摘要:

【目的】 分析退耕还林农户在采用果树新品种时的行为决策逻辑,为引导退耕经果林换种,促进后续产业持续发展以及巩固退耕还林成果提供参考。【方法】 基于退耕农户技术禀赋对采用经果林新品种行为决策影响机理的理论分析,利用川渝397份退耕柑橘种植户微观调查数据,运用IVProbit模型、IVTobit模型实证分析不同技术禀赋的退耕农户在换种行为方面的差异及原因。【结果】 退耕农户的经果林管理技术水平普遍不高,且农户之间存在显著的差异。种植管理技术水平对退耕农户换种与否有正向影响,技术水平越高,换种可能性越大;种植管理技术水平对退耕农户换种时期、换种强度的正向影响更为显著,技术水平高的农户,在采用新品种方面表现出很强的“追新”特征。【结论】 通过实施相应的举措提升退耕农户整体技术水平,对于推动果树品种更新换代,促进退耕还林后续产业持续健康发展具有重要意义。

Abstract:

【Objective】 The purpose of this study is to analyze the complementation with management technology characteristics of adopting new fruit tree varieties and reveal the decision-making logic of farmers in adopting new fruit tree varieties. We aim to provide a reference for guiding the adoption of fruit tree varieties, promoting the sustainable development of follow-up industries and consolidating the achievements of conversion from farmland to forest.【Method】 Based on the theoretical analysis of the influence mechanism of farmers’ technical endowments on the decision-making behavior of adopting new varieties, using micro survey data of 397 farmers in Sichuan and Chongqing, China, we analyzed differences among and reasons for farmers with different technical endowments’ adoption behavior of new varieties through the IVProbit and IVTobit models.【Result】 The level of economic fruit forest management technology of farmers returning farmland to forest is generally not high, and there are significant differences among farmers. The level of management technology has a positive impact on the adoption of new varieties. Farmers with higher levels of management technology are more likely to adopt new varieties. The level of management technology has a positive impact on the period and the intensity of adopting new varieties. Farmers with a higher level of management technology are characterized by “catching up with the new” in adopting varieties. 【Conclusion】 Effective measures to improve the management technology of farmers who have returned farmland to forest are conducive to the renewal of varieties and the healthy development of the follow-up industry.
