In the research process of the Internet financial risk assessment model, there are two very critical issues to be resolved: one is to determine the index system, and the other is to determine the modeling method. Regardless of the method used, the selection of indicator data is always necessary. The method of index screening based on cluster analysis proposed in this paper uses the clustering of systems to eliminate the correlation between indicators, which plays an immeasurable role in maintaining the importance of each index to the decide variables. Of all the domestic and foreign scholars, a large part of them committed to the financial risks of the Internet. Afsharian, Ahn and Neumann (2016) discussed the problem of input/output factors from the perspective of goal- oriented, revealing the role of input/output factors in DEA, overcoming factors related to factor determination and dual role factors and the choice of adverse factors. A nonconvex programming model was established and a new efficiency definition was defined to provide scalar measurements of the efficiency of each participating unit, as well as reference to multiple outputs for characterizing these procedures and a plurality of input observation data to objectively determine the weight of the method by Charnes, Cooper, & Rhodes (1978) . The duality of these linear programming models provides a new way to estimate the extreme value relationship from the observed data to describe the link between engineering and economic efficiency methods. Jain and Dube (1988) proposed a clustering analysis algorithm, clustering data in the case of prior data classification, the similarity between similar objects, the difference between different classes, and according to similarity difference data to divide. Liu and Lv (2016) used the new DEA model to carry out the “projection analysis” of the weak units with “catch-up efficiency” less than 1 in the Decision unit, and provided the optimal improvement strategy. Taking the typical network loan platform of P2P loan borrower as the research object, Lin (2015) constructs the Z’-P model which can be applied to the risk measurement of P2P loan platform through qualitative, quantitative analysis and the credit risk characteristics of network loan platform. Lv (2016) expounded the impact of Internet finance on joint-stock commercial banks by constructing the generalized DEA model, and gave the countermeasures and suggestions to improve the innovation ability by using a Tobit model. Ma (2012a) proposed that the generalized DEA method is not limited to the all the effective decision- making units reference set, but also includes more unit comparison information such as average units (such as the enrollment mark), low units (such as the tolerable limit) or some special units (such as the selected samples, standards or some special objects). Ma (2012b) proposed the construction of “generalized DEA” theory and method, and then the theory is further applied to multi- attribute decision-making unit evaluation method, fuzzy comprehensive evaluation method, preferred ranking method, risk assessment method, evaluation combination efficiency method, panel data analysis method, system analysis methods, as well as the field of biophysics and other applications. The analytical model of sample data envelopes with preference cone is given by Ma and Lv (2007) , and the distribution characteristics and projection properties of the decision unit in the sample are analyzed. Ma and Zhao (2016) established the generalized DEA model and extended a necessary and sufficient condition for judging the existence of feasible solutions to the generalized DEA model, and the condition that the unit efficiency is overrated. Effectively solve the problem of effective measurement. Ouyang and Mo (2016) pointed out the daily yield data based on the Internet index and the Shanghai Composite Index, moreover, established the Pareto extreme value distribution model and the historical simulation model under the VaR method to measure the financial risk value of the Internet. Finally, concluded that the Internet risk is greater than the risk of the entire stock market. Sha (2015) , who puts forward the opinions of strengthening the internal risk management, external supervision of the platform, standardizing the development of the industry and promoting the financial innovation through analysing the collapse of P2P network loan platform. Si and Sun (2011) use MATLAB to standardize the data and find out the data index with strong correlation to reduce their dimension. Wang and Shi (2016) used CRITIC-gray relational model to construct the Internet financial risk evaluation system, using VaR method to measure the size of Internet risk. Zhang, Ramakrishnan and Livny (1996) proposed the Birch (Blanced Iterative Reducing and Clustering) algorithm to cluster large-scale data sets. The algorithm is a very effective and traditional hierarchical clustering algorithm, which can be effectively clustered with a scan and can effectively deal with outliers.
This paper discusses the Internet financial risk assessment from the aspects of constructing reasonable evaluation index system, efficiency evaluation and classification, “catch-up efficiency” research and projection analysis. Based on the loan data of 95 representative P2P network loan platforms in the top 100, which obtained the net loan home’s rating authentication (of which five companies due to lack of partial data are not yet considered), on the following aspects of the Internet financial risk assessment issues:
Firstly, select the most influential indicators of risk assessment network loan platform. This paper considers 95 network loan platforms 9 indicators of data in February 2017, including the private sector, the banking, the listed companies, the venture capital sector and the state-owned five departments. According to the correlation coefficient of nine index data, R-type clustering is carried out, and evaluation index data are dimensioned and selected from the six indicators which have the core influence on the Internet financial risk.
Secondly, the initial rating and classification of risk control capability efficiency were carried out. Selecting the selected core indicators as input-output system, the article uses the DEA-CCR model to evaluate the comprehensive efficiency value, pure technical efficiency value and scale efficiency value of the network loan platform, and finally obtains the ranking of network loan platform’s comprehensive efficiency, and dividing the platform into the excellent, the good, the medium and the poor four grades according to the defined step size.
Finally, the study on “catch-up efficiency” and projection analysis were carried out. Taking the excellent network loan platform as the reference set, the other non-excellent P2P network loan platforms is used as the evaluation set. The study uses the generalized DEA method to obtain the relative efficiency of other non - excellent P2P network loan platforms, and obtains the catch-up efficiency by the DEA projection formula, gives the feasible path of the transformation of the non-excellent P2P network loan platforms to the excellent P2P network loan platforms.
2. Construction of Evaluation Index System
This paper chooses the network loan platform as the research object, carries on the wind control evaluation research to it. Because of the rapid development trend and the massive scale of China’s Internet finance, the most important is it has an unpredictable influence on our economy. The central bank has made a regulatory system on the network loan platform continuously, which marks the network loan platform has been basically incorporated into the regulatory system. The network loan platform not only plays a fueled role in the development of Internet finance, but also has a great impact on Internet Finance.
The Selection of Indicators
This paper chooses the indicators with the principles of liquidity risk, market risk and credit risk. At present, China’s network loan platform is mainly engaged in the lending business, therefore, this article with reference to the related regulatory system, selecting representative indexes for evaluation study of the financial risk from different dimensions. China’s network loan platform has been showing a rapid development trend continuously, but there are a lot of confusion hidden behind its high-speed development. Then, depending on the characteristics of Internet financial business, dividing the risk evaluation index system into five risk dimensions: operational risk, national risk, liquidity risk, market risk and credit risk. Internet financial industry develops so far. China has managed Internet financial problems exist effectively by building large data and cloud computing, reduced the domestic risk, and Internet Finance has initially formed a unified standardized operating procedure. Most users get a preliminary understanding of Internet finance, reducing the operative risk between consumers and service providers. The article chooses the regulatory principles of liquidity risk, market risk and credit risk to study the financial risks of the Internet, and fully considers the many unpredictable factors such as transaction index and popularity index, which greatly enhances the flexibility of the Internet financial evaluation system. The Internet financial risk evaluation index system constructed in this paper is shown in Table 1, which is a combination of Basel’s requirements for information disclosure of commercial banks, the enhancement of information transparency and the improvement of information asymmetry, taking into account the impact of average expected return rate, average borrowing period and transparency index on the Internet financial risk, and finally different types of data were selected.

According to the final DEA results, the loan platform listed in this paper is divided into four grades: the excellent, the good, the medium and the poor. Then, efficiency of the network loan platform in the department can be derived according to the frequency of the various departments in each level.
3.2.1. Establishment of Decision-Making Unit
Assuming that there are n decision units, each decision unit should have m types of “inputs” (Indicates the cost of “resource” for the decision unit) and s types of “outputs” (They are some of the indicators that indicate “effectiveness” after the decision-making unit consumes “resources”), the input and output data for each decision unit can be given by Table 2.

Here “ ” means that each component is less than or equal to, “ ” means that each component is less than or equal to and at least one component is not equal, and “<” means that each component is less than and does not equal.
3.3. New DEA Model―Generalized DEA Model
Take the excellent network loan platforms as a reference set, and the other network loan platforms as an evaluation set. The generalized DEA model is used to obtain the catch-up efficiency value of the non-excellent network loan platform, and obtain the improvement value of the non-excellent network loan platform according to the projection analysis. Finally according to the excellent platform indicators for the non-excellent platform to provide improved strategy.

4. Empirical Results and Analysis
4.1. Clustering Analysis Model
By using R-type clustering analysis to classify the indicators, the conclusion that there may be a strong correlation between some indexes which can be obtained by qualitatively examining the nine evaluation indexes of the reaction sample network loan platform. In order to verify this idea, using MATLAB software added model to calculate the correlation coefficient, and then further analysis of the problem.
4.1.1. The Standardization of Data Processing
(1) For the average
Calculate the average of the nine-indicator data for the 95 network loan platforms in February 2017, and change the standard to .
(2) Data standardization
In order to ensure the reliability of the results, it is necessary to standardize the data of each index. In practical problems, the measurement units of discrete variables are often dissimilar, in the multi-index evaluation system, the nature, dimension and magnitude of each index are often altered especially. In the case of substantial differences, it will lead to a larger index in the comprehensive analysis has a strong influence if use original data for analysis directly, while the smaller indicators of the impact are smaller. In order to eliminate the dimensional effect of the variables, so that each variable has the same expressive force, and to ensure the reliability of the results, it is necessary to standardize the data of each index. That is
The results of the standardized treatment are shown in Table 3 below:
Table 3. Data after the standardized results.
Data Source: Calculated by MATLAB7.11.0, compiled by the author; Note: Due to space constraints, only part of the platform is listed in Table 3.
4.1.2. Determine the Variable Similarity Measure
In the case of clustering analysis of variables, we should first establish the similarity measure of the variables, which we showed by the correlation coefficient there. The value of the variable x is determined by . Then can use of sample correlation coefficient of the two variables x and y as its variables with similarity. That is:
The correlation coefficient matrix is shown in Table 4 below:
4.1.3. Calculate the Similarity Measure
The similarity of the data index as follows is obtained by using the group average method:
It is equal to the average distance between two sample points, in the formula are the number of sample points in respectively.
Using MATLAB software, get the cluster tree is shown in Figure 1 below.
It can be seen from the cluster diagram that the four indicators have a greater correlation, including the average borrowing period (month), transaction index, popularity index and the index of divergence index. If the nine indicators are divided into three types of risk dimensions: liquidity risk, market risk and credit risk, six core indicators can be selected from nine indicators as well, and it can be used as DEA model of input and output index system for further study. The meaning of the indicator is shown in Table 5 below.

Table 6. P2P network loan companies is three efficiency values and scale income calculation.
All the network loan platforms Table 6 are divided into five departments according to the department, which is divided into five parts: the private sector, the banking sector, the state-owned sector, the listed company sector and the venture capital sector. According to their pure technical efficiency and scale efficiency values, making the following Figures 2-5 of which only two network loan platforms (LUp2p, LLJR) below the banking department, so this is not particularly listed.

4.2.2. Rating Classification
Depending on the comprehensive efficiency values in Table 5, the efficiency of the amplitude “A = the maximum value of efficiency - the minimum value of efficiency”, and A = 0.5976. The step size of the classification is “d = A/n”, according to this step, the network loan platform can be divided into n categories, for the time being referred to in this article 95 network loan platform is divided into four grades, respectively excellent, good, medium and poor, so get the boundaries of the various types were 0.5518, 0.7012, 0.8506. The percentage of frequency distribution as showed in Figure 6, the rating classification frequency distribution is generated as showed in Table 7.
4.2.3. Result Analysis

4.3. New DEA - Generalized DEA Model
Calculation of “Catch-up Efficiency” Based on Generalized DEA Model
Classical DEA method of reference system is an effective decision-making unit, but in fact people need to compare the object is not limited to the outstanding unit, it may be the general unit. Therefore, we use the generalized DEA method to calculate the “catch-up efficiency” value by using the excellent, good and medium network loan platforms as the reference set and the poor network loan platforms as the evaluation set, as showed in Table 8.
4.4. Based on the “Catch-up Efficiency” of the “Projection Analysis”

4.6. Summary of Improvement Measures
In the improvement strategy of poor network loan platform to excellent, good, medium network loan platform as a reference set respectively, however, the average expected yield and the registered capital should be reduced on the basis of the original amount, the leverage index, the dispersion index, the liquidity index, the transparency index and other indicators on the basis of the corresponding increase in the amount.
The corresponding improvement measures proposed for the poor network loan platform are based on the generalized DEA results, including reduced registered capital, average expected yield and increased leverage index, liquidity index, dispersion index and transparency index, etc. In view of the connotation of these factors and the network loan platform to improve or reduce the meaning of an index, this paper gives the following recommendations:
5.1. Establish Risk Early Warning Mechanism
Put risk control in the forefront of the development process. Currently, China’s network loan platform itself is more rapid development, but there are still many problems. One of the most serious problems is the high risk of high interest rates on the network loan platform. Therefore, the network loan platform in the conduct of investment, should take full account of the safety of assets, within the scope of the law of normal business assets, Based on the investor’s own good economic level and risk resistance, to minimize the risk of capital investment. In the development process not only to take the opportunity, but also need to timely resist the risk, the risk control on the first place. While reducing risk while increasing capital liquidity while improving profitability and asset volume.
5.2. Improve Service Levels
Play the role of human capital in the network loan management platform, especially the senior management staff. Improve the level of grassroots staff. Improve service levels to improve customer experience, cultivate high-quality customer base, establish a good reputation, in order to improve the network loan platform volume. And can also be appropriate to reduce the intermediate costs, to promote the occurrence of borrowing and lending transactions, to achieve the purpose of improving the transaction index.
5.3. Increase the Proportion of Long-Term Debt
Increase the proportion of long-term liabilities in total assets. Capital leverage is equivalent to the net debt ratio refers to the ratio of long-term debt and shareholders, capital leverage is small, indicating that the debt of the company’s low degree of capitalization, long-term debt pressure is small; On the contrary, this shows that the company’s debt capitalization is high, long-term debt pressure increases. Long-term debt is relatively stable, repayment in the next few fiscal years, so the company will not face a lot of liquidity risk, the debt pressure is small at a shorter period of time. The network loan platform can use long-term debt to raise fixed assets and expand their operations. Therefore, the platform may be appropriate to increase the proportion of long-term liabilities in total assets, the use of leverage bi-directional multiplier, to achieve a small investment to get a big return.
5.4. Improve the Transparency of Funds
The network loan platform shall promptly disclose the relevant financial information to the public. Transparency is an aspect of good funding, but transparency is not an end in itself, it is a means of promoting efficiency, ensuring that regulatory organizations and network loan platforms take responsibility. Increased transparency of funds includes transparency in the system, transparency of accounting and transparency of indicators. In order to improve the transparency of the network loan platform, the network loan platform shall promptly disclose the financial information to the public, including the detailed description and necessary financial matters, including the detailed structure of the network loan platform, the functional structure of the network loan platform, clear the legal basis, and so on. The loan platform should promptly publish the financial analysis of the forecast indicators, including the financial structure and the cyclical balance, the financial sustainability (basic stable debt), the expected return period average period, etc., in order to select the most suitable loan platform for investors and borrowers, in order to achieve short-term, medium and long-term funds transparent.
This paper starts from the study of nine indicators in February, 2017, from the selection of private sector, banking sector, listed company sector, venture capital sector and state-owned loan platform. Firstly, the MATLAB model is used to classify R-type clusters according to the correlation coefficients of nine index data, and six important indexes are selected to reduce the dimension. And then we use the DEA method to establish the input and output system of the selected indicators, and use the DEA method to evaluate the comprehensive efficiency value, the pure technical efficiency value and the scale efficiency value of the network loan platform. From this, we can draw the comprehensive efficiency of the network loan platform ranked the top five were LUp2p, SOUYIDAI, Eastlending, 51jbb and HONGLING CAPITAL. Secondly, according to the definition of the step size, what will be studied by the 95 network loan platform is divided into excellent, good, medium and poor four grades, of which there are 21 excellent platforms and twenty-two good platforms; there are twenty-one medium platforms and the rest is poor. Finally, the excellent, good, and medium network loan platforms as a reference set, the last ten poor network loan platforms as an evaluation set, figure out the relative efficiency of the last ten poor loan platforms by using the generalized DEA. According to DEA projection, analysis of the worst ten network loan platform improvements for the poor network loan platform reforms direction and path to provide the best strategy, such as reducing average expected yield and registered capital, increased leverage index, liquidity index and so on.
