     Since the 2010s, a lot of Chinese students in Japan seem passive to communicate with Japanese. For verifying the reason of this fact, it’s necessary to understand about the structure of the personal network of Chinese students in Japan. Most of Chinese students were born in the era of one-child-policy in China, and more and more Chinese go to study abroad at their parents’ expense. Furthermore, Chinese students usually get in touch with their parents by Chinese social networking service (such as “Wechat”), and the frequent use of Chinese SNS makes their personal networks based on their parents in China stronger.

     This paper focuses on the personal network of Chinese students studying in Japan, and attempts to make clear that how the Chinese family structure effects Chinese students’ personal networks in Japan

     This paper tries to find characteristics of municipalities’ open data policy through quantitative content analysis on open data related context in municipalities’ general plan. Specifically, first, for the municipalities that are registered in DATA.GO.JP and have reference to open data in their general plan, we confirm their descriptions about open data. Second, frequently mentioned terms were extracted by morphological analysis on these descriptions. Then we carry out principal component analysis on these terms and extract principal components. Finally, we point out characteristics of some municipalities’ open data policy based on the result.

     PPP/PFI projects are policy instruments that are vital in the effective and efficient implementation of social capital improvement and management and of economic revitalization, as part of the macro-economic policy guidelines of Japan, including “The Basic Policy on Economic and Fiscal Management and Reform (also known as the “big-boned policy”)” and “The Japan Revitalization Strategy”. In light of this, there is a need to conduct regular and continuous assessments of the extent of the effects these projects have on macro-economics. For this purpose, it is a critical issue that information relating to these projects is made public and understood comprehensively, and that an understanding is gained of how these projects are reflected in the Japanese System of National Accounts (JSNA), the contents of which are both “Fundamental Statistics” and Japanese Accounting Standards, and of how they can be compared.

     In order to do this, it is necessary to gain a comprehensive understanding of PPP project expenditures throughout Japan, and link these to the JSNA system to make such comparisons possible. However, laws and guidelines regulating PPP projects do not currently exist, and it is difficult to gain a comprehensive understanding of the number and scale of the projects.

     Since its passage into law in 1999, the Act on Promotion of Private Finance Initiatives (PFI law) has spawned 740 business projects with a combined contract value of 6.2 trillion yen. This study examined PFI projects that have publicly disclosed their details and collected data which can be obtained from the financial statements, etc., of Special Purpose Companies (SPCs) that have been specially established for the implementation of these businesses in an attempt to quantify the business volume of the projects. It was found that the statistical records that have been kept are effective.
