【摘要】：隨著金融業(yè)的蓬勃發(fā)展，我國(guó)金融業(yè)面臨越來(lái)越多的安全風(fēng)險(xiǎn)。其中，，將非法收入以各種形式注入金融體系的洗錢(qián)犯罪活動(dòng)也在快速增長(zhǎng)，給國(guó)家和社會(huì)帶來(lái)了巨大危害。為了規(guī)避此類(lèi)風(fēng)險(xiǎn)，確保我國(guó)金融業(yè)健康持續(xù)發(fā)展，建立健全的中國(guó)反洗錢(qián)監(jiān)控體系也顯得日益重要。從目前掌握的案例來(lái)看，洗錢(qián)犯罪活動(dòng)主要表現(xiàn)為犯罪分子將非法收入通過(guò)銀行和保險(xiǎn)公司等金融機(jī)構(gòu)，并利用其產(chǎn)品的復(fù)雜性將其轉(zhuǎn)化為合法收入。 目前，我國(guó)保險(xiǎn)業(yè)反洗錢(qián)監(jiān)控手段停留在依據(jù)法律規(guī)定設(shè)定篩選條件，但是保險(xiǎn)企業(yè)自身對(duì)大額和可疑交易的篩選并無(wú)創(chuàng)新。本文著眼于我國(guó)保險(xiǎn)業(yè)反洗錢(qián)監(jiān)控的應(yīng)用研究，根據(jù)既定的法律法規(guī)及保險(xiǎn)公司的反洗錢(qián)經(jīng)驗(yàn)數(shù)據(jù)，在現(xiàn)有的數(shù)據(jù)挖掘技術(shù)研究基礎(chǔ)上，重點(diǎn)對(duì)決策樹(shù)主要算法展開(kāi)研究，本論文的主要成果概括如下： 利用決策樹(shù)CHAID算法、CART算法和QUEST算法對(duì)大額和可疑交易的相關(guān)關(guān)系進(jìn)行分析，以獲得影響大額和可以交易識(shí)別結(jié)果的因素。然后，在此基礎(chǔ)上，通過(guò)設(shè)立錯(cuò)分成本對(duì)模型進(jìn)行進(jìn)一步分析，使得模型結(jié)果擬合度提升，最終根據(jù)模型結(jié)果使得保險(xiǎn)企業(yè)能獲得更加具體的篩選條件。實(shí)驗(yàn)數(shù)據(jù)表明，CHAID算法、CART算法和QUEST算法的模型擬合度基本持平，但是在大額和可疑交易識(shí)別的準(zhǔn)確率上均未能達(dá)到理想水平。因此，本文在原有基礎(chǔ)上進(jìn)一步優(yōu)化模型，設(shè)立錯(cuò)分成本，重新使用CHAID算法擬合模型，準(zhǔn)確率大幅提高，具體表現(xiàn)為將大額和可疑交易的對(duì)象錯(cuò)分為良好信用客戶(hù)的概率低于15%。 在大額和可疑交易的篩選自變量范圍中添加投保與退保天數(shù)間隔及繳費(fèi)模式，并將之應(yīng)用到現(xiàn)行保險(xiǎn)業(yè)反洗錢(qián)監(jiān)控系統(tǒng)中。分析了兩種篩選情況的結(jié)果差異，證明了改進(jìn)后的篩選條件能提高篩選的覆蓋率和準(zhǔn)確率，最后以此給出了對(duì)于保險(xiǎn)業(yè)反洗錢(qián)系統(tǒng)政策上和技術(shù)上的建議,具有一定的現(xiàn)實(shí)意義。
[Abstract]:With the vigorous development of financial industry, China's financial industry is facing more and more security risks. Among them, the crime of injecting illegal income into the financial system in various forms is also growing rapidly, which brings great harm to the country and society. In order to avoid such risks and ensure the healthy and sustainable development of China's financial industry, it is increasingly important to establish a sound anti-money laundering monitoring system in China. According to the current cases, the criminal activities of money laundering mainly show that the criminals turn the illegal income through banks and insurance companies, and use the complexity of their products to convert it into legal income. At present, China's insurance industry anti-money laundering monitoring means stay in accordance with the provisions of the law to set screening conditions, but the insurance companies themselves to large and suspicious transactions screening has not been innovative. This paper focuses on the application research of anti-money laundering monitoring in insurance industry in China. According to the established laws and regulations and the anti-money laundering experience data of insurance companies, and on the basis of the existing data mining technology, this paper focuses on the research on the main algorithms of decision tree. The main achievements of this paper are summarized as follows: the correlation between large amount and suspicious transactions is analyzed by using decision tree algorithm cart and request algorithm to obtain the factors that affect the results of large amount and transaction identification. On this basis, the model is further analyzed by setting up a misdivisional cost, so that the model result fit is improved, and finally the insurance company can obtain more specific screening conditions according to the model results. The experimental data show that the model fitting degree of cart algorithm and quest algorithm is basically the same, but the accuracy of large amount and suspicious transaction recognition is not up to the ideal level. Therefore, this paper further optimizes the model on the basis of the original, sets up the misdivision cost, reuses the Chaid algorithm to fit the model, and the accuracy is greatly improved. The concrete performance is that the probability of classifying the objects of large amount and suspicious transaction into good credit customers is lower than 15%. In the range of screening independent variables of large and suspicious transactions, the interval of days between insurance and withdrawal and the mode of payment are added, and applied to the current insurance anti-money laundering monitoring system. The differences between the two screening conditions are analyzed, and it is proved that the improved screening conditions can improve the coverage and accuracy of the screening. Finally, the policy and technical suggestions for the insurance anti-money laundering system are given. Has certain realistic significance.
