Promote quality change with efficiency change and power change.

　　When attending the deliberation of the Jiangsu delegation at the First Session of the 14th National People’s Congress, General Secretary of the Supreme Leader stressed: "We must unswervingly deepen reform and opening up, deeply change the development mode, promote quality change with efficiency change and dynamic change, and accelerate the formation of a sustainable and high-quality development system and mechanism." The important exposition of the Supreme Leader General Secretary profoundly clarified that quality change is an important goal to achieve high-quality development, and clearly pointed out that efficiency change and power change are effective means to promote quality change, which provides a fundamental basis for us to promote high-quality development on a new journey.

　　At present, China has entered the stage of high-quality development, and the people’s demand for high-quality products and services is growing stronger and stronger. It is more urgent to change the development mode, optimize the economic structure and change the growth momentum. It is necessary to put the quality of development in a more prominent position, improve the quality and efficiency of the supply system, and accelerate the leap from a low-level supply-demand balance to a high-level supply-demand balance. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has complied with the changes in China’s development stage, development conditions and development pattern, made major strategic decisions to promote high-quality development, unswervingly pushed forward supply-side structural reforms, and promoted the quality of China’s economic development. On the new journey, it is necessary to continuously meet the people’s yearning for a better life and realize the grand goal of building a socialist modern power in an all-round way, and it is also necessary to continuously improve the quality and efficiency of China’s development. Promoting quality change, in a narrow sense, requires breaking through the quality bottleneck that restricts industrial development and improving the quality of products and services; In a broad sense, it is required to comprehensively improve the development level of all aspects of the national economy and cultivate new development advantages centered on technology, standards, brands, quality and services.

　　Only by promoting efficiency change can we effectively promote quality change. The core of efficiency reform is to optimize the allocation structure of factors, improve the efficiency of input and output, and strive to improve the quality and efficiency of economic development in a shorter time, in a deeper level and in a wider field. The high-level socialist market economic system provides an important institutional guarantee for realizing efficiency change. China’s socialist market economic system is constantly improving, but there are still shortcomings and weaknesses such as imperfect property rights system, imperfect fair competition system and lagging development of factor market. We should further emancipate our minds, adhere to and improve the basic socialist economic system, promote a better combination of effective market and promising government, establish a unified national market with high efficiency, standardization, fair competition and full opening, open up the key blocking points that restrict the economic cycle, make all links of production, distribution, circulation and consumption smoother, promote the smooth flow of commodity factor resources in a wider range, and provide high-level institutional guarantee for accelerating the efficiency change.

　　Only by realizing the dynamic change can the economic quality advantage be significantly enhanced. The core of power change is to accelerate the conversion of old and new kinetic energy and improve total factor productivity. Although China’s economic aggregate ranks second in the world, there are still problems of being big but not strong, which are mainly reflected in the lack of original innovation, the low-end industry as a whole, and the dependence on imports of some high-end technologies and products. In this regard, we must give full play to the role of science and technology as the primary productive force, the role of talents as the primary resource, and the role of innovation as the first driving force for development, and strive to open up new fields and new tracks for development and shape new kinetic energy and advantages for development. In particular, it is necessary to strengthen scientific and technological innovation in the manufacturing sector, gather strength to carry out original and leading scientific and technological research, resolutely win the tough battle of key core technologies, and accelerate the implementation of a number of major national scientific and technological projects with strategic, overall and forward-looking features. At the same time, we should pay attention to expanding international scientific and technological exchanges and cooperation, strengthen the construction of an international scientific research environment, and form an open and innovative ecology with global competitiveness.

　　On the new journey, faced with the unavoidable contradiction in promoting high-quality development, we should not only lead the comprehensive deepening reform with the new development concept, but also provide institutional guarantee for the complete, accurate and comprehensive implementation of the new development concept through comprehensive deepening reform, focus on cracking down on deep-seated institutional obstacles, deeply transforming the development mode, promoting quality change with efficiency change and dynamic change, constantly breaking through the bottleneck of high-quality development, and effectively solving the problem of insufficient development imbalance.
