摘要/Abstract

摘要：

以双边市场理论为基础，在考虑用户多归属行为的情况下，研究了互联网平台型企业的横向合并以及合并后禁止多归属对社会总福利的影响。多归属用户的存在，对社会总福利的提升是有利的。多归属用户越多，也越有利于企业横向合并后社会总福利的提升。如果合并后平台型企业禁止了用户的多归属行为，将有很大的可能性降低社会总福利。反垄断监管机构可以对平台型企业的横向合并行为本身比较宽容，但应该更加关注多归属用户的比例，以及企业禁止用户多归属的行为。

Abstract:

Based on two-sided market theory and in the case of considering users' behavior of multi-homing, the impact of Internet platform enterprises' horizontal merger and the prohibition against multi-homing after the merger on total social welfare are studied. The existence of multi-homing users helps improve total social welfare. If there are more multi-homing users, total social welfare will be better improved after enterprises' horizontal merger. If platform enterprises prohibit users' behavior of multi-homing after the merger, total social welfare is very likely to decrease. The antitrust regulator is advised to keep tolerant to platform enterprises' behavior of horizontal merger. However, but pay more attention to the proportion of multi-homing users and enterprises' behavior of prohibiting users' multi-homing.

Key words: platform enterprises, multi-homing, horizontal merger, total social welfare, antitrust regulation
