尽管之前的研究已经表明土地保有权保障 (LTS) 意识对农业投资的重要性，但迄今为止，关于土地保有权保障意识影响的定量证据还很少。本研究显示了 LTS 意识对农业投资的因果影响，为当前的研究做出了贡献。具体来说，我们研究了对延长农业土地使用权期限的认识是否会提高农民对农业的投资。根据越南2013年11月通过的新土地法，每年耕地和水产养殖用地的使用期限从20年大幅增加到50年，这使越南成为检验这一假设的一个令人信服的案例研究。我们使用 2010 年、2012 年、2014 年和 2016 年收集的越南资源获取家庭调查 (VARHS) 面板数据。平衡面板数据包括 1834 个家庭。采用固定效应双重差分 (DID-FE) 来估计因果影响。我们发现，对延长农业土地使用权期限的认识增加了对灌溉/水土保持/节水和有机肥料采用的投资，这支持了对长期服务的认识对可持续投资的积极影响。
Although previous studies have shown the importance to agricultural investments of awareness about land tenure security (LTS), to date, little quantitative evidence has been published regarding the effects of awareness about LTS. This study contributes to the current research by showing the causal effect on agricultural investments of awareness about LTS. In detail, we examine whether awareness about the increase in the duration of agricultural land-use rights improves farmers’ investments in agriculture. Under the new land law passed in November 2013 in Vietnam, the usage duration of annual cropland and aquaculture land increased significantly from 20 years to 50 years, which makes Vietnam a compelling case study for testing this hypothesis. We use panel data from the Vietnam Access to Resources Household Survey (VARHS) collected in 2010, 2012, 2014 and 2016. The balanced panel data include 1834 households. Difference-in-difference with fixed effects (DID-FE) is employed to estimate the causal impacts. We find that awareness about the increase in the duration of agricultural land-use rights increases investments in irrigation/soil conservation/water conservation and the adoption of organic fertilizer, which supports the positive impacts of awareness about LTS on sustainable investments.
