases.
