复合经营技术、劳动供给与农户增收

为考察经济林复合经营技术采用对农户家庭收入的影响及作用机制，明晰经济林复合经营技术增收效益的约束条件，本研究利用浙闽赣3省568户农户抽样调查数据，用计量模型进行实证分析。研究表明：经济林复合经营技术采用能显著增加农业收入，原因在于增加了农户农业劳动时间，尤其是对低禀赋农户的作用更明显。通过反事实估计发现，复合经营技术的增收效应在不同技术采用状态的农户家庭中均存在。对于已采用技术的农户，经济林复合经营技术的增收效应仅在高禀赋农户中产生。对于未采用技术的农户，经济林复合经营技术的增收效应在所有农户中均存在。本研究为理解经济林复合经营技术影响农户收入的作用机制提供了新的经验证据，也为进一步促进技术扩散提供了参考。

Compound management technology, labor supply and household income

In order to analyze the influence and mechanism of economic forestry compound management technology adoption on farm household income, and to clarify the constraints on the income-increasing benefits of economic forestry compound management technology, this study applies an econometric model to do empirical analysis of data from a sample of 568 farm households, collected in Zhejiang, Fujian and Jiangxi provinces. The results show that: The adoption of economic forestry compound management technology can significantly increase the agricultural income of farm households, especially significant for low-endowment farmers, and is achieved by increasing agricultural labor time for farmers. The counterfactual estimation reveals that the income-increasing effect of compound management technology is present in farm households with different technology adoption statuses. For farmers who have adopted the technology, the income-increasing effect of economic forestry compound management technology occurs only among high-endowment farmers. For farmers who have not adopted the technology, the income-increasing effect of the economic forestry compound management technology occurs in all endowed farmers. This study provides new empirical evidence for understanding the mechanism of the impact of compound management technology on farmers'' income, and also provides reference for further technology promotion.
