Analysis on the Growth and Convergence of Agricultural Green Total Factor Productivity in Guangxi

Abstract

This paper uses DEA-SBM super-efficiency model and GML index to calculate the agricultural green total factor productivity (AGTFP) of Guangxi from 2014 to 2020, and analyzes the convergence of AGTFP and its influencing factors. The study finds that: First, Guangxi's AGTFP increased by 5.42% annually, mainly driven by the agricultural green technology progress; Second, the growth of AGTFP in different regions exists heterogeneous, and the growth rate of western Guangxi ranks first in Guangxi; Third, the AGTFP in Guangxi shows a state of first σ converges and then σ diverges, there is absolute β convergence in AGTFP in Guangxi, this phenomenon exist in northern Guangxi, central Guangxi, southern Guangxi and eastern Guangxi, but there is no absolute β Convergence in western Guangxi ; Fourth, agricultural structure inhibits AGTFP, while the level of fiscal support for agriculture promotes AGTFP.
