In general, this paper includes several parts, shown as the following: The first part summarizes the background and outline of stock index future and introduce briefly its local status and CSI 300 stock index future contract. The second part has a retrospect of the main academic papers of both local or overseas, and also a discussion of relevant hedge strategies and models, to lay a solid theoretical foundation for the empirical analysis and test for the operation process of hedge in latter parts. The third part outlines the principle, key factors and real operation process of hedge. Moreover, it makes a empirical analysis on popular hedge models with HK Hang Seng index. In the end, it test the hedge effect of trading on IF0706, CSI 300 stock index future contract, with CCB select-growth securities fund as present underlying. The fourth and also the last part, explores how to define hedge ratio in china mainland market. It includes the stability test ofβfor local securities portfolio, adjustment of historicalβand best data length for estimation of historicalβ, etc. Also, the thesis makes some beneficial experiments on the definition of best data length for estimation of historicalβ, survey of fashion forβand variation for industryβs. Fortunately, it's got some meaningful results.

The data in LLE are optimized using the small world algorithm, and the shortest path and the local neighbor set clustering coefficients are used as the local parameters. As a result, the problem of the embedding distortion using only local linear patch of the manifold to define neighborhood in Euclidean space is effectively solved. Three groups of standard data sets are selected to test and to compare the efficiency and robustness of SLLE and LLE.

A fine-grained genetic algorithm based algorithm which is for the parameters optimization problem of agent model is proposed. The fine-grained genetic algorithm is used to solve the parameters optimization problem of agent model. As to the parameters optimization problem of the agents colony model, the first step is to define the concept of "the parameters mode of the combat agents colony" to describe the parameters of the combat agent colony model. Then the genetic algorithm is used to solve the optimization problem with the parameters mode of the combat agent colony model as the genetic individual. Besides the algorithm, the algorithm dispatch tactic is also considered. And the two level sequence dispatch tactic and the two level nesting dispatch tactic are put forward for those complex parameters optimization problem. At last, the model parameters optimization under antagonism codition is studied. The means to solve this problem is to translate it into a kind of antagonism problem, then use the competitive co-evolutionary genetic algorithms to solve it.
