Big data is the key to building a intelligent public service mode and a technical means to promote the modernization of national governance. However, the public service mode driven by big data has problems such as inefficient government purchases and failure to achieve multi-level and cross-departmental information interaction, which directly affects the quality of public service work. This article takes the “5V” characteristics of big data as the background, discusses the “5N” feature of optimizing public services, and proposes a intelligent mode of public services driven by big data, thereby enhancing the awareness of big data at all levels of public services.

Objective: This paper was to explore whether supplementary medical insurance (SHI) can be an effective supplement to basic medical insurance (BHI). Methods: based on the data of CHARLS in 2018, the effects of BHI and SHI on residents' medical service utilization and household medical expenditure were discussed by using two-part model and quantile regression model, respectively. Results: the regression results of the two-part and quantile models showed that SHI was an effective supplement to BHI, but the effect of SHI on vulnerable groups was not favorable. Conclusion: when SHI gave full play to the efficiency of the system, it sacrificed the fairness to some extent. Government departments should continue to work to help residents improve their income and incline policies to vulnerable groups, so as to further reduce the burden of high medical expenses of residents.

With the advent of the era of big data, software and information service industries play an important role in promoting high-quality economic development, but financing constraints affect industrial development. This paper constructs a financing efficiency evaluation index system, selects the software and information technology service industry listed companies in China's GEM market from 2017 to 2019 as the research object, uses the BCC model to measure, and uses the Logit model to analyze the factors affecting financing efficiency. The results show that the overall financing efficiency of the industry has not reached the optimal state, and financing cost is the main factor restricting financing efficiency. Finally, this paper proposes suggestions from the government level and the company level in view of the low efficiency of corporate financing.

In the context of the construction of a smart society, an empirical analysis based on the macro database of the National Bureau of Statistics and the micro data of CGSS2017 found that the quality of rural labor transfer in China at this stage can no longer fully meet the needs of social development. Through big data analysis, it is found that in the process of rural labor transfer to cities in China, there are problems such as low skill level, low degree of organization, serious urban-rural division, left-behind children and empty-nest elderly. In order to improve the quality of rural labor transfer in China, so that it can adapt to the development of a better intelligent society, our government needs to take corresponding measures to improve the overall quality of rural labor, guide rural labor to transfer in a reasonable and orderly manner, unify the urban and rural labor market, and unblock family communication Channels enable rural migrant labor to have a higher competitiveness in the job market, thereby contributing to the construction of an intelligent society.

From the perspective of urban diplomacy, this paper takes the panel data of China's outward foreign direct investment in 47 “Belt and Road Initiative” countries from 2003 to 2017 as the research sample, and uses the dynamic GMM approach to examine the impact of “Sister City Relationship” on such investment. The study finds that: (1) Sister City Relationship promotes China's outward foreign direct investment in Belt and Road Initiative participating countries; (2) Sister City Relationship has diverse impact on attracting China's outward foreign direct investment in different continents and its facilitating role is more obvious in European countries; (3) Sister City Relationship can further strengthen the positive effect of overseas economic and trade cooperation zones on capacity cooperation with Belt and Road Initiative participating countries and China's outward foreign direct investment. Therefore, it is believed that Belt and Road Initiative participating countries should champion Sister City Relationship to enhance the exchanges and mutual learning between cities, set up investment promotion platforms, create new forms of cooperation and foreign investment, and accelerate opening-up in all respects.
