Green Total Factor Productivity of Agriculture under the Constraint of Carbon Emissions-An Empirical Analysis Based on Panel Data of Guangdong Province

Abstract

Green agricultural development is the connotation and requirement of high-quality agricultural development. The measurement and research of green total factor productivity (GTFP) of agriculture has important references for measuring the level of high-quality agricultural development. Guangdong Province is divided into four regions, namely, the Pearl River Delta region, the east, west and north regions. The city-level data of Guangdong Province in 2007-2017 is used to measure the agricultural GTFP in Guangdong Province, and the agricultural GTFP is analyzed from the time trend and spatial distribution, the results show that: (1) The agricultural GTFP in Guangdong Province shows an upward trend year by year, the technical improvement and technical progress are the main sources of agricultural GTFP growth, but the growth rate is on the decline; (2) The level of agricultural green productivity varies among the four regions in Guangdong Province. The Pearl River Delta region ranks the top, followed by the north Guangdong region, the east Guangdong region and the west Guangdong region. However, the overall level of these three regions is not significantly different. (3) There are also great differences in agricultural GTFP levels among cities within the four regions. Based on the above conclusions, some suggestions to improve the agricultural GTFP in Guangdong Province are put forward: (1) always adhering to the"five in one"overall strategic goal, implementing the rural revitalization policy, following the green development concept proposed by the Party Central Committee, paying attention to constraints of environmental factors on agriculture, and effectively promoting the negative growth of fertilizer and pesticide use; (2) Transforming the mode of agricultural production and operation and promoting the progress of green science and technology in agriculture in many aspects, including increasing financial support for green science and technology research and development in the agricultural field and establishing a system for the training and introduction of agricultural talents; (3) Implementing the strategy of coordinated regional development, giving play to the effect of agglomeration and amplification, and promoting the coordinated development of green agricultural regions.
