At present, China has become one of the fastest growing countries in terms of junk food consumption. However, there has been less previous evidence for the effect of endowment insurance on dietary health. Using the data China Family Panel Studies (CFPS) from 2014, this paper exploits a policy, the New Rural Pension System (NRPS), that only the older adults who have reached 60 years old can receive pensions and conduct a fuzzy regression discontinuity (FRD) to address endogeneity and examine the causal effect of the NRPS on the intake of junk food among rural older adults in China. We find that the NRPS can significantly reduce junk food intake among them, which remains robust after a series of robustness tests. In addition, heterogeneity analysis shows that the female, low-educated, unemployed, and low-income groups are more sensitive to the pension shock from the NRPS. The result of our study provides insights to effectively improve people's dietary quality and related policy formulation.
目前，中国已成为垃圾食品消费增长最快的国家之一。然而，此前关于养老保险对饮食健康影响的证据较少。本文利用中国家庭追踪调查（CFPS）2014 年的数据，利用一项仅允许年满 60 岁的老年人领取养老金的政策——新型农村社会养老保险（NRPS），采用模糊回归不连续设计（FRD）来解决内生性问题，并考察 NRPS 对中国农村老年人食用垃圾食品的因果效应。结果发现，NRPS 可以显著降低农村老年人食用垃圾食品的比例，这一结果在一系列稳健性检验后仍然成立。此外，异质性分析表明，女性、受教育程度低、失业和低收入群体对 NRPS 的养老金冲击更为敏感。本研究结果为有效提高人们的饮食质量和相关政策制定提供了启示。
