较弱的需求反应一直是保护性耕作技术采用率低下的直接原因。将组织支持和跨期选择引入农户保护性耕作技术采用问题的研究，既是对传统技术采用理论研究范式的拓展，也是构建保护性耕作技术采用长效激励机制的关键。本项目运用农户调查资料、典型案例和实验数据，在对保护性耕作的技术属性及组织支持特征进行解析的基础上，探究组织支持、跨期选择对保护性耕作技术采用的需求诱导机制、路径和效应。拟采用久期模型（DA）、门槛回归模型（TR）、MESR等计量经济模型分析农户保护性耕作技术采用的潜在需求、实际需求和持续性需求；应用KHB模型探究组织支持诱导农户保护性耕作技术采用的具体路径；运用结构方程模型（SEM）分析组织支持和补偿政策对农户保护性耕作技术采用的交互影响。最后，提出促进组织支持，提高保护性耕作技术采用的制度创新思路和政策主张。

The main reason for low adoption rate of conservation tillage technology is farmers weak demand response. Our study incorporates the concept of organizational support and inter-temporal selection into the conservation tillage technology adoption framework. It is not only an extension of the traditional theoretical paradigm for technology adoption, but also the key to construct a long-term incentive mechanism for adopting conservation tillage technology. Firstly, this project elaborates the characteristics of conservation tillage technology and organizational support. Then, it recruits rural household survey data, case study and experimental data to explore the mechanisms and effects of organizational support and inter-temporal selection on farmers’ conservation tillage technology adoption. DA model, threshold Regression model (TR), MESR model and other econometric models are employed to analyze farmers potential demand, the actual demand and the farmers' sustainable demands for tillage conservation technology; KHB model is applied to explore the specific path adopted by the organization to support farmers' conservation tillage technology; Structural Equation Modeling (SEM) is used to analyze the interaction effects of organizational support and compensation policies for farmers' conservation tillage technology adoption. Finally, we put forward to innovative mechanisms and policy implication for promoting organizational support and improving farmers’ conservation tillage technology adoption.
