Abstract

This study performs the spatial Durbin model (SDM) and threshold model to analyze the efficiency of agricultural green production following technological progress from 1998 through 2019. The SDM supports a nonlinear contribution of technological progress spillover to agricultural green total factor productivity (GTFP), exacerbated by upgrading agricultural structure. Moreover, the threshold model confirms that technological progress has a single threshold effect on agricultural GTFP with the rationalization of the agrarian system as a threshold variable; meanwhile, the contribution of technological progress to agricultural GTFP is less than that of agricultural total factor productivity. Out of the expanded application of dissipative structure theory in agricultural GTFP systems innovatively, this study reveals the urgency to strengthen the innovation of independent technology, lower the threshold for introducing technology, and optimize the agrarian structure in the long-term sustainable agriculture for the economies that are undergoing a similar development stage as China.

摘要

本研究采用空间 Durbin 模型(SDM)和门槛模型,分析了 1998 年至 2019 年技术进步对农业绿色生产效率的影响。SDM 支持技术进步溢出对农业绿色全要素生产率(GTFP)的非线性贡献,这一贡献受到农业结构升级的放大。此外,门槛模型证实,技术进步对农业 GTFP 具有单一的门槛效应,以农地制度的合理化作为门槛变量;同时,技术进步对农业 GTFP 的贡献小于农业全要素生产率。本研究创新性地将耗散结构理论扩展应用于农业 GTFP 系统,揭示了在类似中国发展阶段的经济体中,加强自主技术创新、降低技术引进门槛以及优化农业结构的紧迫性,以实现长期可持续农业。
