利用埃塞俄比亚提格雷地区改革前后长达八年的面板数据，评估低成本土地确权对土壤保护、树木投资和土地生产率的积极影响，并处理了内生性问题。
Abstract New land reforms are again high on the policy agenda and low‐cost, propoor reforms are being tested in poor countries. This article assesses the investment and productivity impacts of the recent low‐cost land certification implemented in the Tigray region of Ethiopia, using a unique household and farm‐plot‐level panel data set, with data from before and up to eight years after the reform. Alternative econometric methods were used to test and control for endogeneity of certification and for unobserved household heterogeneity. Significant positive impacts were found, including effects on the maintenance of soil conservation structures, investment in trees, and land productivity.
