During the 13th Five-Year Plan period (2016–2020), China has made great achievements in the three major aspects of targeted poverty alleviation through industrial development, development of special rural areas, and equalization of urban and rural infrastructure and basic public services. In addition, the important experience of multi-agent participation, multi-mode guidance, and multi-line promotion has been accumulated in the individual, regional and urbanrural dimensions. However, there remain some deficiencies, such as low policy efficiency, poor matching ability, and prominent structural problems. At the beginning of the 14th Five-Year Plan (2021–2025), the task of enriching farmers through sharing has been faced with many challenges, such as major changes in the focus of poverty governance, greater numbers of restraints on the development of special rural areas, and heavy responsibilities of equalizing urban and rural infrastructure and basic public services. Therefore, it is necessary to acquire a profound understanding of the new development concept, and to continuously enrich farmers through sharing in terms of accelerating the improvement of the institutionalized poverty reduction system in the new era, actively building a green development system of agriculture and animal husbandry in special rural areas, and striving to create a fair and complementary urban and rural infrastructure and basic public service system.展开更多
