HOW TENURE SECURITY AND FARMLAND TRANSFER AFFECTED FARMLAND INVESTMENT: EVIDENCE FROM APPLE GROWERS IN CHINA
利用中国苹果种植户数据，分析土地权属保障和农地流转对农地投资的影响，发现租入地（未约定租期）的农家肥投入显著减少，而地租和流转面积增加会促进投入。
Tenure insecurity and thin land rental markets weakened the incentives to farmland investment in rural China, which was not conducive to improving agricultural productivity. Thus, impacts of tenure security and farmland transfer on farmland investment were analyzed by using the household fixed effect model, the IV method and a 762 household-level and 1163 plot-level data set. The results indicated that: (1) compared with owned plots, the number of farmyard manure in rented plots without stipulating rental time was significantly decreased by 64.0~66.9%; (2) each 1% increase in land rents led to a 1.7% rise in the input of farmyard manure; (3) each 1% increase in the size of farmland transfer resulted in a 0.1% rise in the input of farmyard manure. Our study contributed to boosting agricultural sustainable development from the perspectives of improving the systems of farmland property rights and developing farmland rental markets.
