Food safety is of vital interest for public health and the stability of society. In this paper, we analyzed the characteristics of food safety incidents (FSIs), including spatial distribution, food categories, risk factors, and supply chain links, reported by mainstream media in China. Based on our analysis, we constructed a semantic template for text data related to FSIs. Furthermore, we introduced a multi-layer, multi-level semantic structure of rank (MMSS-Rank) algorithm to measure the similarity between collected food safety data and the semantic template. We then calculated the overall scores (i.e., text layer weight, semantic template weight, and keyword density matrix) and selected an appropriate threshold to determine the accuracy of the FSI data. Results showed that, compared with traditional methods, MMSS-Rank is an efficient and robust method for identifying large-scale FSI data with higher accuracy and recall rate.

There is a natural relation between human health and the quality of their food and drinks, and elevating the quality input level of food production for all enterprises within the food supply chain system forms the foundation for preventing various potential food safety risks that may be encountered. Unlike the previous research on quality investment of food production by enterprises, this paper probes into the evolutionary routes of the behavior strategy selection of subjects in the food supply chain and the preconditions for the equilibrium points of the social co-governance system. It takes the approach of establishing a tripartite evolutionary game model of food suppliers, food manufacturers and consumers on the basis of the social co-governance framework, in view of the above, this paper focuses on the influence of the reputation mechanism and the market contracts among supply chain subjects on the selection of a behavior strategy for quality investment by enterprises under the condition of lawful regulation by government. The results show that every subject selects their own behavior strategy on the basis of the balance of their respective interests. The net disbursement incurred by enterprises for quality investment and the costs of participation in governance by consumers constitute the dominant factors that influence both enterprises’ selection of a behavior strategy and the level of social co-governance. Compared with the increase in economic punishment imposed on suppliers for production of risky food raw materials, it is more efficient to control food safety risks by lowering the costs of quality investment by suppliers. Accordingly, this paper proposes advice on policy in an attempt to provide inspiration for preventing and controlling food safety risks.

This paper unravels the new multi-relational rescaling of state-level new areas (SNAs) in China’s up-to-date city-region-building. These nationwide SNAs have created an unimpeded governance pathway among multi-level governments and multi-scalar localities. As proofed by our empirical study on the establishment history of Jiangbei SNA, this new pathway has consolidated the re-centralization, reconfiguration, and re-marketization tools that can be adopted as comprehensive governance approaches by the state to resolve the long-term dilemma in city-regional governance since the incremental development in the 1990s characterized by frequent failure on administrative intervention, ungrounded regional strategies, and disordered inter-city competitions. Furthermore, the successful practice at Jiangbei SNA can function as a positive reference for developing China’s city-regions towards a region-in-becoming so that national initiatives in city-region-building can be dynamically adjusted accordingly.
