摘要:

中国农业面临着劳动力老龄化与绿色化转型的双重约束。聚焦于跨期技术属性,本文提出了中国情景下年龄对农民跨期绿色农业技术采纳的倒U形影响假说,进而以秸秆还田为例,采用中介效应模型,利用冀鲁皖鄂4省1372份农民调查数据进行了实证检验。结果发现:①年龄对于农民跨期绿色农业技术采纳的影响效应呈倒U形态势,“中年农民”成为现阶段绿色农业技术扩散的积极力量;②人力资本和风险偏好是年龄影响农民跨期绿色农业技术采纳的重要中介变量,两者的中介效应占年龄总效应的71.94%;③信息化和耕地规模对中青年农民的跨期绿色农业技术采纳具有促进作用;经济价值认知、是否贫困、供水情况、补贴和处罚政策对中老年农民采用跨期绿色农业技术表现出积极影响;社会资本对中青年农民的技术采纳具有负向影响,但有利于中老年农民采纳跨期绿色农业技术。由于年龄较高农民积极采纳跨期绿色农业技术其实是该群体非农就业机会减少而被动“以农为业”的结果,这表明农业生产包括农业资源保护与开发缺乏最为优质的劳动力支撑;另一方面,非农就业的青壮年劳动力由于缺乏务农经历,多年后回归农业又能否承担起农业绿色化转型的责任也值得思考。因此,劳动力老龄化对中国农业短期的影响在于如何把地种好,而长期的潜在威胁依然是谁来种地。

Abstract:

Based on the intertemporal technical attributes, this study systematically explored the influence of age on farmers’ adoption of intertemporal green agricultural technology, and conducted an empirical test by employing the survey data of 1,372 farmers in Hebei, Shandong, Anhui, and Hubei Provinces and using a mediating effect model. The results show that, first, the effect of age on farmers’ adoption of intertemporal green agricultural technology is inverted U-shaped. Second, human capital and risk preference are two important mediating variables for the influence of age, whose mediating effects explain 71.94% of the effect of age. Third, information and scale of land parcels play an important role in promoting the younger farmers’ adoption of intertemporal green agricultural technology, while economic value cognition, poverty, water supply, subsidies, and punishment policies have a positive impact on the adoption of intertemporal green agricultural technology by older farmers. Social capital has a negative impact on the adoption of green technology of young farmers, but it is beneficial for old farmers to take action. In the long run, speeding up the cultivation of new professional farmers, improving the new agricultural management system, and further developing the agricultural insurance system are important ways and necessary guarantee for the adoption of intertemporal green agricultural technology.
