Sixty Theories of Digital Expo： Big Data Accelerates the Construction of ＂Community of Human Destiny＂

　　In the congratulatory letter from the Chairman of the Supreme Leader to the 2019 Digital Expo, "common" is a hot word: jointly seize the opportunities of digital, networked and intelligent development, promote the common development of all countries, and jointly build a community of human destiny.

　　The information technology revolution diffracted by "Big Data+"and "internet plus" is increasingly highlighting the accelerated arrival of the destiny community of "living together in the global village, you have me, I have you, and we are closely related". In his congratulatory letter to the 2019 Digital Expo, the Chairman of the Supreme Leader expressed ardent hope that:

　　We are willing to share the development opportunities of the digital economy with other countries and jointly explore new growth momentum and development paths by exploring new technologies, new formats and new models. I hope that delegates and guests will discuss the development and cooperation plan of big data industry around the theme of "innovation and development, counting the future" and make contributions to promoting the common development of all countries and building a community of human destiny.

　　Indeed, the rapid development of big data, Internet, cloud computing, etc., while bringing high-quality, high-speed, efficient and profitable dividends to human society, also comes with global issues and problems in data privacy and security, network chaos management and other aspects. By making good use of big data and other new technologies, China has set up a series of "digital platforms", set sail on the "digital silk road" and imagined the "digital future", which has accelerated the speed, quality and efficiency of building a "community of human destiny" and provided unique and attractive China experience, China’s plan and China’s wisdom for global governance and human development.

　　Building a platform: building an open, inclusive, mutually beneficial platform carrier with big data.The great idea of "community of human destiny" takes root, and it needs to build one online and offline interactive platform with the theme of "making friends, developing words and seeking win-win". With the help of Internet, big data, cloud computing and other information technologies, it is helpful to realize the "accurate pulse, all-round" and "finding the right topic without dead ends" in communication between countries; Taking advantage of the development of the digital economy is conducive to enhancing mutual identity, attraction and integration. In recent years, China has actively set up the "Belt and Road" international summit forum, Internet conference, big platform and big stage for digital fairs, and staged a series of wonderful performances of international digital economy, digital society and digital humanities communication and exchange, so as to make the grand idea of "community of human destiny" take root and bear fruit. The number fair held in Guiyang, the "Valley of Data", has become a "window" to publicize the concept of a community of human destiny. The "number fair" can be numerous when it is young, and the "international model" is becoming more and more sufficient because of its development concept of "internationalization, specialization, high-end, industrialization and sustainability".Digital Expo has increasingly become a "must-have" and "first choice" for big coffee makers in the global digital industry to get together to make friends, inspire and find opportunities. It is reported that Paul Romer, winner of Nobel Prize in Economics, Whitfield Duffy, winner of Turing Prize, and kevin kelly, a well-known writer, will all choose to attend the Expo in 2019. It can be seen that the theme forum of big data innovation and development represented by the number of fairs has become an effective measure to publicize and practice the concept of "community of human destiny".

　　Seeking development: achieving a rich world of common prosperity and mutual benefit with big data."Development is the last word". Big data and Internet technology are sharp tools to accelerate development. The scale and quality of the digital economy are booming, and the deep integration of the digital economy and the real economy has become an important source of vitality for global economic development. At present, the scale of digital economy in China has reached 31 trillion, accounting for about 1/3 of GDP. The industrial transformation is constantly upgrading, the employment space is constantly increasing, and the market players are constantly expanding, which has made great contributions to getting rid of the global economic downturn. According to a research report released by Shanghai Academy of Social Sciences this year, the current digital economy in China ranks second in the world, and its growth rate ranks first in the world, which may provide mature experience for the digital economy and social development of other late-developing countries. At the same time, through the construction of "Belt and Road", especially "Digital Silk Road", China has actively participated in the economic development pattern of countries along the route, and has been active in economic and trade exchanges between countries and regions along the route. China’s "Belt and Road" transcripts released by the Ministry of Commerce in 2018 show that the total import and export of goods between China and countries along the "Belt and Road" reached 1.3 trillion US dollars last year, a year-on-year increase of 16.3%; The opening of the Ma Youyi Bridge in Maldives, the opening of the Inner Mongolia Railway, the operational capacity of Gwadar Port, and the completion of the second phase of Hambantota Port. China’s successful experience and positive actions,The dream of a prosperous and prosperous rich world is being extended with the carrier of data technology.

　　Seeking peace: building a safe earth that is fair, just and free from fear with big data.As the saying goes, "Peace is bliss". Under the background of the world theme of peace and development, crisis frictions, regional conflicts and refugee problems in the international structure can be described as endless and frequently reported. How to make the international social governance structure form a good order in the new era and build a "safe world" and a "safe earth" to the greatest extent requires new ideas, new wisdom and new technologies. In this regard, China has taken the lead in promoting the construction of a smart society and a safe China by exploring the use of big data, cloud platforms and other technical means, effectively solving the long-term social governance problems that hinder fairness and justice, improving the level of social intelligent governance, and providing mature experience for other countries to follow in their safe construction. At the same time, the "One Belt, One Road" digital economic strategic alliance initiated by China enterprises such as Inspur has provided a world-class technology think tank of "data center+cloud service" by integrating the "data flow" and "information flow" of countries along the Silk Road, and formed overall technical solutions such as "smart finance", "smart investment" and "smart city", which has brought digital development dividends to relevant countries. By integrating ""Data flow", "rest flow" and "technology flow" can predict the possible difficulties, hot spots and focuses of global governance, and realize the fair and reasonable distribution of human, financial and material factors, which will certainly help to build a safe world that is fair and just and far from fear, and boost the sense of security satisfaction and acquisition of the community of human destiny.

　　Global governance in the digital age is inseparable from the full participation of data technology, and the rapid development of data technology will also bring the governance problem of "countless, chaotic". As General Secretary of the Supreme Leader pointed out: "Today, the Internet, big data, cloud computing, quantum satellites and artificial intelligence are developing rapidly, and the relationship between human life is unprecedented. At the same time, the number, scale and depth of global problems faced by mankind are unprecedented. The future and destiny of people all over the world are more and more closely linked. " Only by joining hands, making good use of big data technology to develop dividends and truly forming a community of responsibility, interests and destiny can human beings create a new situation of common and beautiful life of peace and development.
