How to play the advantages of network loan platform to reduce the financing costs of net loan platform both in theory and practice has important significance. In this paper, we use the method of qualitative and quantitative combination. First of all, through the interview of the net loan platform practitioners, the financing cost of the net loan platform comes from the internal and external parts. Part of the network loan platform should be righteous, but counterproductive human and material costs, credit costs, information efficiency, transaction costs and matching costs; part of the emerging industry as a challenge, compliance costs, technical costs and safety costs and other cost. And put forward the top design credit system, promote the credit system; build a unified development of regulatory policies to reduce compliance risks; increase investment in technology, share the improvement of technological progress bonuses. Through the establishment of the regression model, the paper analyzes the influence of various indexes of network loan platform on the cost of network reception. It is found that the background of net loan platform with shareholder and executive team as the proxy variable has significant influence on the cost of network loan platform. The effect is not significant. Risk control indicators on the net loan platform cost has a significant negative effect. The impact of operating capacity on the cost of net loan platform differentiation, the acquisition of the cost of positive relations, the other is negative relations. Policy compliance indicators of financial security on the net loan platform cost significantly, the other did not significantly affect the role of liquidity indicators of differentiation, the average borrowing period will significantly affect the net loan platform costs, liquidity is a negative impact. And finally put forward the policy and recommendations and research limitations and future direction.

After the 2008 financial crisis, along with information technology and its application

innovation into the burst period, Shared faster economic growth, and then entered into a

rapid expansion in 2014, quickly penetrate into many areas and market segments.

As the securities industry practitioners and Internet financial practitioners, I am

very concerned about sharing economic model in the development of securities

investment niche. As the Internet and mobile penetration rate rise in recent years, the

Internet financial in the rapid development of our country, investors get used for

investment decision-making information via the Internet. Internet social investment

sharing platform based on knowledge sharing and rapid development, has formed

"opinion leaders", "combined with", "automated financial innovation model". The

emergence of these new patterns, provide investors with investment of knowledge sharing,

the investors behavior changes, many small and medium-sized investors into social

sharing platform for the combination of investment talent information and follow orders,

and centered on investment talent view form fan interaction.

This article around the "Shared economic environment on the impact of portfolio

share on investor behavior research," the theme, the relevant literature and resources, and

to detect Shared economic environment provided by the social share portfolio, whether to

change the traditional information decision and disadvantages of small and medium-sized

investors, whether really improved the small and medium-sized investors return on

investment, its conclusion try to explain the traditional period research literature on active

investment and passive investment, the relevant conclusions of small and medium-sized

investors and institutional investors, sharing in the Internet the rapid development of

economic period is changed.

China's city commercial banks were reorganized by the urban credit cooperatives in the same city in the 1990s. Although they are allowed to open branches outside the registered city, the location and the number of their branches have been strictly restricted. It is fatal to them to increase the competitiveness of their branches. Based on the diversity theory and its mechanism, in this study I examined the impact of source diversity of the senior management in the branches of the city commercial bank on the branches’ productivity and their asset yield. Invoking the resource-based theory and the social capital framework, the source diversity lead to the organization resources diversity and the organization knowledge diversity. The results demonstrate that the source diversity contribute to the branches’ competitiveness advantage. Both internal trained personnel and external introduction personnel are important for the branches’ top management team. But one of the two kinds of personnel is more suitable to their middle management team.

The discussion on the question of integrity has a long history. It is regarded as an important research proposition in the fields of Chinese and Western philosophy, law, sociology, ethics, management and economics. Even though the research results are combined with each other for reference, there is still a lack of comprehensive analysis and empirical study on integrity. In the process of transition from planned economy to market economy, a series of problems have arisen. The problem of dishonesty has caused huge losses to the society as a whole. Therefore, it is of great theoretical and practical importance to conduct a quantitative analysis on the topic of trustworthiness, and investigate the relationship between trustworthiness and the economy.

This paper adopts a game theory model to analyze the reasons for corporate dishonesty, and the problem faced by the regulators. Based on the results from the model, we clarify the duties of various subjects (enterprises, governments and credit organizations) in the construction of a society with integrity.

Then, we analyze different cases of dishonesty and point out the channels through which the economy would be affected by the problem of dishonesty. (1) as an institution, integrity helps reduce the transaction cost and prompt market efficiency; (2) integrity serves as a production factor that influences the economy; (3) integrity will affect the economy by influencing the ability of small and medium enterprises to borrow.

Finally, after we establish the relationship between integrity and the market economy, we use survey data to conduct an empirical analysis on the development of integrity in China. The survey data allow us to build a cycle of integrity risk, and identify the current position in the cycle. Besides, we also compare the region difference regarding integrity, which supports the idea that integrity matters for the economic development.

Because the questionnaires are the only way to obtain the data that can be analyzed at present, the paper not only fills in the research gap caused by the lack of data, but also jumps out of the existing research methods, and enriches the empirical work for the study of integrity.

The recent changes in the software markets gave users an unprecedented number

of alternatives for any given task. In such a competitive environment, it is imperative

to understand what drives user behavior. To that end, the research presented in

this dissertation, tries to uncover the impact of business strategies often used in the

software markets.

The dissertation is organized into three distinct studies into user choice and post

choice use of software. First using social judgment theory as foundation, zero price

strategies effects on user choice is investigated, with respect to product features,

consumer characteristics, and context effects. Second, role of social features in

moderating network effects on user choice is studied. And finally, the role of social

features on the effectiveness of add-on content strategy on continued user engagement

is investigated.

The findings of this dissertation highlight the alignments between popular business

strategies and broad software context. The dissertation contributes to the litera-

ture by uncovering hitherto overlooked complementarities between business strategy

and product features: (1) zero price strategy enhances utilitarian features but not

non-utilitarian features in software choice, (2) social features only enhance network

externalities but not social influence in user choice, (3) social features enhance the

effect of add-on content strategy in extending software engagement.

Given the "New Nine Measures" for capital market reform, a policy document issued by the State Council of China, the development of markets for interest rate derivatives, such as treasury futures, becomes an increasingly important task. Several shortcomings of the existing treasury futures market have been noted: including low market liquidity, singular investor composition, restrict contract terms, and low hedging demand.

This study contributes to a better understanding of the treasury futures market by analyzing changes in China treasury futures market regulations and their impact on market liquidity of treasury futures. Found that compared with the mature market, China treasury futures market exists liquidity shortage, the trading system, market structure and the division of regulatory are factors which influence the liquidity of China treasury futures market.

This study found that reducing transaction costs for further optimization of the width and depth of China treasury futures market are not obvious by using quantitative analysis method, expanding the smallest change price can optimize the market depth, reducing transaction costs and expanding smallest change price can optimize the immediacy, volume and hosting amount. In addition, the bond market will also influence the treasury futures market, the price fluctuations and the morphology of the yield curve of bond market have significant influence on width, depth and holdings of market.

The system of China treasury futures market needs to be optimized by expanding the smallest change price and reducing transaction costs. The market structure needs to be optimized by establishing unified bond market and enriching investor structure.

These findings have significant theoretical and practical implications. The study also provides policy recommendations for the design and establishment of treasury futures market to the regulatory agencies.

During the past decade, the Chinese bond market has been rapidly developing. The percentage of bond to total social funding is constantly increasing. The structure and behavior of investors are crucial to the construction of China’s bond market. Due to specific credit risks, bond market regulation usually involves in rules to control investor adequancy. It is heatedly discussed among academia and regulators about whether individual investors are adequate to directly participate in bond trading. This paper focuses on the comparison between individual and institutional bond investors, especially their returns and risks. Based on the comparison, this paper provides constructive suggestions for China’s bond market development and the bond market investor structure.

By collecting and analyzing more than two million tweets, U.S. House Representatives’ voting records in 111th and 113th Congress, and data from other resources I study several aspects of adoption and use of Twitter by Representatives. In the first chapter, I study the overall impact of Twitter use by Representatives on their political orientation and their political alignment with their constituents. The findings show that Representatives who adopted Twitter moved closer to their constituents in terms of political orientation.

By using supervised machine learning and text mining techniques, I shift the focus to synthesizing the actual content shared by Representatives on Twitter to evaluate their effects on Representatives’ political polarization in the second chapter. I found support for the effects of repeated expressions and peer influence in Representatives’ political polarization.

Last but not least, by employing a recently developed dynamic network model (separable temporal exponential-family random graph model), I study the effects of homophily on formation and dissolution of Representatives’ Twitter communications in the third chapter. The results signal the presence of demographic homophily and value homophily in Representatives’ Twitter communications networks.

These three studies altogether provide a comprehensive picture about the overall consequences and dynamics of use of online social networking platforms by Representatives.

With the fast development of Chinese capital market, an increasing number of institutions and retail investors invest through professional managers. The key to evaluating investment manager’s skill and performance persistence largely lies in portfolio style research and attribution analysis.

The current dissertation takes advantage of a unique dataset, uncover hidden investment style and trading behavior, understanding their source of excess returns, and establishing a more comprehensive methodology for evaluating portfolio performance and manager skills.

The dissertation focuses on quantitative analysis. Highlights three most important aspects. Investment style determines the systematic returns and risks of any portfolio, and can be assessed ex-ante; Transaction can be observed and modified during the investment process; and return attribution can be implemented to evaluate portfolio (managers), ex-post. Hence, these three elements make up a comprehensive and logical investment process.

Investment style is probably the most important factor in determining portfolio returns. However, Chinese investment managers are under constant pressure to follow the market trend and shift style accordingly. Therefore, accurately identifying and predicting each manager’s investment style proves critically valuable.

In addition, transaction data probably provides the most reliable source of information in observing and evaluating an investment manager’s style and strategy, in the middle of the investment process.

Despite the efficacy of traditional return attribution methodology, there are clear limitations. The current study proposes a novel return attribution methodology, by synthesizing major portfolio strategy components, such as risk exposure adjustment, sector rotation, stock selection, altogether. Our novel methodology reveals that investment managers do not obtain much abnormal returns through risk exposure adjustment or sector rotation. Instead, Chinese investment managers seem to enjoy most of their excess returns through stock selection.

In addition, we find several interesting patterns in Chinese A-share market: 1). There is a negative relationship between asset under management (AUM) and investment performance, beyond certain AUM threshold; 2). There are limited benefits from style switching in the long run; 3). Many investment managers use CSI 300 component stocks as portfolio ballast and speculate with CSI500 and Medium-and-Small board component stocks for excess returns; 4). There is no systematic negative relationship between portfolio turnover and investment performance; despite negative relationship within certain sub-samples and sectors; 5). It is plausible to construct out-performing portfolios with style index funds and ETFs.
