Online social networks are an integral element of modern societies and significantly influence the formation and consolidation of social relationships. In fact, these networks are multi-layered so that there may be multiple links between a user' on different social networks. In this paper, the link prediction problem for the same user in a two-layer social network is examined, where we consider Twitter and Foursquare networks. Here, information related to the two-layer communication is used to predict links in the Foursquare network. Link prediction aims to discover spurious links or predict the emergence of future links from the current network structure. There are many algorithms for link prediction in unweighted networks, however only a few have been developed for weighted networks. Based on the extraction of topological features from the network structure and the use of reliable paths between users, we developed a novel similarity measure for link prediction. Reliable paths have been proposed to develop unweight local similarity measures to weighted measures. Using these measures, both the existence of links and their weight can be predicted. Empirical analysis shows that the proposed similarity measure achieves superior performance to existing approaches and can more accurately predict future relationships. In addition, the proposed method has better results compared to single-layer networks. Experiments show that the proposed similarity measure has an advantage precision of 1.8% over the Katz and FriendLink measures.

Henan is a populous province in China, and its banking system is sound. The development of local banks plays an significant role in economic development of Henan Province. For these factors, some suggestions are presented, such as increasing capital accumulation rate reasonably, improving the management of credit risk, realizing the diversification of profits and controlling cost-income ratio effectively. 1 Background Economic globalization promoted the rapid development of Finance since 1990s.A variety of (Various) financial products were introduced in 2013, and government significantly introduced various financial reform policies[1][2]. On February 28, 2015, the central bank announced that the deposit and loan interest rates would decreased by 0.25% form March 1st 2015, and China's financial reform process continued to accelerate. Every economic agents' need for financial system was enhanced under the market economic system, and local banks having crisis would cause a certain impact on China's economy[3][4]. Evaluating the financial risks of local banks, finding out the important factors which influenced them in Henan Province could be effectively control the financial risks[5].

The coordinated development of The Guangdong, Hong Kong and Macao Greater Bay Area (Greater Bay Area) has already been a national strategy, and its plan is about to be introduced. One important factor that constrain the coordinated development of Greater Bay Area is that there has not yet built a sound coordination mechanism for interests, which is still not breaking the mindset of "a tiny piece of land". In terms of interest coordination mechanism, the most important thing is the adjustment of fiscal and taxation policies. Since the coordinated development of Greater Bay Area has entered into a critical period of comprehensive advancement and key breakthroughs, reform and innovation of fiscal and taxation policies are needed in many aspects, such as industrial reconciliation and upgrading, ecological environment co-construction and sharing, technology-driven innovation and traffic facilities construction. In the process of achieving regional coordinated development of Greater Bay Area, the market helps to allocate resources, but the role of the market has certain limitations in regulating economic operations and the distribution of production factors. As an important tool to regulate the distribution of economic and resource factors, fiscal taxation policies can make up for the shortcomings of market regulation Studying the current fiscal and fixation policies under the background of coordinated development and improving the fiscal and taxation policies that hinder regional coordinated development provide some help to promote the coordinated development of Greater Bay Area.

At present, with the new urbanization as the background of the situation in our country, local governments in China especially in the central region as the representative of Henan Province, is to take this opportunity to create their own economic heights and industrial agglomeration, and constantly improve the level of urbanization of the original, but the town level cannot improve open the power of capital, the local government of is facing financing, financing platform, financing channels and financing policy and a series of financing systems caused by financing difficulties. Therefore, as the perspective of the local government, a new study of investment and financing system and the risk measure, can more effectively guide and encourage the existing capital city infrastructure and public services to improve the field.
