The absolute solution of Jiaojia ERP is put forward, the system models are established, and the solution are explained in detail. The business program of Jiaojia gold mine is reengineered based on the theory of "business centers", and the program-oriented compressed organization is framed. The index group and the solution of mine total quality management are setup. Then the optimize program of SCM and its components are designed on the guidance of "Horizontal Integration". The data of Jiaojia gold mine are reengineered based on the data warehouse technology. The information integration can be available after the establish of the business oriented databases, the subject integration oriented data marts, the application oriented data warehouses, the code databases and metadata, as weil as the OLAP system. The mathematics models and data mining modes are set up to function for the decision support of ERP system. The model of programming Master Production Schedule driven by geological resources and marked is figured out, so as to the models for material requirements planning and other decision supports are set up. The models provide service in forms of model storehouse, method storehouse, and algorithm tools center. The agent center is introduced to process the models' organizing, service, as well as self-study. The function system of Jiaojia gold mine ERP is figured out. By combining the development characteristics of Clients/Server and Browse/Server, the general framework and every sub systems are described in detail, including the function, structure, arrangement, modality, and so on.

Meanwhile, the index futures hedge theory has also get a further development, which evolves from traditional hedge theory, the selectivity hedge theory and modern hedge theories. After analyzing the merits and shortcomings of the three theories, the paper mainly studies four minimum square hedge theory models, which are The traditional static OLS model, VECM model, one variable GARCH(1, 1) model and one variable GJR-GARCH(1, 1, 1) model. Established on September 8th in 2006, China Financial Futures Exchange initiated a new era of our country finance ramification-- index futures, opening a door for the China futures industry.

而股指期货的套期保值理论也随之得到长足发展，历经传统套期保值理论、选择性套期保值理论和现代套期保值理论，本文在分析三大理论优缺点的同时，着重研究现代套期保值理论即最小方差避险理论的四种模型：传统静态OLS模型、VECM模型、单变量GARCH(1，1)模型、单变量GJR—GARCH(1，1，1)模型。2006年9月8日，中国金融期货交易所的成立，掀开了我国金融衍生品种股指期货的新纪元，迎来了中国期货行业发展的机遇期。
