中国制药业R&D的规模经济

The Economy of Scale of R&D in the Chinese Pharmaceutical Industry

通过统计资料分析，本文发现中国制药业新产品Ｒ＆Ｄ具有显著的规模经济，即，随着企业规模增大，平均而言，每个新产品开发项目的投入更多、产出更大、而且生产率更高，因而充分利用规模经济应成为新药开发的重要组织方式；但目前Ｒ＆Ｄ资源的产业集中程度较低，大企业在Ｒ＆Ｄ项目数量、专业人员及开发资金的比重上都低于中型企业，迫切需要通过集中化与规模化途径，尽快将Ｒ＆Ｄ资源集中到大企业，以提高制药业Ｒ＆Ｄ的效率。

By statistical data analysis, it found that R&D of new products in the Chinese pharmaceutical industry has the signfi-cant economy of scale, that is, on average, the bl bigger the scale of a firm is, the more the input, output and productivity of a new product developing project will be, thus the full usage of economy of scale should be a important mode to organize new drugs developments. However, the concentration degree of R&D resources in the industry was low, and the big firme had less shares than median ones on the number of R&D projects, research workers and capitales, therefore, it's necessary to concentrate R&D resources to big firms as quickly as possible, by concentration and expansion, to enhance the efficiencies of R&D in the pharmaceutical industry.
