It has opened a new journey of China's economic modernization. Looking back over the past 10 years, China's economic construction has made remarkable achievements. Over the past 10 years, the GDP has exceeded the threshold of one million billion yuan, with an average annual growth rate of 6.6%; The per capita GDP reached 12000 US dollars, nearly double that of 2012. China has become the main engine of world economic growth, with an average contribution rate of more than 30% to global economic growth; We have achieved a higher level of opening up, and the introduction of foreign capital and foreign investment have steadily ranked among the world's top. In the past 10 years, China has realized the power transformation from factor driven, investment driven to innovation driven. The average annual wage of employed people has increased significantly, and a large number of landmark achievements have emerged, realizing historic, overall and structural changes. In the past 10 years, China has historically eliminated absolute poverty and has taken advantage of the situation to enter a new stage of rural revitalization and common prosperity. After 10 years of rapid development, China's economy has shown strong growth resilience and huge development potential, and the country's economic strength, scientific and technological strength and comprehensive national strength have reached a new level. China is already the world's second largest economy, with a population of more than 1.4 billion, more than 400 million middle-income groups, and all the industrial sectors in the United Nations industrial classification. Under the impact of the complex international situation and the epidemic situation, China will remain the only major economy to achieve positive economic growth in the world in 2020. In 2021, the volume of imports and exports of goods will rise steadily, maintaining a strong attraction for international capital and high-quality elements. The achievements are hard won, and we still need to work hard to maintain sustained and stable economic growth. At present, the key to achieving economic stability and growth is to enhance market expectations and boost the confidence of enterprises and consumers on the basis of stabilizing the economic market and minimizing the uncertainty faced by economic development. Influenced by international geopolitics, epidemic situation and other factors, the value chain of the global industrial chain supply chain has been restructured at an accelerated pace. Only comprehensive measures can consolidate China's pivotal position in the global production network and economic and trade system. In the medium to long term, the contradiction in China's development is mainly reflected in the quality of development. In the process of economic modernization, we should fully, accurately and comprehensively implement the new development concept, actively change the development mode, consolidate the foundation of development, balance development and security, continue to enhance new advantages in international cooperation and competition, and firmly promote the construction of a modern power. First of all, we should complement the weaknesses of core technologies and consolidate the foundation for scientific and technological self-reliance. We will improve the independent innovation system on the basis of technology, enterprises and talents, strengthen institutional advantages with problem orientation and top-level design as the driving force, focus on tackling key technologies and cutting-edge technologies, and accelerate the upgrading from technology introduction to independent research and development,
