摘要: The rapid rise in arable land rent has affected China’s food security, and the existing literature focuses on the analysis of transferred land rents. The existing literature not only ignores the reality that more than 60% of China still owns its own cultivated land, but also ignores the analysis of cultivated land rent from the perspective of agricultural technological progress. In order to reveal the influence of agricultural technology progress on cultivated land rent and land rent rate, this paper uses the relevant data of cost and benefit of national agricultural products from 2011 to 2020, takes vegetable agricultural products as the research object, depicts agricultural technology progress with facility agriculture, and empirically analyzes the influence of agricultural technology progress on cultivated land rent and land rent rate. The benchmark regression results show that although the agricultural technology progress represented by facility agriculture significantly improves the cultivated land rent, it reduces the land rent rate. The same conclusion was also obtained with the interactive fixed effects model and the propensity score matching method and the time trend variables. The mechanism analysis results show that the agricultural technology progress represented by facility agriculture promotes the per mu output value of vegetable agricultural products more than the cultivated land rent by increasing the unit price and the per mu yield, and compared with the quantity, agricultural technology progress mainly affects the quality of vegetable agricultural products. Therefore, the need to adhere to the fundamental way out of agriculture lies in science and technology, combined with the actual agricultural development to promote the research and development, transformation and promotion of agricultural science and technology, at the same time to promote the modernization of facility agriculture, and pay attention to differentiated development.

Abstract: 耕地地租快速上涨已经影响到中国粮食安全，而现有文献对这一问题的分析聚焦于流转地租金，既忽视了中国仍然有60%以上属于自有耕地的现实，也忽视了从农业技术进步视角分析耕地地租问题。为了揭示农业技术进步对耕地地租和地租率影响，本文利用2011—2020年全国农产品成本收益等相关数据，以蔬菜农产品为研究对象，用设施农业刻画农业技术进步，实证分析农业技术进步对耕地地租和地租率的影响。基准回归结果表明，以设施农业为代表的农业技术进步虽然显著提高了耕地地租，但是降低了地租率。采用交互固定效应模型和倾向得分匹配方法，以及以时间趋势变量来刻画的广义农业技术进步也得到相同结论。机制分析结果表明，以设施农业为代表的农业技术进步对蔬菜农产品亩均产值的促进作用大于耕地地租，从而负向影响地租率；同时也会通过提高单位价格和亩均产量来提高耕地地租，且相对于数量，农业技术进步主要作用于蔬菜农产品质量。由此，需要坚持农业的根本出路在于科技，结合农业发展实际推动农业科技研发、转化与推广，同时促进设施农业现代化发展，注重差异化发展。

• 说明： 与现有研究相比，本文的边际贡献体现在以下三个方面：一是，本文以设施蔬菜农产品为例，从农业技术进步的视角讨论了耕地地租和地租率的影响因素，并通过实证分析发现以设施农业为代表的农业技术经济进步提高了耕地地租，同时降低了地租率，丰富了耕地地租和地租率的研究视角；二是，本文考虑了中国仍然有60%以上属于自有耕地的现实，明确将被解释变量聚焦于耕地地租而非流转地租金，并在实证分析过程中，考察了农业技术进步对流转地租金和自营地折租的影响，丰富了耕地地租的研究内容；三是，本文通过交互固定效应和倾向得分匹配方法讨论了模型的遗漏变量问题和样本选择偏差问题，更为充分地考虑了模型的内生性问题，从而得出的研究结论更为稳健，也更为准确。
