粮食贫困脆弱性是指个人在不久的将来降至粮食贫困线以下的可能性，它提供了一种前瞻性的福利分析。本研究采用全国代表性的调查数据，探讨了新农村养老金计划（NRPS）在减少农村慢性病老年人食物贫困和脆弱性方面的作用。通过设计各省的食物贫困线，以考虑到老年人需求的差异，以及使用最低成本线性规划方法的各省价格，计算出患有慢性病的老年人的食物贫困发生率。应用三阶段可行广义最小二乘（FGLS）程序，估计粮食贫困的脆弱性。结果表明，中国农村慢性病老年人食物贫困发生率和脆弱性分别为41.9%和35%，比健康老年人分别高出8个百分点和6个百分点。为了解决养老金支付的潜在内生性问题，采用模糊回归不连续（RD）回归研究了养老金收入对不同人口群体食物贫困和脆弱性的影响。研究发现，养老金收入降低了12.9%和16.8%的慢性病老年人的食物贫困的概率和食物贫困的脆弱性，而对健康的老年人没有显着的影响。
Vulnerability to food poverty is the probability of an individual falling below the food poverty line in the near future, which provides a forward-looking welfare analysis. Applying a nationally representative survey dataset, this study investigates the role of the New Rural Pension Scheme (NRPS) in reducing food poverty and vulnerability among the rural elderly with chronic diseases. By designing province-specific food poverty lines to account for variations in the elderly’s needs, as well as the prices across provinces using a least-cost linear programming approach, the food poverty incidences among the elderly with chronic diseases are calculated. Applying a three-stage feasible generalized least squares (FGLS) procedure, the vulnerability to food poverty is estimated. Our results show that food poverty incidence and vulnerability of the elderly with chronic diseases in rural China is 41.9% and 35% respectively, which is 8% and 6% higher, respectively, than the elderly that are in good health. To address the potential endogeneity of pension payment, a fuzzy regression discontinuity (RD) regression is employed to investigate the effects of pension income on food poverty and vulnerability for different population groups. We found that pension income decreases the probability of being food poor and the vulnerability to food poverty among the elderly with chronic diseases by 12.9% and 16.8% respectively, while it has no significant effect on the elderly in good health.
