高地租必然不利于农户保护耕地质量吗?——基于广西的问卷调查

Is high land rent not conducive to protecting the quality of farmland? Based on a survey of farmers in Guangxi

Key words:  high land rent  cultivated land quality protection behavior  soil testing formula  returning straw to the field

摘要:

以广西壮族自治区农户调查为例，验证土地成本对农户耕地质量保护行为有何影响。基于Binary Probit和Biprobit模型，研究发现:土地租金越高时，农户反而更可能采纳测土配方与秸秆还田这两类耕地质量保护行为。分样本回归发现，相对规模较小的农户，土地成本会促使经营规模较大农户更积极的采纳测土配方和秸秆还田两类绿色技术类保护措施。进一步的研究表明，农户之所以更倾向于施测土配方肥，是因为这类保护性措施能显著降低农业生产成本和有效提升农业经营性收入，更倾向于采纳秸秆还田技术则是因为这类耕地质量保护行为能够显著提升农业经营性收入。说明高地租并不必然导致农户消耗地利，面对地租成本压力，采纳绿色技术类耕地质量保护措施也是农户的可能选择之一。

Abstract:

In order to verify how the land cost affects farmers' cultivated land quality protection behavior, this study conducts an empirical test based on a survey of farmers in Guangxi. The result show that when the land rent is higher, farmers are more likely to adopt two types of cultivated land quality protection behaviors, such as soil testing formula and straw return to the field. The sub-sample regression finds that, campared to smaller scale farm farmers, high land rents can prompt large scale farm farmers to be more actively to adopt the two types of green technologies. Further study discovers that: The reason why farmers are more inclined to apply soil formula fertilizers is that such protective measures can significantly reduce agricultural production costs and effectively increase agricultural income, and the protection of cultivated land quality can significantly increase agricultural business income. In conclusion, the high land rent does not necessarily lead to the consumption of land by farmers, but it will prompt farmers to adopt more green technology-type protective measures for farmland quality protection.
