Background Falls among older adults will cause a heavy burden on society and families. The development of effective falls prevention intervention policies for community-dwelling older adults is an important initiative to address this global public health problem. Objective To analyze and compare the content composition, key initiatives and implementation strategies of current falls prevention intervention policies for community-dwelling older adults in different countries from the perspective of policy tools. Methods Six countries in Asia, North America, and Europe, including Japan, Singapore, Thailand, the United States, Germany, and Russia, were selected as sample countries according to the degree of population aging and economic income level. Refer to the websites of relevant government departments such as the Ministry of Health, the Center for Disease Control and Prevention and directly affiliated institutions, as well as websites of nongovernmental organizations, such as Prevention of Falls Network Europe, National Council On Aging, U.S., Association of Fall Prevention, Japan, and National Association of Statutory Health Insurance Funds, Germany, the national policy documents of prevention interventions for community-dwelling older adults from January 2010 to June 2022 were searched by using "older adults" "fall/drop/accidental injuries" "prevention" as keywords. The text analysis was performed from the dimensions of policy tools such as demand-side type, supply-side type and environmental-side type, and injury prevention strategies such as education prevention strategies and evaluation strategies. Results Among the 24 policy documents, there were 212 coded targets in the dimension of policy tools, with environmental-side type, supply-side type and demand-side type policy tools accounting for 45.3% (96/212), 40.6% (86/212) and 14.1% (30/212), respectively. Among high-income countries, the public service tools under supply-side type policy tools were mostly applied in the United States and Germany, accounting for 40.5% (17/42) and 13.8% (8/58) ; the infrastructure construction tools under supply-side type policy tools were focused in Singapore〔24.1% (7/29) 〕. Among low and middle income countries, the environmental-side type policy tools were mostly applied in Russia and Thailand, accounting for 51.3% (20/39) and 55.6% (10/18), respectively. Public service was mostly applied among the supply-side type policy tools, accounting for 17.5% (37/212) ; technical standard was mostly applied among the environmental-side type policy tools, accounting for 10.8% (23/212) ; medicare payment was mostly applied among the demand-side type policy tools, accounting for 4.7% (10/212). In addition, there were 105 coded targets in the dimension of injury prevention strategies, with the education prevention strategies accounting for the highest proportion of 31.4% (33/105), the engineering strategy accounting for the lowest proportion of 5.7% (6/105). High-income countries are at the stage of multi-sectoral collaborative policy implementation, low and middle income countries are at the stage of policy implementation by the Ministry of Health stage. Conclusion Six countries focus on public service and infrastructure development under supply-side type policy tools; the application of demand-side type policy tools can be summarized as intervention services managed by medical insurance, intervention projects supported by financial funds, service purchases attracted by price subsidies, planning, organization, advocacy, and standard setting of environmental-side type policy tools. In combination with the priorities and specific measures of the six countries, it is suggested to learn from advanced experience in improving public services, strengthening evidence-based projects, standardizing technical standards, supporting financial incentives, expanding medical insurance programs, and providing price subsidies, thus further optimizing falls prevention intervention policies for community-dwelling older adults.

Industrial policy plays an extremely important guiding role in industrial growth and development. Since the 1980s and 1990s, the rapid development of high technology has promoted the organic integration of culture and economy, giving birth to a new format of cultural and creative industry. Countries all over the world have formulated corresponding industrial policies to promote the development of cultural and creative industry. Cultural and creative industry policy with the important functions of remedying market defects, optimizing resource allocation and protecting industrial development has become the hotspot of related research in the theoretical circles. In view of few results of econometric analysis on cultural and creative industry policies, in order to strengthen the guiding role of cultural and creative industry policy on industrial development, it is necessary to summarize and analyze the results of existing cultural and creative industry policy research. Adopting the method of bibliometrics and taking 411 cultural and creative industry policy research documents retrieved from CNKI as samples, this paper conducts clustering and econometric analysis on the cultural and creative industry policy research documents from the dimensions of annual document distribution, core author distribution, research institution distribution and research frontier using CiteSpace and Excel software, and draws the corresponding knowledge map to explore the theme evolution, focus of attention and research trend of cultural and creative industry policy research. All the sample data in this paper come from CNKI, which is a relatively complete and authoritative journal database in nowadays China, so as to ensure the authority of the research samples and the high quality of the research conclusions. The econometric analysis of cultural and creative industry policy research literature can not only provide decision-making reference for the policy-making of cultural and creative industry, but also provide theoretical guidance for the differentiated development and the construction of new pattern of regional cultural and creative industry. It is found that the research on China’ s cultural and creative industry policy started at the beginning of the new century, reached a climax around 2013, and showed a downward trend after 2015; China’s cultural and creative industry policy research forces are unevenly distributed in a relatively scattered state, and no cooperation network among research institutions has been established; China’ s cultural and creative industry policy research has gradually shifted from focusing on industrial development in the initial stage to focusing on system reform and policy entity content. The current research pays increasing attention to the combination with the practice of socio-economic development. The existing cultural and creative industry policy research mainly focuses on theoretical discussion, and lacks quantitative analysis of different industrial categories and different local policies, which is not conducive to improving the accuracy and pertinence of policy formulation. In the future, we must strengthen the integration of research forces, establish a cooperative research network, promote the cooperation and exchange among research institutions, and strengthen the quantitative research on the cultural and creative industry policies. In view of the important role of cultural and creative industry in promoting regional economic development, cultural and creative industry policy research is still a major issue to be continued. The expansion and refinement of the content and scope of cultural and creative industry policies, the construction of cultural and creative industry policy coordination mechanism, the optimization and governance of cultural and creative industry policy network structure, the evaluation of cultural and creative industry policy effectiveness and policy effect analysis will be major topics worthy of in-depth study in the future.

Food is highly related to the national security and people’s livelihood. The efficient supply of food depends on the efficient operation of the whole food system. At present, domestic research on food system is rare, therefore, systematically sorting out the research progress abroad can provide a good reference for China’s food system research. In order to better grasp the research context of the food system, this paper studies foreign food system research literature by document analysis. Relevant theories, methods and main research fields of food system research are summarized and analyzed. Food system is the organic integration of economic, social, and ecological sustainable development consisting of the interaction of subsystems such as production, processing, distribution, consumption, and waste disposal based on the elements of material, capital, technology, culture, and political system. Food Footprint, GIS Analysis, Food Domain Analysis, Stakeholder Analysis, Life Cycle Theory, Elasticity Theory, Food Landscape and Scenario Analysis are the most commonly used methods in food system study. Focusing on the research content, globalization and localization of food systems, food system planning, resources and environmental effects on the food system, food safety and policy research are systematically reviewed. Based on the study of food system research abroad and existing research foundations and social needs in China, the focuses of China’s food system research are proposed, including empirical studies on food systems at different scales, interdisciplinary and multidisciplinary research, the design of quantitative index systems for food systems, the impact of technological innovation on food systems, and research on stakeholders in food systems, etc. [ABSTRACT FROM AUTHOR]
