"天府粮仓"粮食全要素生产率测度与提升路径
Measurement and Promotion Path of Total Factor Productivity of Grain in the"Tianfu Granary":Based on the Panel Data of Sichuan Province from 1998 to 2023
摘要
Abstract
Accurately measuring the total factor productivity(TFP)of grain production in the"Tianfu Granary"and revealing its growth sources and influencing factors are of great significance for Sichuan Province to build a high-level"Tianfu Granary",strengthen regional stable grain supply capacity,and consolidate the foundation of national food security.Based on panel data of 21 cities(prefectures)in Sichuan Province from 1998 to 2023,this study adopted the DEA-Malmquist index method to calculate and decompose grain TFP,and constructed an econometric model to identify the possible mechanisms affecting grain TFP.The results showed that:from 1998 to 2023,the grain TFP of the"Tianfu Granary"showed an overall growth trend;technological progress constituted the primary driving factor of grain TFP growth,and the improvement of technical efficiency lagged behind the pace of technological progress;the growth of grain TFP,technological progress and technical efficiency change in the"Tianfu Granary"exhibited significant regional heterogeneity;the implementation of the"Tianfu Granary"strategy had substantially increased grain TFP;grain yield per unit area,grain sown area per labor,grain research investment per unit area and effective grain irrigation rate had positive impacts on grain TFP,while total mechanical power per labor and the degree of grain production structure adjustment had negative impacts,and regional economic development level had no significant impact on grain TFP.Therefore,it's suggested improving the multi-level collaborative governance mechanism,establishing a"dual-wheel drive"pattern of technological progress and technological efficiency,refining the agricultural science and technology innovation mechanism,and promoting moderately large-scale planting,to promote the optimization and enhancement of grain TFP in the"Tianfu Granary".关键词
