【摘要】：市场势力的估计长期困扰着产业组织领域的研究。以中国化学药品制剂企业为例,基于KBL模型对企业市场势力及其影响因素的研究发现:第一,中国化学药品制剂企业的勒纳指数略高于0.3,意味着企业拥有市场势力,这是导致中国药品价格高企的一个重要原因;第二,广告支出强度大、创新能力强的大型制药企业有更高的市场势力。该研究结果为中国医药价格管制政策的制定提供了经验证据:一方面,从动态的角度来看,政府应健全创新支持体系,创造条件推动内资企业、中小型企业、出口型企业通过加强创新而提高竞争力,以长期促进社会福利的改善;另一方面,市场势力的存在推高了当前的药品价格,应重点对大型制药企业与公立医院之间可能存在的合谋行为进行管制。
[Abstract]:The estimation of market forces has long puzzled the research in the field of industrial organization. Taking Chinese chemical preparation enterprises as an example, based on the KBL model, it is found that: first, the Lerner index of Chinese chemical preparation enterprises is slightly higher than 0.3, which means that the enterprises have market power. This is an important reason for the high drug prices in China. Second, large pharmaceutical companies with high advertising spending intensity and strong innovation ability have higher market power. The results provide empirical evidence for the formulation of China's pharmaceutical price control policy. On the one hand, from a dynamic point of view, the government should improve the innovation support system, create conditions to promote domestic enterprises, small and medium-sized enterprises. Export-oriented enterprises enhance their competitiveness by strengthening innovation in order to promote the improvement of social welfare in the long run; on the other hand, the presence of market forces has pushed up current drug prices. Emphasis should be placed on possible collusion between large pharmaceutical companies and public hospitals.
