Research On The Evaluation System And Model Of Listed Companies' Internal Control Quality

Since the 21 st century,with the explosion of the Global Financial Crisis,the construction of company internal control has gotten widespread attention around the world.The Ministry of finance,Securities and Futures Commission as well as other departments in our country also started to strengthen the supervision on Internal Control,they put Internal Control on the position same as Financial Reports,and issued a series of regulations,guidelines and standards to the problems existing in the internal control of the Listed Companies in China.Nevertheless,these policies were kind of ineffective on the evaluation of Internal Control Quality Information.Then in such situation,to develop the evaluation of Internal Control quality of the Listed Companies is becoming more necessary.Based on this point,this thesis begins normatively analyze which aims to build a set of generally applied quality evaluation system and model of the Internal Control of the Listed Companies.Firstly,in the aspect of quality evaluation of Internal Control,this thesis collects and analyzes previous related papers,and defines the quality of the Internal Control of Listed Companies,reveals the principle of the evaluation of Internal Control quality of Listed Companies.Secondly,In the aspect of evaluation system and model,after constructing the quality evaluation index system of the Internal Control of Listed Companies which is combined of qualitative and quantitative items,this thesis combine the G1 model based on Subjective Weighting Method with Entropy Weighting Method model based on Objective Weighting Method and set up a synthetical evaluation system using CCR model based on DEA to carry out effective evaluation.And then,In the aspect of empirical research,this thesis selects the data of 200 Listed Companies on the mainboard of A-share from 2012 to 2014 to simulate the model,by the empirical results it come to conclusions that the higher synthetical evaluation score enterprises got,the more related efficiency it is about the Internal Control and Operational Performance.Finally,in terms of suggestions,this thesis proposes advice from Supervision Department,Enterprises Internal Management and Investor Behaviors those three views to improve the quality of the Internal Control of listed companies according to the simulated results.Innovation Points in this thesis including:(1)Putting forward the framework of the evaluation theory of Internal Control quality of the Listed Companies by combining of Comprehensive Quality Management Theory,Principal-agent Theory,Corporate Management Theory,Game Theory,and Signal Transmission Theory and others of Economics and Management.(2)On the basis of Comprehensive Risk Management Theory,combining the internal control elements and objectives,then the index system of the evaluation of Internal Control quality of the Listed Companies with the combination of qualitative indexes and quantitative indexes has been constructed.(3)On the basis of the index system of the evaluation theory of Internal Control quality of the Listed Companies,proposing the model of the evaluation of Internal Control quality of the Listed Companies,which is using the method of Synthetically Evaluation by combining G1 model with Objective Weighting Method to weight indexes and calculate the evaluated results,and using DEA model to measure the efficiency of Internal Control of the Listed Companies.
