中文摘要:
      耕地保护性投资不足导致土地资源退化和农业经营效率低下一直是困扰发展中国家的重点难题之一。基于预期理论和“公地悲剧”理论,利用8个省份微观调查数据,采用Tobit模型和Probit模型进行基准回归分析,并通过CMP模型纠正可能存在内生性偏误,分析不同产权认知情况下农户的有机肥施用和工程措施两类耕地保护性投资行为差异,探讨土地所有权认知对农户耕地保护性投资行为的影响。结果表明,被调查农户的耕地保护性投资现状并不理想,平均有机肥施用量只有1.442 t/hm2;2009—2012年仅有12.1%的地块进行过平整土地、修建梯田、开垄沟、修建水渠等工程措施类耕地保护性投资。农户对土地所有权的认知可分为强产权认知和弱产权认知,强产权认知的农户有机肥施用量显著高于弱产权认知的农户,强产权认知农户比弱产权认知农户平均多施有机肥1.137 t/hm2。土地所有权认知对工程措施类耕地保护性投资具有显著且稳健的影响,强产权认知农户比弱产权认知农户采纳工程措施的概率高4.9%。因此,在“制度先行,认知滞后”的背景下,应当进一步明晰产权、加强农户的土地所有权认知以促进农户耕地保护性投资行为。
英文摘要:
      Insufficient protective investment in farmland (PIF) leads to degraded land resources and inefficient agricultural operations, which have always been one of the main problems that plague developing countries. Most researches have focused on the impact of objective arrangements of property rights on farmers’ PIF, and lack of discussion on farmers’ cognition of property rights. Based on a data of 8 provinces, and applying the Expectation theory and the “Tragedy of the Commons” theory, this paper examined the influences of the cognition of land ownership (CLO) on farmer’s PIF by the Tobit model and the Probit model. Results show that: The PIF of the investigated farmers is not satisfactory that they use only 1.442 tons manure per hectare and only 12.1% of the plots were taken engineering measures, including leveling land, constructing terraced land, and building irrigation systems from 2009 to 2012. farmers’ CLO can be divided into strong CLO and weak CLO. Firstly, the CLO has a significant positive impact on the application amount of manure. On average, farmers with strong CLO applied 1.137 tons more manure per hectare than that of farmers with weak CLO. Secondly, the CLO has a significant and robust impact on engineering measures. Strong CLO promotes engineering measures. Farmers with strong CLO have 4.9% higher probability of conducting this series of PIF than that of farmers with weak CLO. Therefore, under the background of “system first, cognition lag”, further clarification of property rights and strengthening farmers’ CLO are of great significance to promoting farmers’ PIF.
