Does Internet Third-party Payment Platform Become Monopoly: Based on the Measurement of Market Power
-
摘要: 企业市场势力是甄别垄断的重要指标，平台经济反垄断需要充分考虑厂商的市场势力。选取第三方支付作为研究对象，采用修正后的勒纳指数测算第三方支付平台厂商的市场势力，结果表明：支付宝、财付通等9家平台厂商均利用市场势力来提升其垄断能力，以期获得垄断地位，且主要是利用显性市场势力来提升其垄断能力。但市场份额与市场势力之间存在着背离，市场份额最高的两家厂商为支付宝和财付通，其市场势力却处于底端水平。因此，加强第三方支付等互联网平台经济的反垄断，需要同时考量平台厂商的市场份额与市场势力，将其作为反垄断的重要评判标准。Abstract: The market power of a company is an important indicator to identify monopoly. Anti-monopoly in platform economyis needed to fully consider the market power of platforms. This study selects third-party payment as the research object, and uses the revised Lerner Index to measure the market power of third-party payment market platforms. The results show that 9 platforms including Alipay and Tenpay all use the market power to enhance monopoly capability and obtain the monopoly position, which the dominant market power is mainly used to enhance the monopoly ability.However, there is a divergence between market share and market power. The two platforms with the highest market share are Alipay and Tenpay. The market power of these two platforms is at the bottom. Accordingly, market share and market power of platforms should be used as an important criterion for anti-monopoly of the internet platform economy such as third-party payment.
