摘要简单翻译：
对稀缺和零散土地的低效利用对农业的可持续性提出了挑战。土地市场可能提高土地利用效率。近年来，中国采用各种手段推动土地市场。本文根据江苏省1,202户农户的数据，调查土地市场是否影响家庭的土地利用效率。土地利用效率的测量来自随机前沿生产函数，并且采用控制函数方法来校正选择偏差。结果表明，许多家庭使用土地的效率低下。 虽然在土地上租房可以提高土地使用效率，但不会受到出租土地的影响，这意味着家庭不会放弃土地以提高效率。我们还提供了有力的证据，表明由于劳动力市场的失败，土地租赁的积极影响是由丰富的农业劳动力造成的。
ABSTRACT
Inefficient use of scarce and fragmented land challenges the sustainability of agriculture. Land markets may improve land-use efficiency. In recent years, China has employed various instruments to promote land markets. This paper investigates whether land markets affect households’ land-use efficiency, based on data from 1,202 farm households in Jiangsu Province. The measure of land-use efficiency was derived from a stochastic frontier production function, and a control function approach was employed to correct for selection bias. The results indicated that many households are using land inefficiently. While renting in land increases land-use efficiency, it is not affected by renting out land, implying that households are not giving up land for efficiency gains. We also provide suggestive evidence that the positive effect of renting in land results from abundant agricultural labour due to labour market failure.
