The term used in embodiments of the present invention is only to be not intended to be limiting merely for for the purpose of describing particular embodiments
The present invention.In the embodiment of the present invention and the "an" of singular used in the attached claims, " described " and "the"
It is also intended to including most forms, unless the context clearly indicates other meaning.
Fig. 1 shows the flow chart of the loan risk evaluation method of one embodiment of the present of invention.
As shown in Figure 1, the process of the loan risk evaluation method of one embodiment of the present of invention includes:
Step 102, the risk assessment type of target user is obtained, wherein the risk assessment type includes evaluation before loan
It is assessed with after loan.
Specifically, it can judge whether target user is in loan status by target user personal information etc., if
Target user is in loan status, then illustrating, which should be at this time after target user borrows, assesses, i.e. the risk assessment of target user
Type is to assess after borrowing；If target user is not in loan status, illustrate that target user not yet provides a loan at this time, Ying Jinhang
Evaluation before loan, i.e. the risk assessment type of target user are evaluation before loan.
Step 104, according to the risk assessment type, corresponding loan risk evaluation model is selected.
Assessment has respectively corresponded respective loan risk evaluation model after evaluation before loan and loan, due to influencing loan qualification
Factor is different from the factor of loan repayment capacity is influenced, therefore the credit risk assessed after the loan risk evaluation model of evaluation before loan and loan
Risk assessment rule in assessment models is different.
Often only carry out evaluation before loan in the related art, to judge whether user has loan qualification, however, to
After family is made loans, the income situation of user is likely to change, and for debt transferor, still has greater risk,
And the risk is different from the risk faced when the loan qualification for borrowing preceding verifying user, therefore, in the technical scheme, joined
It is assessed after loan, to monitor the loan repayment capacity and risk of user during user refunds.
Step 106, the common reserve fund for obtaining the target user pays information.The common reserve fund pays information
In pay total duration, pay total amount, single pays the time, single pays the amount of money, turn over unit and pays ratio, these public affairs product
Gold pays information can be in the ability to work of respective dimension embodiment target user, income, income situation of change etc., and it is accurate to facilitate
Carry out loan valuation.Diversified common reserve fund pays the stabilization journey that information can be paid in the common reserve fund that multiple dimensions embody user
Ability is spent and paid, to provide the Rule of judgment of multiple dimensions for risk assessment, helps to promote risk evaluation result
Accuracy.
Under normal circumstances, often relatively stable and of certain scale work unit just can carry out common reserve fund for employee and pay
Receive, thus the common reserve fund of user pay situation paid than social security in the related technology, the rigid condition such as amount received, can more embody
The income degree of stability of user.Therefore, common reserve fund is paid into the foundation that information is assessed as evaluation before loan and after borrowing, it can be into one
The validity of assessment result after step increases evaluation before loan result and borrows.
Step 108, information is paid according to the loan risk evaluation model and the common reserve fund, calculates loan risk evaluation
As a result.
The common reserve fund of target user is paid into the corresponding loan risk evaluation model of information input, passes through loan risk evaluation
Loan risk evaluation result is calculated in assessment rule in model, wherein assessment rule can carry out flexibly according to actual needs
Setting and change.
By above technical scheme, assessed after increasing loan, convenient for obtaining refund during user is in refund in time
The variation of ability keeps loan transferor more perfect to the control of credit risk, meanwhile, common reserve fund is had chosen as loan valuation
Foundation, improve the reliability of loan valuation result, further, also commented based on loan risk evaluation model realization loan
The automation estimated saves Manpower Estimate's cost, and improves the reliability of assessment result.
Before step 102, need to assess rule for different loan risk evaluation model settings, specifically, comprising:
Obtain rule setting information；It is regular for loan risk evaluation model setting assessment according to the rule setting information,
In, the evaluation before loan is corresponding with evaluation before loan rule, and assessment assesses rule after being corresponding with loan after the loan.Evaluation before loan rule
Flexible setting and change can be all carried out according to actual needs with rule is assessed after loan.After making loans user, the receipts of user
Enter situation to be likely to change, therefore, borrowing the risk that front is faced is to verify the loan qualification of user, and borrowing the risk faced below is
Verify whether user persistently has loan repayment capacity, the assessment content of the two is different, therefore, borrows front for accurate evaluation and faces
Risk and borrow the risk faced below, need to be respectively evaluation before loan and that the different assessment of setting is assessed after borrowing is regular.
In a kind of implementation of the invention, system provides the setting of many kinds of parameters of assessment rule, and user passes through defeated
Enter information or selected to come many kinds of parameters of manual setting assessment rule in the information that system provides, to adapt to the reality of user
Border demand.
It, can be according to user's due to the information such as the occupation of user, age difference in another implementation of the invention
The information such as occupation, age are respectively that a set of assessment parameter of regularity, and the occupation by system according to user, year is arranged in different user group
The information such as age select a set of assessment rule for this user in predetermined more set assessment parameter of regularity, to reduce user's operation,
Promote the convenience and crowd's adaptability of loan valuation.
Below on the basis of Fig. 1 embodiment, regular borrowing is assessed to evaluation before loan rule and after borrowing by Fig. 2 and Fig. 3
Application in money risk assessment is described in detail respectively.
As shown in Fig. 2, the process of the loan risk evaluation method of another embodiment of the invention, comprising:
Step 202, when the risk assessment type of target user is evaluation before loan, it is total to obtain paying for the target user
Duration, pay total amount, single pays the time, single pays the amount of money, turn over unit and pays ratio.
Step 204, predetermined total duration and first difference for paying total duration of the target user are calculated.
Predetermined total duration has high-quality the minimum of repaying ability for target user and pays total duration, in paying for target user
In the case that total duration is greater than or equal to predetermined total duration, illustrate that user has high-quality repaying ability, at this point, the first difference is negative
Number can generate weakening to risk assessment value before final loan.Conversely, paying total duration less than predetermined total duration in target user
In the case where, illustrate that user does not have high-quality repaying ability, at this point, the first difference is positive number, risk before final loan can be commented
Valuation generates reinforcement.
For example, predetermined total duration is 3 years, the total duration of paying of target user is six months 2 years, i.e., 2.5 years, then first
Difference is 0.5.
Step 206, predetermined total amount and second difference for paying total amount of the target user are calculated.
Predetermined total amount has high-quality the minimum of repaying ability for target user and pays total amount, in paying for target user
In the case that total amount is greater than or equal to predetermined total amount, illustrate that user has high-quality repaying ability, at this point, the second difference is negative
Number can generate weakening to risk assessment value before final loan.Conversely, paying total amount less than predetermined total amount in target user
In the case where, illustrate that user does not have high-quality repaying ability, at this point, the second difference is positive number, risk before final loan can be commented
Valuation generates reinforcement.
For example, single predetermined total amount is 3.6 ten thousand yuan, the total amount of paying of target user is 30,000 yuan, then the second difference is
0.6 ten thousand.
Step 208, the time is paid according to the single of the target user and the single pays the amount of money, determined respectively
The postponement number of the target user and pay insufficient number.
The single of January in office is paid single in the time and is paid if the amount of money is 0, illustrates that target user disconnected pays in this month
Common reserve fund is primary, and it is that twice, and it is that single pays the amount of money twice of last month, then says that in one's duty single in January in office, which pays the time,
Bright target user is primary in this month postponement common reserve fund.The postponement number of target user and to pay insufficient number more,
Illustrate that the stability of its work income is poorer.Postponement number and to pay insufficient number be zero or positive number, when being zero to loan before
Risk assessment value can increase risk when being positive number without influence, generate reinforcement to risk assessment value before final loan.
For example, it is 0 that target user, which paid the namely disconnected number of paying of insufficient number in 2.5 years, postponement number is 1 time.
Step 210, unit is turned in described pay according to the target user described in several in total duration, calculates institute
State the job-hopping frequency of target user.
Unit is more paying turning in total duration by target user, illustrates that the stability of its work is poorer, more it is possible that
Influence its repaying stability.Therefore job-hopping frequency is positive number, can increase risk, generates reinforcement to risk assessment value before final loan.
For example, target user is paying in total duration 2.5 years tool there are two unit is turned over, illustrate its frequency of job-hoping be 1 time/
2.5 years, that is, 0.4 times/year.
Step 212, ratio is paid according to the target user and the single pays the amount of money, calculates the target
The monthly income number of user.
It is higher that the single of target user pays the amount of money, and pays that ratio is higher, illustrates that the income of target user is higher, explanation
The repaying ability of user is more secure.Conversely, it is lower then to illustrate that the repaying ability of target user ensures.
For example, it was 0.1 ten thousand yuan that the single of target user, which pays the amount of money, in 2.5 years First Years, ratio of paying is 0.2, then
The monthly income number for illustrating user is 0.5 ten thousand, is risen in 2.5 years second years, and user's job-hopping is primary, and single, which pays the amount of money, to be become
0.12 ten thousand yuan, ratio of paying is 0.2, then illustrates that the monthly income number of user rises to 0.6 ten thousand.
Step 214, according to the monthly income number, the target user is calculated in the monthly income paid in total duration
Change rate.According to examples detailed above, it is 1.2 that target user, which is calculated, in the monthly income change rate for paying total duration.
Step 216, by first difference, second difference, the postponement number, described pay insufficient time
Several, the described job-hopping frequency and monthly income change rate obtain corresponding percentage risk respectively multiplied by corresponding risk factor.
For example, setting first difference, second difference, the postponement number, it is described pay insufficient number,
The job-hopping frequency and the corresponding risk factor of monthly income change rate are respectively 0.15,0.2,0.25,0.4,0.2, -0.2, corresponding
Risk factor absolute value it is bigger, illustrate that its influence to risk assessment value before borrowing is bigger.
Step 218, by first difference, second difference, the postponement number, described pay insufficient time
Several, described job-hopping frequency percentage risk corresponding with monthly income change rate is added, and obtains risk assessment value before borrowing.According to above-mentioned
Example, calculating 0.15*0.5+0.2*0.6+0.25*1+0.4*0+0.2*0.4+ (- 0.2) * 1.2 obtain risk assessment value before borrowing and are
0.285。
In addition, high risk range, low-risk range and high-quality repaying limit of power can be set to borrow preceding risk assessment value, it is high
Risk range, low-risk range and high-quality repaying limit of power be respectively less than 0.5, more than or equal to 0.5 and less than 1, be greater than
Or it is equal to 1.Risk assessment value 0.285 belongs to high risk range before then borrowing in examples detailed above.
By above-mentioned evaluation before loan rule, it can effectively evaluate whether target user there is enough abilities to repay the loan, mention
The reliability of loan valuation result is risen.
Fig. 3 shows the flow chart of the loan risk evaluation method of yet another embodiment of the present invention.
As shown in figure 3, the process of the loan risk evaluation method of yet another embodiment of the present invention includes:
Step 302, when the risk assessment type of target user is evaluation before loan, the single for obtaining the target user is paid
Deposit the time, single pays the amount of money, turn over unit and pays ratio.
Step 304, single pays the amount of money during according to the target user, single pays time and loan during loan,
Insufficient number is paid during postponement number and loan during determining the loan of the target user respectively.
Time interval due to this to assess after loan, therefore assessing is determining, is that target user starts the month repaid
To current month.The single of January in office pay single in the time pay the amount of money be 0 if, illustrate target user in this month
Disconnected common reserve fund of paying is primary, and it is that twice, and single pays twice that the amount of money is last month that in one's duty single in January in office, which pays the time,
Then illustrate that target user is primary in this month postponement common reserve fund.It the postponement number of target user and pays insufficient number and gets over
It is more, illustrate that the stability of its work income is poorer.Postponement number and to pay insufficient number be zero or positive number, to loan when being zero
Risk assessment value is without influence afterwards, and can increase user when being positive number can not continue loan returning risk, to risk assessment value after final loan
Generate reinforcement.
For example, target user pays the namely disconnected number of paying of insufficient number from repaying in 2 years so far be 0, postponement
Number is 1 time.
Step 306, unit is turned over described in several according to the target user during loan, calculates the target and uses
It job-hops during the loan at family frequency.
Unit is more for target user's turning over during repaying, illustrates that the stability of its work is poorer, is more possible to influence
Its repaying stability.Therefore job-hopping frequency is positive number, can increase risk, generates reinforcement to risk assessment value after final loan.
For example, tool illustrates that its frequency of job-hoping is 1 time/2 years there are two unit is turned over to target user in 2 years from repaying,
It is exactly 0.5 times/year.
Step 308, the amount of money is paid according to single during paying ratio and the loan during the loan of the target user,
Calculate monthly income number during the loan of the target user.
Step 310, according to monthly income number during the loan, monthly income becomes during calculating the loan of the target user
Rate.
It is higher that the single of target user pays the amount of money, and pays that ratio is higher, illustrates that the income of target user is higher, explanation
The repaying ability of user is more secure.Conversely, it is lower then to illustrate that the repaying ability of target user ensures.For example, repaying 2 years
First Year, it is 0.1 ten thousand yuan that the single of target user, which pays the amount of money, and ratio of paying is 0.2, then illustrates that the monthly income number of user is
0.5 ten thousand, in the second year repaid 2 years, user's job-hopping is primary, and single, which pays the amount of money, becomes 0.12 ten thousand yuan, and ratio of paying is 0.2,
Then illustrate that the monthly income number of user rises to 0.6 ten thousand, finally, monthly income variation of the target user during repaying is calculated
Rate is 1.2.
Step 312, insufficient number, the loan will be paid during postponement number, the loan during the loan
Period job-hop frequency, during the loan during monthly income number and the loan monthly income change rate respectively multiplied by corresponding wind
Dangerous coefficient obtains corresponding percentage risk.
It job-hops frequently during paying insufficient number, the loan during the loan during postponement number, the loan
During rate, the loan during monthly income number and the loan the corresponding risk factor of monthly income change rate be respectively 0.2,
0.4,0.15, -0.2, the absolute value of corresponding risk factor is bigger, illustrates that its influence to risk assessment value after loan is bigger.
Step 314, the postponement number, insufficient number, the job-hopping frequency and the monthly income paid are changed
The corresponding percentage risk of rate is added, and obtains first threshold.
According to examples detailed above, calculating 0.2*1+0.4*0+0.15*0.5+ (- 0.2) * 1.2 and obtaining first threshold is 0.035.
Step 316, risk assessment value before the loan of the target user is obtained into second threshold multiplied by predetermined ratio.
Predetermined ratio may be configured as 0.12, calculates 0.12*0.285 (calculated result from Fig. 2 embodiment) and obtains second threshold.
The calculating to risk assessment value after loan is added in risk assessment value before borrowing, and can efficiently use in preceding calculated result,
In conjunction with risk before loan and after borrowing, risk assesses the loan repayment capacity after of user together, facilitates the meter of risk assessment value after promotion is borrowed
Accuracy is calculated, convenient for reducing credit risk.
Step 318, the difference for calculating the first threshold Yu the second threshold, as risk assessment value after loan.According to
Examples detailed above, is calculated first threshold and second threshold is 0.0008, i.e. first threshold is greater than second threshold, illustrates that target is used
The job stability and/or income level at family are increased after loan, but based on risk assessment value 0.0008 after borrowing it is found that target
The job stability of user and/or the growth of income level are considerably less, and loan repayment capacity is still in more beneath level after borrowing.
By above technical scheme, risk assessment value is effectively embodied after capable of calculating loan in conjunction with preceding risk assessment value is borrowed
The change direction and amplitude of variation of the repaying ability of target user facilitate further the repaying feelings of control target user in time
Condition makes risk resolution strategy, to reduce credit risk.
