It can be seen that promoting the national strategy to try first at the local level and actively giving full play to the traction of the national strategy on high-quality development is an important way for our party to govern the country and government. It is also a major strategic measure for China to implement the new development concept, build a new development pattern and promote high-quality development based on the new development stage. 1. National strategy is an important way for our party to govern the country and manage the government In the early stage of reform and opening up, in view of the internal and external environment and conditions faced by China's economic and social development at that time, we gave full play to the exemplary role of "special affairs and special handling" of the special zone, and explored and accumulated very important valuable experience for promoting reform and opening up and promoting economic and social development. Since the 18th National Congress of the Communist Party of China, China has entered a new historical stage of comprehensively deepening reform. The environment, conditions, tasks and objectives to be achieved are very different from those in the early stage of reform and opening up. Facing the problems of how to promote comprehensively deepening reform and achieve a higher level of opening to the outside world in the new era, how to accelerate the formation of a market-oriented, legalized and international business environment, and how to promote deeper comprehensive and integrated institutional innovation, There is an urgent need to combine the top-level design of reform and opening up with grass-roots practice and innovation, and combine the national development strategy in the new era with the internal driving force of local development, so as to form more innovative new ideas, new schemes and new practices. To this end, the CPC Central Committee has made a series of development strategic planning and top-level design of reform and opening up, and put these major national strategies on the local pilot, providing replicable and popularized experience for the development of reform and opening up throughout the country. Practice has proved that giving full play to the role of national strategy in leading local high-quality development, promoting national strategy to try first in local areas, and actively exploring replicable and popularized experience is an effective path and an important way for our party to govern the country. On the one hand, it can give play to the demonstration and leading role of pilot areas, explore new paths and accumulate new experience for deepening reform and opening up; On the other hand, it can provide new opportunities and inject new impetus into local development. At present, China has entered a new stage of comprehensively deepening reform. The reform should be more systematic and integrated. The complexity and arduousness of comprehensively deepening reform determine that some major reforms must be tried first in places with conditions and foundation, and then copied and popularized nationwide after exploring the laws and accumulating experience. Of course, some innovative policies and practices that have been proved to be positive and effective in practice can also be further upgraded to top-level design. 2. The national strategy has achieved significant positive results in local trials The national strategy has been tried first in local areas and promoted the organic combination of national strategy and local development. It has formed a very vivid practical example all over the country and achieved many significant and positive results. Especially since the 18th National Congress of the Communist Party of China, including the coordinated development strategy of Beijing, Tianjin and Hebei, the integrated development strategy of the Yangtze River Delta, the Great Bay area strategy of Guangdong, Hong Kong and Macao, the ecological protection and high-quality development strategy of the Yellow River Basin and many other development strategies at the national level, by choosing to try first in some places with conditions and foundation, paying attention to local exploration and innovation, paying attention to the practical creation of the people, and then constantly summing up experience, It has played an important exemplary and leading role. From the perspective of practice, all pilot regions can consciously take undertaking the national strategy as their mission and task, organically combine the implementation of the national strategy with giving play to local enthusiasm, pay attention to transforming the national strategy into new advantages of local development, constantly promote local high-quality development in serving the overall situation of national reform and opening up, and actively provide replicable and popularized experience for national development in the pilot. For example, Shenzhen has actively played the leading role of the national strategy of building a leading demonstration area of socialism with Chinese characteristics, based on the reality of local development, took the lead in forming a new pattern of comprehensively deepening reform and comprehensively expanding opening-up, actively explored and better implemented the Guangdong Hong Kong Macao Bay strategy, innovated and enriched the new practice and experience in the development of the cause of "one country, two systems", and provided strong support and practical demonstration for realizing the Chinese dream of the great rejuvenation of the Chinese nation. For another example, in accordance with the strategic deployment and requirements of "becoming the pioneer of higher-level reform and opening up, the vanguard of building a socialist modern country in an all-round way, highlighting the practice example of" four self-confidence "and better showing the Chinese concept, Chinese spirit and Chinese road to the world", Shanghai takes accelerating the construction of a modernization leading area in Pudong as the national strategic traction and is based on a new round of high-level reform and opening-up in Pudong New Area, Take the lead in exploring new experience in building a modern country through high-level reform and opening up, actively create a window for building a socialist modern country in an all-round way, and play a pioneering role in opening a new journey of modernization for the whole country. For example, Zhejiang shoulders the national strategy of promoting high-quality development and building a demonstration area for common prosperity, takes the lead in taking the solid promotion of the construction of the demonstration area for common prosperity as an important window to comprehensively display the advantages of the socialist system with Chinese characteristics in the new era, explores effective ways to solve the main social contradictions in the new era, and establishes a target system, work system and policy system for bringing wealth first and then wealth, and solidly promoting common prosperity, Strive to provide a provincial example for the country to promote common prosperity. In addition, there is the construction of the Yangtze River Delta ecological green integrated development demonstration area, which is also exploring the way for the development of national regional economic integration. Vivid cases and practical innovations in this regard have sprung up and are numerous. On the whole, the national strategy has been tried first at the local level, closely combined the national strategy with local development, achieved significant and positive results in implementing the national development strategy and serving the overall development situation, and also provided us with some new enlightenment. On the one hand, the national strategy tries first in local areas, which fully demonstrates the advantages of China's socialist system and deeply reflects the practical characteristics of the modernization of China's governance system and governance capacity in the new era. The national strategy leads to local high-quality development, which helps to fully mobilize the enthusiasm of the central and local governments, give full play to the dual positive role of the top-level design of the national strategy and the innovative development of grass-roots practice, and effectively combine the implementation of the national will with the dynamic mechanism of local high-quality development. On the other hand, the practical achievements and experience of the national strategy in leading local high-quality development also provide an important source of practice for the construction of socialist political economy with Chinese characteristics. The construction of socialist political economy with Chinese characteristics must be based on China's development practice, summarize China's development experience, refine China's development theory, and form China's discipline system, academic system and discourse system. The practice and experience of China's national strategy in local first try and leading local development reflect the profound grasp of the important relationship between the central government and local governments, top-level design and grass-roots practical innovation, comprehensively deepening reform and the "experimental field" mechanism. The experience gained is very worthy of profound explanation in theory and scientific expression in academia, So as to make positive contributions to accelerating the construction of socialist political economy with Chinese characteristics. 3. Give full play to the leading role of the national strategy and accelerate the realization of high-quality development Giving full play to the positive role of national strategy in driving local development and promoting China's high-quality economic development has become an important way for our party to govern the country and government. It has also made considerable achievements and experience in practical exploration. In order to give better play to the role of national strategy in guiding local development, the following aspects deserve further attention: Pay more attention to the superposition advantages of various national strategies to gather and release greater vitality and impetus for local development. In the process of embedding national strategies into local development, some places may undertake multiple national strategies at the same time. In this case, local governments should pay attention to giving full play to and making use of the superposition advantages of many national strategies to prevent the "fragmentation" of many national strategies in practice; We should adhere to systematic and strategic thinking, focus on high-quality development, give full play to the leading role of integrated reform and innovation, broaden the space and fields of reform pilot and innovation and development, ensure that various national strategies cooperate with each other, form joint forces, promote the superposition advantages of national strategies, gather and release greater vitality and motivation for local development, and ensure the comprehensive and systematic implementation of national strategies. Pay more attention to the organic unity and mutual promotion of national strategy and local practice and innovation, and further deal with the internal relationship between top-level design and grass-roots innovation. Under the guidance of the national strategy and top-level design, take the initiative to give full play to the role of local governments as pioneers, adhere to local realities, stimulate the internal motivation of cadres and people to start businesses, form a trial and error tolerance mechanism, mobilize all enthusiasm and creativity, ensure the implementation of the national strategy in place, scientifically embed local development and form a new driving force to promote local high-quality development. We will strive for a wider range of national and local strategies to promote, replicate and innovate, and play a greater role in promoting national and local development. The purpose of the national strategy is to take the lead in forming replicable and replicable institutional innovation experience. On the basis of trial first, we should comprehensively and timely summarize and refine the new experience and new practices of local practical innovation and development, further expand the scope of pilot projects and areas that can be replicated and popularized, strive for the replication and popularization of national strategies and development experience in more places, and achieve greater pilot results. Pay more attention to the internal relationship between comprehensively deepening reform and national strategy, and constantly release the system integration effect of comprehensively deepening reform and the major traction role of national strategy. The core content of promoting the national strategy is to comprehensively deepen the reform. Therefore, it is bound to be inseparable from the deep-seated system and mechanism reform. It is bound to reflect and release the system integration effect of the deep-seated reform, especially to fundamentally solve the development problems and system bottlenecks with comprehensive, in-depth, systematic and integrated system innovation. In addition, in the process of promoting national strategy pilot, we should also pay attention to changing government functions and improving administrative efficiency. In particular, we should pay more attention to the organic connection between departments and institutions, functions and policies of the central government and local governments, give full play to the integrated administrative efficiency, and ensure the organic unity of national strategy and local pilot.
