我国医药制造业大型企业研发投入内部影响因素的实证研究

Empirical Study on the Relationship between Internal Factors and R&D Investment of Large-scale Enterprises of Pharmaceutical Manufacturing

目的通过明晰我国医药制造业大型企业研发投入受哪些内部因素的影响及影响关系,为提升医药行业研发投入水平提供参考。方法基于1995-2014年医药制造业大型企业经济和研发情况的调查数据,使用因子回归分析方法,实证分析研发人力、企业规模、盈利能力、研发知识产出等内部因素对医药制造业研发投入的影响。结果研发人力、企业规模、盈利能力、研发知识产出均与医药制造业研发绝对支出呈显著正相关关系,但对研发投入强度影响甚微。结论增加研发人力、扩大企业规模、提升盈利能力、促进研发知识产出可明显提高医药制造业研发投入水平。为此政府和企业可针对不同的影响环节采取相应的激励手段,进而带动科研创新的投入。

OBJECTIVE To provide a reference for enhancing the level of research and development investment of the large-scale enterprises of pharmaceutical industry by identifying what kind of internal factors influence the the research and development investment and how they do with it. METHODS The thesis empirically analyzed the relationship between research and development personnel,firm sizes,profitability,research and development knowledge outputs and the research and development investment of pharmaceutical manufacturing,based on 1995- 2014 survey data of research and development conditions and economic conditions of large enterprises of pharmaceutical manufacturing and with the use of factor regression analysis method. RESULTS R D personnel,firm size,profitability,research and development knowledge outputs are positively correlated with R D expenditure of pharmaceutical manufacturing,but they have little effect on research and development intensity. CONCLUSION Increasing research and development personnel,expanding firm sizes,enhancing profitability,and promoting research and development knowledge outputs can significantly improve the R D investment of pharmaceutical manufacturing. Government and businesses can take the appropriate incentives for different aspects,stimulating the investment in research and innovation.
