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.
