STUDY ON TOTAL FACTOR PRODUCTIVITY OF NEW AGRICULTURAL BUSINESS ENTITIES IN AQUACULTURE INDUSTRY——BASED ON MICRO SUBJECT PANEL DATA AND SFA METHOD
New agricultural business entities are important forces in promoting the modernization of agriculture.Studying their production efficiency as well as analyzing and comparing the efficiencies of different types of new agricultural business entities are of great significance for promoting high-quality agricultural development and rural revitalization.Based on the panel data for 429 new agricultural operators of aquaculture production in China from 2018 to 2021,the stochastic frontier production function approach was applied to analyze total factor productivity(TFP)and decompose the driving factors of TFP.And the production technology efficiencies of three new types of agricultural business entities were analyzed and compared:leading enterprises,farmers'professional cooperatives,and family farms.Results indicated that the increase of the input of material,labor or fixed assets played a significant role in promoting output growth.In contrast,increasing service input had no significantly output.The source of TFP growth was technological progress.The contribution of returns to scale to TFP growth was negligible,while the decline of technical efficiency and allocation efficiency hindered TFP growth.The technical efficiency of each of the three types of new agricultural business entities showed idiosyncratic characteristics.When the group frontier was used as the benchmark,the technical efficiency of family farms was the highest.When the common frontier was used as the benchmark,the technical efficiency of cooperatives was the highest.When measured by the technical level represented by the technology gap ratio,the technical level of leading enterprises was the highest.Therefore,it is suggested to strengthen scientific and technological investment,improve technological efficiency,optimize the cost investment structure,and strengthen the alliance and cooperation of various new agricultural business entities.
