Study on the R&D Contribution Rate of Listed Pharmaceutical Enterprises in Southwest China Based on Super-efficiency DEA Model / 中国药房

ABSTRACT

OBJECTIVE： To provide reference for pharmaceutical enterprises to enhance the R&D capability and improve the R&D investment strategy. METHODS： The annual report data of 13 listed pharmaceutical enterprises in southwest China were collcted. Taking fixed assets， operating costs， the number of employees in service and the amount of R&D investment as input indicators， net profit， operating income and earnings per share as output indicators， the efficiency values were calculated by using MyDEA 1.0 software based on super-efficiency DEA model. The operating efficiency of enterprises with or without R&D input were compared； the contribution rate of R&D investment to enterprises were calculated. Finally， Wilcoxon symbolic rank test was carried out by using SPSS 20.0 software to compare the difference. RESULTS： From 2013 to 2015， 10 of the 13 listed pharmaceutical enterprises had increased their R&D investment， which indicated that listed pharmaceutical enterprises in southwest China paid more attention to R&D investment. For three consecutive years， the efficiency value of R&D investment of the 13 listed pharmaceutical enterprises was significantly higher than that of the enterprises without R&D investment， and the number of the former reaching DEA efficiency was more， indicating that R&D investment was positively correlated with the operational efficiency of pharmaceutical enterprises. The Wilcoxon symbol rank test also confirmed that R&D investment was an effect input. After three enterprises joined the R&D input index， their operational efficiency was improved， and their R&D contribution was greater. Five enterprises had zero R&D contribution， their efficiency value remained unchanged whether or not they joined R&D input. The R&D contribution of other listed pharmaceutical enterprises varied greatly in each year. CONCLUSIONS： At the overall level of the industry， enterprises should increase their R&D investment and pay attention to improving R&D efficiency， establish a sound R&D innovation system and R&D personnel training mechanism， establish an integrated training mode of production， learning and research； the government should create an environment to support R&D activities of pharmaceutical enterprises. For individual enterprises， different strategies should be adopted based on practical situation in order to improve the pulling effect of R&D input on the operational efficiency of enterprises.
