占据基础软件市场支配地位的企业既提供基础软件又提供应用软件时,往往有动机拒绝提供基础软件的兼容信息。如果拒绝提供的兼容信息为应用软件市场竞争对手开展竞争所必不可少,具有排除相邻市场竞争之危险,并且无正当理由,就应当认定为滥用市场支配地位。我国反垄断执法机构应当借鉴欧盟经验,高度关注软件兼容信息的披露问题。 Businesses that dominate the underlying software market often have the incentive to refuse to provide compatible information on underlying software when they provide both basic and application software. If the refusal to provide compatible information is essential for competitors in the application software market, with the risk of excluding competition from neighboring markets, and without justifiable reasons, should be identified as abuse of market dominance. Anti-monopoly law enforcement agencies in our country should learn from the EU experience and pay close attention to the disclosure of software compatible information.
