With the development of data-driven information and communication technologies, global IT companies have expanded their scope to the platform industry, and major foreign countries have developed national development strategies with the aim of revitalizing the digital economy. In particular, the Covid-19 outbreak in 2020 has activated non-face-to-face transactions, which has exploded the demand for platform companies that can run search, order, and payment online. Typical applications include search engines, social networks, Internet shopping, and delivery intermediary applications. Instead of providing free services to users, these online platform companies are securing user data and using it to grow their businesses. For example, personalized advertisements can be provided by analyzing data such as search contesnts, consumption patterns, eating habits, conversation contents, etc. formed by using the personal information of the users and the service itself can be improved. Within the online platform market, the business will operate based on this, allowing companies that utilize a larger amount of data to gain the upper hand. As a result, there is a problem of unfair practices caused by the data monopoly of digital giant companies. Major foreign countries such as the U.S., Germany, EU, and Japan recognized such a big data monopoly as a competitive legal issue, accumulated judicial precedents, and established regulatory systems. The United States discussed data as a major issue in reviewing mergers between platform companies, and EU also sought to address data imbalances by specifying the obligation of large platform companies to provide data. In Germany, the revision of the Competition Restriction Prevention Act reflected data-related issues in the digital market in regulations, and Japan also preemptively prevents platform companies from monopolizing data by establishing guidelines for fair competition. Unlike major foreign countries that already regulate big data unfair practices by online platform companies through legislation and precedents, Korea has mainly implemented policies by linking data to privacy. Therefore, measures to regulate monopolies by collecting large amounts of data by platform companies have not yet been developed. Therefore, this paper examines the competitive restriction effect of data monopolization and analyzes regulatory trends in the United States, EU, Germany, and other countries that lead the digital economic market. Based on this, this paper would like to examine the m&a review of Delivery Heroes and Woowa Brothers Corp. to derive demand for improvement of 「Monopoly Regulation and Fair Trad Act」.
