“…This is mainly due to the agricultural policy, pandemic prevention measures and supply chain upgrading strategy promoted by the Chinese government in recent years, which have increased the resilience of food supply chain (specifically in the adaptation aspect). The results support the findings of Jiang et al (2021) and Consoli et al (2023). Meanwhile, government decision-makers should also be alert to major health events such as COVID-19 which breaks the food supply chain by depressing consumption prices and enterprise profits for a long time.…”

“…However, when a serious outbreak of zoonotic infectious diseases causes reduction of raw material supply, labor shortage, production cost increase, and fluctuations in food production, the prices of raw materials and food rise rapidly. The results verify the findings of Saboori et al (2022) and Consoli et al (2023). Therefore, when serious infectious diseases break out, government decision-makers should be vigilant and prevent the sharp rise of agricultural products and food prices in the short term.…”

IntroductionThe fragility of agriculture makes the food supply chain vulnerable to external risks such as epidemic, conflict, disaster, climate change, economic and energy crisis. The COVID-19 pandemic has spread and continued globally in recent years, resulting in food supply chain disruption and insecurity, which triggers profound reflection on the impacts of public health events (PHEs). Studying the impacts of PHEs on the resilience of food supply chain has great significance to effectively reduce the risks of disruption and insecurity in the future.MethodsBased on the composition of PHEs and the division of food supply chain, this paper adopted the nonlinear Granger causality test to verify the nonlinear causal relationship between PHEs and proxy variables in the food supply chain; then the TVP-VAR-SV model was constructed and its three-dimensional pulse response results were matched with the sensitivity, recovery, and adaptation of the food supply chain resilience to deeply explore the dynamic impacts of PHEs.ResultsPHEs has significant nonlinear conduction effects on the resilience of food supply chain, the impacts of PHEs on the partial sector resilience have significant dynamic characteristics in the whole sample period, and the impacts of PHEs on the recovery and adaptation aspects of food supply chain resilience have structural break characteristics.DiscussionThe differences, dynamic characteristics and structural breaks of the impacts of PHEs on the resilience of food supply chain are caused by the infectivity and mortality of PHEs, attributes of food products, regulation of supply and demand in the market, behavioral decisions of all participants, changes in the policy environment, and coordination and upgrading of all sectors in the supply chain.

“…While some existing studies have illustrated the relationship between food security policy and food price from the perspective of food policy reform [ 29 ], they have not analyzed this relationship in the context of responding to public health emergencies. Other studies have developed indicators, such as the monthly nominal rate of protection, an “express” indicator to reflect the real-time impact of food security emergency policy on grain prices [ 30 , 31 , 32 ], but have not considered the influence of food types and regional heterogeneity. This study differs from previous research in that it uses two indicators, the food price volatility index ( CV ) and food price increase rate ( ROC ), to quantitatively and visually analyze the relationship between China’s food security emergency policy and four kinds of food prices, in order to clarify the impact of food security emergency policy on food prices.…”

Achieving the goal of zero hunger within the goal of sustainable development requires improving the resilience of food systems to various types of risk shocks; food systems have shown significant vulnerability to COVID-19 outbreaks and transmission. By analyzing the impact of China’s lockdown policy and food security emergency policy in 2020 on food prices during the COVID-19 pandemic, we can clarify the role of policy intervention in enhancing the resilience of the food system, which can provide guidance, using China’s experience, for dealing with global food safety emergencies in the future. Firstly, we selected Beijing, Shanghai and Guangdong as food-consuming areas, and Shandong, Henan, and Hubei as food-producing areas. We also collected food security emergency policy data from the Chinese government website during the COVID-19 pandemic. Secondly, a difference-in-difference method was used to observe that Chinese cabbage and pork prices in the main food-producing areas and food-consuming areas rose more obviously after the adoption of lockdown policy, and Chinese cabbage and pork prices in the food-consuming areas increased more obviously than those in food-producing areas. However, staple food prices have not risen significantly. Thirdly, the response of four kinds of food prices to the food security emergency policy is analyzed quantitatively and graphically using the food price volatility index and food price increase rate; we observed that the response of food prices to the food security emergency policy is related to the food types and regions. For food types, the fluctuation degree and increase in Chinese cabbage and pork prices decreased significantly after the adoption of the food security emergency policy. For regions, when the food security emergency policy was adopted, the food prices in the main food-consuming areas fluctuated more obviously than those in food-producing areas. Finally, we found that the implementation of the transport policy and the joint supply emergency policy in the main producing and consuming areas has played a very significant and positive role in stabilizing food prices.

“…This paper focuses mainly on answering the previous discussion in academia; that is, since the COVID-19 epidemic has caused severe damage to residents’ mental health, will residents’ mental health improve after relaxing the control policy of the COVID-19 epidemic? Meanwhile, we discuss the possible mechanism or reason from the perspective of family tourism consumption, unlike many previous studies that only studied the influence of COVID-19 on one aspect, such as the enterprise supply chain, food import and export, household production decisions, and the mental health of residents ( 10 , 93 , 94 ). However, the current study explores the link between RCC, family tourism consumption, and the mental health of residents, which could provide a more plausible explanation for the knock-on effects of COVID-19.…”

ObjectiveCOVID-19 has negatively influenced industrial development, family consumption, and residents’ mental health. Unfortunately, it has not yet been studied whether this adverse situation can be alleviated after the relaxation of the COVID-19 control policy (RCC). Therefore, this study aimed to analyze the effect of the RCC on the resident’s mental health and the mediating effect of family tourism consumption.Methods By using the PSM and mediating effetc model to research the panel data of two periods (April 2021 and April 2023) for Shaanxi province, China.ResultsThe RCC negatively inhibited the mental health severity of residents, and the mental health severity decreased by 0.602. In particular, the RCC showed the most substantial negative effect on residents’ stress, followed by anxiety and depression. Meanwhile, it is found that the impact of the RCC on the mental health of residents is highly heterogeneous. The RCC indicates a linear significant effect on the mental health of residents under 60 years of age, while the results were found insignificant for residents above 60 years of age. Meanwhile, the RCC’s improvement effect on urban residents’ mental health is greater than that of rural residents. In addition, mechanism analysis showed that tourism consumption plays a mediating role in the influence of the RCC on the mental health of residents, and the mediating effect accounted for 24.58% of the total effect.ConclusionBased on the findings, the study proposes that government and policymakers should strengthen mental health intervention, improve access to mental health counseling, stimulate economic development, expand the employment of residents, and track the mutation of the novel coronavirus.
