 More than 100 thousand posts about “Chinese culture” on twitter were captured and the information of their publishers and people who like or collect the posts were obtained The users’ regions were divided into 39 information blocks according to geographical locations, leaving a 39×39 matrix with transmitter-receiver relationship to locate users’ position in global communication based on their situation in different information blocks by means of SNA (social network analysis) Meanwhile, LDA（latent dirichlet allocation）model was used to observe the probability distribution of 100 thousand posts on 50 topics, from which we can understand the similarity of “Chinese culture” description from different blocks by calculating the cosine of the vectors to get an information distance The results show that the average information distance of users from different blocks is positively correlated with their social network positions, in which “intermediary role” based on social connection frequency and degree of social interactive connection plays an important role

 The personal information of citizens in criminal law should be treated in the same way as the personal information in general laws Personal information in the crime of infringing on personal information of citizens should not be interpreted restrictedly The basic principles of universal contact and eternal movement determine the mobility of the personal information boundaries The judgment of personal information can be made only by context,because  it is influenced by many factors, such as the person who makes the identification, the purpose of identification, the costs and benefits of  identification, and other sources of information “Combined with other information to identify” is essentially a risk judgment Depending on whether the recipient of the personal information is the public or a specific individual, different standards should be used Information that cannot be identified and cannot be recovered after processing is not personal information, and de-identified information is personal information

The coupling relationships between technological innovation, green finance and industrial policies in energy-saving and environmental protection industry are analyzed from the theoretical perspective Based on statistical data from the year of 2008 to 2015 in China, coupling degree and coordination degree of the two systems and the three systems are calculated using coupling model Then, the grey correlation model is used to calculate the grey correlation among them The results show that the coupling degree of three systems in most years is in accommodation period, and the coordination degree is at the medium level The coupling degree and coordination degree of technological innovation and green finance is lower than the other two systems, which are the bottlenecks of the development of the three systems The grey correlation between technological innovation and green finance is low, and the driving force of the coupling is weak, which lead to the low coupling level Accordingly, the regulatory authorities should enhance the correlation between technological innovation and green finance by establishing the information feedback system and diversified green finance systems

In order to study the mechanism and impact of the innovation-driven development in high-tech industries on China’s economic growth, the generalized method of moments (GMM) is used to study the impact of innovative factors of China’s high-tech industries on economic growth during the period of 1998 to 2016 and to study the regional heterogeneity as well based on the panel data from 29 provinces The results indicate that R&D expenditure in high-tech industries has a significantly positive impact on economic growth, and this effect is more prominent in the western regionExpenditure on R&D personnel  has a negative impact in all regions Expenditure on new product development has a positive effect on economic growth, and the impact is more prominent in the eastern region than that in the central and western regions The number of patent applications has a significantly positive impact on economic growth Overall, the factors of innovation in the high-tech industries can effectively promote economic growth However, the government and enterprises should also pay attention to the accuracy of factor input, improve the efficiency of factor use, focus on regional differences in policies, and encourage independent innovation rather than blindly pursue quantitative expansion

Financing constraints are still one of the most important factors restricting the development of small and medium-sized enterprises (SMEs) In order to measure the degree of financing constraints of SMEs in China, according to the information asymmetry theory and the financial disclosure of the listed companies, this paper selects the alternative indicators to measure the financing constraints of SMEs from the internal factors and external factors, and takes the listed companies in SME Board and the Growth Enterprise Market (GEM) from the year of 2012 to 2016 as the research objects, which are pre-grouped by the size and the age of SMEs The model of measuring financing constraints of SMEs in China is realized through binary logistic regression, and 7 variables from capital structure, profitability, growth ability, shareholding structure and macro-index are obtained However, Tobin’s Q and dividend payout rates commonly used in studies are not currently applicable to the financing constraints research of SMEs in China Since finance charge less than 0 is quite common in SMEs, interest protection multiples is also inadequate for exploring the financing constraints of SMEs in China
