A few days ago, the 2022 China International Trade in services Fair came to an end. The 10 years of China's trade in services have witnessed the rapid development of China's trade in services. From 2012 to 2021, the added value of China's service industry increased by 1.49 times, and imported services totaled more than $4 trillion, further strengthening its super large-scale market advantage. At this year's service trade fair, a number of high-speed rail cutting-edge products, including new intelligent EMUs, not only refreshed the "China speed" and demonstrated the strength of "made in China", but also redefined the high-quality and efficient "China service", making "China service" go global. Trade in services is a key area for the wider opening up of the world. Throughout the history of the development of human society, the world economy thrives when it is open and declines when it is closed. In recent years, in the face of the spreading trend of protectionism and anti globalization, trade in services has increasingly become a new engine for global opening and development. From 2011 to 2020, the global trade in services grew at an average annual rate of 2.3%, 0.9 percentage points higher than the trade in goods. The growth rate of some types of trade in services, such as it services, business services and intellectual property royalties, was two to three times that of trade in goods. Trade in services is an important driving force for China's stable economic growth. Business logistics, cultural tourism and finance are the traditional areas of service trade, which have radiated new vitality in the digital economy era. For example, the cross-border e-commerce industry is in full swing. At the same time, cross-border data flow, low-carbon technology patent trading and other emerging areas of service trade have also made rapid development. From 2012 to 2021, China's personal culture and entertainment services, telecommunications computer and information services, and intellectual property use fees increased by 5.8 times, 3.2 times, and 2.1 times respectively; The scale of offshore service outsourcing increased by 2.9 times, and the service outsourcing industry absorbed 11.27 million jobs. Trade in services can improve the quality of industrial development and the level of economic modernization. The foundation of enriching the people and strengthening the country is really industry. When we discuss high-end manufacturing, we are also discussing modern service industries to a large extent, such as technology, intellectual property rights, data elements, etc. Trade in services is not only trade in traditional "services", but also trade in "value-added content of high-end manufacturing". For example, the operating system, appearance design and brand logo of a foreign mobile phone brand account for more than half of its retail price. Moreover, trade in services can also help meet people's diversified demand for services. For example, since 2020, the online fitness industry has risen against the trend, and the number of users of "daily yoga", a domestic online yoga teaching platform integrating Indian culture, has exceeded 60 million, covering more than 200 countries and regions. Therefore, trade in services not only carries the banner of foreign trade, supports the macro data of foreign trade, foreign investment and import and export, but also promotes the high-quality development of various industries of the national economy. Trade in services is constantly improving the global and domestic development patterns. Trade in services is not only related to trade, but also to the economic growth momentum and high-quality development level of various regions. For many years, the World Trade Organization (WTO) has taken trade in services as the main negotiating content, including the regional comprehensive economic partnership agreement (RCEP), the comprehensive and progressive trans Pacific Partnership Agreement (cptpp), and so on
