De-fa Cai,Ru-yun Dai,JingCai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.5
GM (n, h) model is the model of grey system modeling, which uses n-order differential equations of h variables. N and h in different models have different meanings and uses[1].Use of model GM(1,1) and model GM(1,h) to tax revenues of the grey system model is established, and applied to the Harbin local tax revenue and the main tax prediction and verification, which provide intellectual support for the local government decision-making is very important [2].At first, this paper forecast the Harbin local tax amount, then respectively to forecast the main tax and inspection (value added tax, business tax, enterprise income tax, individual income tax),Through to the amount of tax and the main tax predicted results of the inspection, show that the prediction error is not big, in line with the actual.
Big Enterprise Tax Risk Management: Warning, Simulation and Application
De-fa Cai,Nan-nan Ni,Jing Cai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.4
Currently, the construction of “promoting tax compliance as the goal, the risk management as the guidance, taking the information tube tax and the hierarchical classification as the basis, set up tax services, risk monitoring, risk response to the new tax management system”, this tax sources of specialized management model has become the direction of the reform of tax system, tax risk management as a new concept received extensive attention of tax authorities. Big enterprises are of the characteristics of small numbers, large scales, huge taxes and contributions, which is the core of tax collecting management. To strengthen the tax risk management ideas, and to direct taxpayers to perfect the inner tax control system are the important measures to implement individual services and pertinent management. This paper presents a flow chart of tax risk control and the four models: the identification model, the measurement model, the response model, the evaluation model, and simulation applications. Here, we take value-added tax as an example. In 2013, China's domestic value-added tax revenue is 2.8803 trillion yuan, accounting for 26% of the total income tax revenue, is one of China's current major taxes. Therefore, based on the data in the CTAIS to analyze the tax burden, and constructs the VAT tax burden warming system, is the effective measures to keep the rapid growth of VAT.

Wei, Wang,Jun, Cai De,Guan, Wan Fa 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
Based on the spectral analysis of the discrete cosine transform (DCT), this paper proposes an adaptive image coding scheme, two activity measurements are designed to classify the image subblocks into four classes, various coding techniques are applied to every class, a good visual quality of the reconstructed image at bit rates of 0.2-0.4 bits/pixel (bpp) is achieved.
