Redefinition of "Agricultural Green Productivity" and "Green Total Factor Productivity" under the Constraints of Carbon Emissions—A Review of Chinese Agricultural Green Productivity Studies

Abstract

Agriculture, as a basic industry in China, is a major event affecting national economy and people's livelihood. Agricultural production efficiency is an important indicator for measuring the overall agricultural productivity, and it has been a research hotspot in academia. For a long time, scholars at home and abroad have used different methods to measure China’s agricultural production efficiency from different aspects, but only based on traditional basic factors such as capital, labor and land, and ignored resources and the environment Impact on agricultural production. In fact, resource consumption and environmental degradation have become difficult problems facing agricultural development in various countries, and are an important issue that hinders the sustainable and healthy development of economy and society. China's agricultural economic growth has achieved such great achievements. On the one hand, it has relied on the gift of nature to obtain rapid development. On the other hand, China's agricultural economic growth is based on the cost of natural resource consumption and environmental pollution. Especially with the increasing use of chemical fertilizers, pesticides and agricultural films, it has brought serious agricultural non-point source pollution problems. At the same time, the form of China's carbon emissions is not optimistic. Data show that agricultural carbon emissions account for about 17% of the total greenhouse gas emissions in the country, and the form will be more severe in the future. There is no doubt that China's agricultural economic development model urgently needs transformation and development, and cannot be based on the cost of resource consumption and environmental pollution. In order to achieve sustainable agricultural development, Chinese agriculture must take into account the coordinated and coordinated development of economic growth, resource conservation, and environmental protection. By combing the literature on agricultural production efficiency, it is found that many scholars have focused their perspectives only on a specific industry, lacking a policy path to guide the entire industry and regional industry to improve ecological efficiency. This article will comprehensively sort out relevant theories and redefine "agricultural green productivity" and "green total factor productivity" in order to lay the foundation for future related research.
