摘要

全球每天有数十亿用户使用数字零价格服务。本研究以即时通讯服务为例,提出一种数字零价格服务的市场定义方法。我们采用成本小但显著非暂时性增加测试,这是价格小但显著非暂时性增加测试的改进版本,并在考虑数字服务特征网络效应的情况下进行联合分析。结果表明,仅考虑价格效应时,需求的价格弹性为0.628,临界加成比为1.492-1.542。考虑直接网络效应时,需求的价格弹性为1.728,临界加成比为0.479-0.529。当考虑具有间接网络效应的双边市场时,需求的价格弹性为2.162,临界加成率为0.363-0.413。因此,当考虑网络效应和双边市场时,免费信使服务需求的价格弹性更高。

DELINEATING ZERO-PRICE MARKETS WITH NETWORK EFFECTS: AN ANALYSIS OF FREE MESSENGER SERVICES
Billions of users worldwide utilize digital zero-price services every day. This study proposes a market definition method for digital zero-price services, using the messenger service as an example. We employ the small but significant nontransitory increase in cost test, which is an improved version of the small but significant nontransitory increase in price test, and conduct conjoint analysis while considering the network effect, a characteristic of digital services. Our results show that the price elasticity of demand is 0.628 and the critical markup ratio is 1.492–1.542 when only the price effect is considered. When the direct network effect is considered, the price elasticity of demand is 1.728 and the critical markup ratio is 0.479–0.529. Furthermore, when considering a two-sided market with indirect network effects, the price elasticity of demand is 2.162 and the critical markup ratio is 0.363–0.413. Thus, the price elasticity of demand for free messenger services is higher when the network effects and two-sided markets are considered.
