[Industry Focus]：The competition of the global digital economy is also the competition of the platform. In the future, we will focus on the platform to strengthen the digital economy industry system.

Strengthening the digital economy industry system with platform as the focus is the main feature of digital economy organization mode, and it is also an important starting point for China to build a digital, intelligent and international industrial chain supply chain innovation chain. Platform enterprises effectively combine factor resources through data, computing power and algorithms to promote accurate connection between supply and demand, which can effectively promote the formation of a higher level of dynamic balance between demand traction supply and supply creation demand. At the same time, platform enterprises can develop better and form digital industry ecology through building digital industrial chain, supply chain and innovation chain, which plays an important role in improving the quality of domestic circulation and smooth domestic and international double circulation.

In a sense, the competition of the global digital economy is also the competition of the platform, and the super-large platform has become the key factor for the competition and cooperation of various countries in the field of digital economy. Therefore, supporting platform enterprises to become bigger and stronger and focusing on the platform to strengthen the digital economy industry system will be an important work in the coming period.

On the one hand, the platform is the organizer of the industrial ecosystem. The platform can effectively integrate discrete element resources such as manufacturers, suppliers and service providers, and form an industrial division of labor model with data as the core element, network collaboration and co-creation and sharing, thus effectively improving the industrial resource allocation capability, collaborative development capabilities and service support capabilities form an industrial ecosystem that creates value together with upstream and downstream industry partners. The platform provides development space for enterprises in the ecological circle, breaks through the constraint that a single enterprise only relies on its own resources and has limited development capacity, and reduces the procurement and management costs of small and medium-sized enterprises, it plays an important leading role in promoting the digital transformation of traditional enterprises, the integration of manufacturing industry and service industry, and the deep integration of digital economy and real economy.

On the other hand, the platform can effectively solve the problem of compatibility between supply and demand. The platform not only integrates business flow, logistics, capital flow, data flow and other elements, but also realizes accurate matching between the supply side and the demand side through big data, it improves the information symmetry on both sides of supply and demand and the compatibility of products and services. Manufacturing enterprises can accurately judge the market according to platform data, reasonably arrange production capacity, accurately explore new consumption demand, develop and design new products and services with market prospects, and accurately grasp the credit situation of users, so as to build an efficient supply chain system and promote the integration and development of upstream and downstream industries. At the same time, the platform can also create a "long tail market" to promote consumption growth, so that many small, medium and micro enterprises and products with poor sales can find space in the market segments.

The platform has the ability to breed new general technologies and is the core organization for building industrial innovation chains. Generally speaking, the open platform can aggregate a large number of developers and service providers, and continuously release market demands such as technology development, operation and maintenance, thus promoting the formation of a technological innovation ecosystem, it provides soil for the large-scale growth of new technologies. At the same time, platform enterprises can also effectively realize collaborative innovation between manufacturers and R & D and design institutions. Platform big data can also provide important support for manufacturing enterprises to explore new market demands and improve new product development capabilities.

For example, the rapid development of cross-border e-commerce platforms has lowered the threshold of international trade, rapidly increasing cross-border trade with high frequency and small amount, and promoting international trade to be led by large enterprises, the transformation of bulk goods trade mode to a new mode of small and medium-sized enterprises' extensive participation, massive varieties and fragmented transactions has become an important engine driving the growth of foreign trade. In particular, the new generation of cross-border e-commerce has formed a full chain development model integrating goods trade and service trade, which not only provides cross-border commodity trade, but also provides relevant logistics, finance, information, A package of comprehensive foreign trade services such as credit investigation has formed a one-stop cross-border supply chain service, effectively solving the pain points of the development of small and medium-sized foreign trade enterprises and opening up the blocking points of the integration of domestic and foreign trade.

Some platform enterprises have the characteristics of openness, sharing and personalization, with low employment threshold, rich levels and strong ability to absorb employment, which can provide a large number of employment opportunities for workers with different educational levels and skill endowment, it plays an important role in promoting employment. In addition, some ultra-large-scale platform enterprises already have the public product attribute of digital infrastructure, which can provide more abundant public services for the society.

1. The innovation ability in key basic areas is relatively weak, and innovative talents are relatively scarce;

2. The development of industrial internet is relatively lagging behind, and the penetration rate of digital economy in China's service industry, industry and agriculture is lower than that of developed countries;

3. Insufficient open and sharing of platform data makes it difficult to effectively develop and utilize;

4. The supervision of the platform is lagging behind and cannot fully meet the needs of the rapid development of the platform economy.

In this regard, it is necessary to proceed from the strategic height of building a new competitive advantage of the country, adhere to the equal emphasis on development and standardization, grasp the law of platform economic development, establish and perfect the platform economic governance system, focus on the platform to strengthen the digital economy industry system.

The first is to effectively enhance the independent innovation ability of platform enterprises. To better stimulate the enthusiasm of platform enterprises and improve their participation in major national strategic planning and major scientific and technological projects in the field of digital technology, promote the opening of national basic scientific research resources such as large scientific devices to platform enterprises, and encourage platform enterprises to plus-sized investment in research and development.

The second is to strengthen the construction of digital talent team. Increase the setting of relevant disciplines in colleges and universities and vocational colleges, give full play to the strength of social training institutions and platform enterprises, vigorously carry out vocational training, and speed up solving the problem of shortage of professional and technical talents, at the same time, strengthen the introduction of global outstanding talents.

The third is to continuously enrich the application scenarios of industrial internet. China's ultra-large-scale consumer market and complete industrial system provide a solid foundation for cultivating platform enterprises with world competitiveness. In the next stage, we need to continue to improve platform enterprises and consumption, the ability of integration and penetration of industries and public service departments encourages the deep integration of platform enterprises and traditional industries, giving full play to their supporting role in promoting industrial digitalization and the advantages of efficient integration of innovative resources, promote the transformation and upgrading of traditional industries and further promote the development of industrial internet.

Fourth, build an effective mechanism to promote the open sharing of platform data. Massive data accumulated by platform enterprises is a very important strategic resource. It is necessary to speed up the establishment and improvement of relevant systems such as data confirmation, transaction, management, use, security rating, personal privacy protection, etc, promote all industries to share platform data resources according to law and build a data industry chain led by platform enterprises.

Fifth, accelerate the improvement of the regulatory system. We should focus on promoting the standardized operation and healthy development of platform enterprises, constantly improve the implementation rules of laws and regulations on anti-monopoly and anti-unfair competition, and clarify the compliance boundaries of platform enterprises' operation behavior, it is suggested plus-sized penalties for practices that infringe on consumers' rights and interests of the real economy and affect fair competition in the market. At the same time, it is necessary to strengthen the self-discipline of platform enterprises, guide platform enterprises to continuously improve their governance level based on big data and other technical means, and actively create a healthy industrial ecosystem with harmonious coexistence and innovation and inclusiveness.
