Recently, China Unicom subsidiary and Tencent subsidiary set up a new hybrid company to jointly develop content distribution network and edge computing business, which attracted public attention. The author believes that the basic policy of China's socialist market economy is clear, that is, state-owned capital, collective capital, private capital, foreign capital and mixed capital should be protected according to law, and there is no need to replace one type of capital with another. Of course, for areas that are related to the national economy and the people's livelihood, major infrastructure and important basic resources, we should adhere to the principle of public ownership. On this basis, we will give full play to the decisive role of the market in resource allocation and give better play to the role of the government. We should not only act in accordance with market rules, but also give full play to the role of government supervision and guidance. In recent years, the rapid development of the platform economy has indeed brought about some problems involving monopoly, winner take all, information security and user privacy security, which need to be solved through improved supervision. However, various types of capital are still encouraged to shape business forms and compete fairly in accordance with legal provisions and market needs. Therefore, the cooperation between China Unicom and Tencent in business development is just an innovative way to give full play to the advantages of basic telecom enterprises and Internet platforms. It is worth expecting that different capitals can achieve win-win results by establishing a standardized corporate governance system. This is conducive to breaking the ownership isolation of "well water does not interfere with river water", which is a good thing. Capital has the characteristic of pursuing profits. Where there is a market, capital will flow to where it is. This is the basic law. To build a socialist market economy, we should not only give play to the function of capital to gather resources and develop markets, but also restrict its disorderly expansion and the negative effect of squeezing other production factors. The platform company responds to the market demand and develops products and services suitable for the market demand, while the three major telecom operators provide infrastructure and channel services and operate related derivative services, which are interdependent. This time, China Unicom and Tencent formed a joint venture based on their own needs: China Unicom has edge computer rooms, network connectivity and other infrastructure resources, and Tencent has cloud technology and ecological advantages, which can complement each other. Both Tencent and Unicom are looking for new market incremental space and value. Putting aside the differences in capital attributes, it is a positive approach for all market entities to seek cooperation according to their respective industrial advantages. Moreover, the integration of the Internet, telecommunications network and radio and television network has long been a fact, and the integration of development is the trend of the times. There is a lot of space for exploration and practice as to what kind of business type and business model to shape, what kind of capital, technology, personnel and other elements are needed, and how to organize these elements. The property of capital should not become a fundamental obstacle to the combination and cooperation of market players. China is in the accelerated stage of building a modern industrial system. Building a network power and a digital power requires the active participation of all parties and subjects. As the main carrier of the public economy, the fundamental requirement for large state-owned enterprises to cooperate with enterprises controlled by private capital is to comply with the law, comply with market rules and provide better products and services for the people. This cooperation is in line with the basic law of optimizing the allocation of capital and other production factors, as well as the basic requirements of the socialist economy to pay more attention to fairness and justice. We will promote industrial development and safeguard the safety of public interests, while also conducting supervision and guidance according to law. Now there's a mistake
