使用中国工业企业数据库的微观数据,运用OP法估计了医药制造业的全要素生产率,并对其与研发投资的关系进行了实证研究.我国医药制造业全要素生产率与研发投资强度大致上呈现正向关系.在加入研发投资的二次项之后,医药制造业全要素生产率与研发投资强度呈现倒U型的关系.应鼓励医药制造业企业适当地提高研发投资强度,同时鼓励企业将规模做大,并控制资产负债率,以此来推动我国医药制造业走上内涵式增长的健康发展道路.%Using the micro-level data of Chinese Industrial Enterprise Database,pharmaceutical manufacturing industry's total factor productivity is estimated with OP method.Based on the empirical study of the relationship between TFP and R&D investment,there generally exists a positive relationship between them.If the quadratic term of R&D investment intensity is added to the regression,there exists an inverted U curve relationship between TFP and R&D investment intensity.The pharmaceutical manufacturing enterprises should be encouraged to appropriately increase R&D investment intensity.At the same time,the enterprises areencouraged to expand the scale and control the assets liabilities ratio.These measures will be helpful to lead China's pharmaceutical manufacturing industry to go on an intensive growth path and promote healthy development of the industry.
