我国医药制造业研发投入影响因素的实证分析

An empirical analysis of factors influencing R&D investment in China's pharmaceutical industry

目的了解我国医药制造业研发投入受哪些因素影响和影响机制,为提升医药行业研发投入水平提供参考。方法基于1995—2013年医药制造业经济和研发情况的调查数据,使用因子分析回归方法,实证分析企业规模、盈利能力、研发人力资本、行业中企业竞争程度、新产品市场需求和政府直接资助等因素对医药制造业研发投入的影响。结果政府直接资助(0.351)、行业中企业竞争程度(0.288)、企业规模(0.257)、研发人力资本(0.198)均与医药制造业的研发投入显著正相关,影响程度依次减弱;但行业盈利水平(-0.129)与研发投入负相关;新产品市场需求(-0.029)对研发投入无影响。结论扩大企业规模、增加研发人力、合理引导企业参与竞争、增强政府直接扶持力度等因素可明显提高医药制造业研发投入水平。

Objective To provide a reference for enhancing the R＆D investment in China＇s pharmaceutical industry by analyzing the factors that influence the R＆D investment. Methods Based on the data of R＆D investment and economic conditions of pharmaceutical industry from 1995 to 2013, factor analysis and regression analysis are used to study the factors such as the scale of enterprise, profitability, personnel for R＆D, competition degree, marketing demand for new products and direct government subsidy that influence R＆D investment. Results Direct government subsidy（0. 351 ） ,the competition degree（0. 288 ） ,the scale of enterprise （0. 257）, personnel for R＆D （0. 198） are positively correlated with R＆D expenditure in pharmaceutical industry, but the profitability of the enterprise （ -0. 129 ）is negatively correlated with R＆D expenditure. And the marketing demand for new products （ - 0. 029 ） has not effect on R＆D investment. Condusions Expanding the scale of enterprise, increasing R＆D personnel, guiding enterprises to participate in competition reasonably and enhancing government＇s direct support can improve the R＆D investment in pharmaceutical industry significantly.
