Author: Lei Ming (Professor of Guanghua School of Management, Peking University, Dean of the Rural Revitalization Research Institute, Peking University) pointed out in the report of the 20th National Congress of the Communist Party of China that Chinese path to modernization is a modernization in which people and nature coexist in harmony. In the new era and new journey, we must firmly establish and practice the concept of "green water and green mountains are golden mountains and silver mountains", continue to promote green development, promote the harmonious coexistence of man and nature, and promote the construction of a beautiful China. Chinese path to modernization is a modernization with a huge population. China's population of more than 1.4 billion has marched into a modern society as a whole, which is larger than the total population of the developed countries. It is unprecedented in difficulty and complexity. Among them, hundreds of millions of farmers in rural areas can not be ignored. It can be said that without their modernization, there would be no overall modernization. The harmonious coexistence of man and nature in agriculture and rural areas is related to the overall situation of national green development and national rejuvenation. Building an ecological village is an inevitable requirement for rural revitalization and building a beautiful China. In combination with the implementation of the three-year action plan for rural human settlements improvement and the rural revitalization strategy, we should adjust measures to local conditions, implement precise policies, do one thing after another, and work year after year to build a beautiful ecological and livable village, so that farmers can have more sense of gain and happiness in rural revitalization. Since the start of the construction of beautiful villages, various regions have started the construction of clean villages around their homes, water sources and rural areas; Promote the construction of ecological villages around the "three modernizations" of village greening, drinking water purification and road hardening; The construction of livable villages will focus on enriching industries, benefiting services and facilitating infrastructure. The country has anchored the strategic goal of building a beautiful China, continued to carry out ecological rural construction, and through continuous efforts, made the countryside look new, which has opened a good situation for promoting rural revitalization and sustainable development of rural economy and society. Building a beautiful countryside is both a tough battle and a lasting battle. Deeply, persistently and deeply promote the construction of ecological villages, with heavy tasks and great pressure. We must strengthen our sense of hardship and cultivate bottom line thinking to better cope with the complex situation of ecological environment construction, achieve "people are rich" and "ecological beauty", and create a beautiful ecology and economy. We should firmly establish the awareness of a community of life, actively practice the concept of "green water and green mountains are golden mountains and silver mountains", and promote the steady improvement of the quality of rural ecosystem construction. We should make full use of the advantages of mountains, rivers, countryside, humanities and other resources, rely on natural advantages to develop characteristic industries, and expand the village economy. By vigorously developing green ecological industries, actively developing modern agriculture, rural tourism and other industries, we will explore the formation of a "ecological+" composite economic development model, cultivate a new driving force for green development in which people and nature coexist harmoniously, strengthen and expand the "cake" of ecological economy, and provide a new driving force for rural revitalization. To build an ecological village, we need to further play the role of systems and mechanisms. On the whole, ecological village construction should be based on the existing top-level design and policy introduction
