The development of "agriculture, rural areas and farmers" urgently needs the construction of innovative theory.

China's "three rural issues" is an indescribable topic, which involves a wide range, rich connotation, complex situation and rapid change, which is unparalleled in many other fields. In recent years, the economic situation at home and abroad has fluctuated, and China's economic development has entered a new normal, which has a bearing on the "three rural issues" of the Party's goal of "two centuries". In particular, it is necessary to constantly explore and summarize in theory and practice, constantly refine and sublimate, and constantly innovate and research. Under the new situation, the principal contradiction of agriculture has changed from total shortage to structural contradiction, which is mainly manifested in the coexistence of periodic oversupply and insufficient supply. promoting agricultural supply-side structural reform has become the main direction of agricultural policy reform and improvement. In the new historical stage, in the face of many challenges of agricultural and rural development, the research and exploration of the "three rural issues" need innovative thinking, change of ideas, broaden their horizons and go deeper. Tamping the agricultural foundation, improving agricultural quality, efficiency and competitiveness, promoting the coordinated development of new urbanization and new rural construction, promoting the continuous increase of farmers' income, and promoting accurate poverty alleviation and poverty alleviation can neither reduce the efforts to grasp agriculture, rural areas and farmers, nor reduce grain production capacity.

What's more, the interests of farmers should not be harmed, which is an arduous and complex system engineering, which urgently needs pioneering practical exploration and innovative theoretical construction.

In the 13th five-year Plan, the state puts "vigorously promoting agricultural modernization" in a prominent position, and first mentions that agriculture is the basis for building a moderately prosperous society in an all-round way and realizing modernization. It is clearly pointed out that it is necessary to speed up the transformation of the mode of agricultural development, develop various forms of moderate scale operation, and play a leading role in the construction of modern agriculture. We will strive to build a modern agricultural industrial system, production system, and management system, improve agricultural quality, efficiency and competitiveness, and promote the development of grain economy and feeding, the combination of agriculture, forestry, animal husbandry and fishing, the integration of planting and breeding, and the integration of primary, secondary and tertiary industries. take the road of agricultural modernization with high output efficiency, product safety, resource conservation and environment-friendly. The blueprint has been drawn and efforts need to be made to implement it.

The China Rural Research Institute of Tsinghua University, founded in 2011, is a university-level scientific research institution of Tsinghua University and an interdisciplinary research platform for agriculture-related disciplines, focusing on the overall, strategic and forward-looking issues in the field of China's "agriculture, rural areas and farmers". Committed to building a first-class think tank to serve the country's "three rural" decision-making, an important base for training high-quality talents in agriculture-related disciplines, and a first-class academic research platform for the prosperity of China's rural reform and development theory. A large number of people are gathered here.

People of insight who are engaged in theoretical research and practical exploration of agriculture, rural areas and farmers, they continue to speak on this platform, contribute wisdom to serving "agriculture, rural areas and farmers" and make frequent suggestions for national decision-making.

Comrade Liu Qi's new book "Tsinghua eight lectures on Agriculture, Countryside and Peasants" is a speech on this platform, and it is also the first personal speech monograph published since the establishment of the China Rural Research Institute of Tsinghua University. He has held eight lectures on this platform in a year, with rich content, large amount of information, unique views, profound insights, broad vision, and witty remarks, which is also the consistent feature of Comrade Liu Qi's articles, with a unique style in the field of agriculture, rural areas and farmers. I believe that whether they are theoretical researchers of "agriculture, rural areas and farmers", or practitioners of the work of "agriculture, rural areas and farmers", or students, they will have some insights, inspiration and benefits after reading. We hope that more people of insight will come to this platform to exchange ideas, discuss Tao, teach karma, answer questions, condense wise philosophies in the interaction, burst out the spark of innovation in the collision, and offer suggestions for the prosperity and innovation of China's rural reform and development theory.
