摘要
本文首先构建理论模型阐述了上游垄断影响企业产品质量选择的作用渠道,并澄清了其阻碍产品质量升级的条件。在此基础上,克服了以"价格法"衡量产品质量的局限性,结合《中国海关贸易数据库》和《中国工业企业数据库》,采用"回归反推方法"对中国企业的产品质量进行了测算。研究发现,上游垄断对产品质量升级的作用取决于垄断的成因以及下游的竞争程度:由政府保护所形成的垄断明显不利于产品质量升级;由企业自身的高效率所导致的垄断对下游产品质量升级的作用与下游竞争程度有关,下游竞争程度越高,则其正面作用越小。随着下游行业竞争的放开,其负面作用正在逐步凸显。
This paper builds a model to investigate the impact of upstream monopoly on downward firm＇s quality choice, giving the condition under which upstream monopoly blocks quality upgrading. We then empirically examine the impact of upstream monopoly on firms＇ quality upgrading. Instead of using the unit value method of measuring product quality, this paper combines the Chinese industrial firm data and Chinese custom data, and uses the regression method to compute the firms＇ product quality. The results show that： First, higher upstream monopoly is on average associated with higher product quality. Second, the impact of upstream monopoly is heterogeneous across firms and industries, government subsidized monopoly has a negative effect on downstream product quality, and the negative effect is more pronounced for industries with larger extent of downstream competition.
