The Role of Government Policies in the Adoption of Conservation Tillage in China: A Theoretical Model
首发时间:2015-12-28
Abstract:In this paper, the author constructs a theoretical model to explain a farmer's adoption decision of conservation tillage. Conservation tillage is a production method that leaves more residues on the field after harvest. It is typically considered both cost-reducing and eco-friendly, with the multi-benefits of controlling soil erosion, increasing soil organic matter, conserving soil moisture, and reducing labor and energy costs. However, the adoption rate of conservation tillage systems is very low in China. The goal of this study is to explore potential reasons behind the low adoption rate of conservation tillage in China. This study considers factors specific to a typical farmer in rural China. These factors include small farm size, low ability of learning and adaptation, and low vulnerability to risk. Using this model, the author discusses alternative policy tools that can help improve a farmer's incentive to adopt conservation tillage.

论政府政策在保护性耕作技术采用中的作用:一个理论模型
摘要:在这篇论文中,作者通过构建一个理论模型来解释农民对保护性耕作技术的采用决策。保护性耕作技术具有减少土壤侵蚀、提高耕地质量、改善土壤蓄水保墒能力以及节能省工减排等多重优势,是改善我国农业生态环境、应对气候变化风险、巩固粮食生产和促进农业可持续发展的重要手段。而保护性耕作技术在我国的采用率却很低。本文的目的是探讨我国保护性耕作技术低采用率的潜在原因。这些因素包括农地规模细碎,学习能力和适应能力较低,以及抗风险能力低。通过该模型,作者讨论了备选的政策工具,如何鼓励农民采用保护性耕作技术。
