In this paper we establish an equilibrium model of intra-product specialization dominated by MNCs, and perform some empirical tests of China's trade volume growth using variables including technological conditions of trade, extent of similarity of economies, policy conditions of trade, extent of disintegration of production and level of per capita capital equipment; the empirical results support our basic conclusions.

In the part of empirical analysis of Chinese IPO first-day return, the difference between existing study and this study is that we use principal components analysis to extract from five factors to construct investors'sentiment index, add it to controled varibles, on which we examine the influence of offering mechanism on IPO first-day return. Moreover, we gather statistics and compare the IPO holding return for lockup period between fixed-price-class offering method and bookbuilding-class offering method, as well as price range between Chinese A-share market and Hongkong stock market, which prvide comprehensive evidence to appraise Chinese IPO bookbuilding mechanism. 2. Compare to the existing literatures which consider discount or allocation, incentive allocation and discount are considered at the same time in optimal mechanism design in this dissertation, and the offering bottom price is introduced to the price range. We investigate the relationship between price range and allocation quantity, and obtain the optimal price range and allocation strategy so that the advantages of independent allocation are reflected. On the other hand, the disadvantages of independent allocation are reflected in the manipulation in case of no restriction on IPO allocation. To distinguish from the existing literatures, bookbuilding mechanism is introduced to the model. We study the allocation strategy adopted by the underwriter in the pooling equilibrium of manipulation. In addition, we analyze the incentive compatibility conditions to which the existence of pooling equilibrium should satisfy and examine some factors'impact on the existence of manipulation.3. In bookbuilding without independent IPO allocation, Chinese realistic IPO background is considered and the condition of bookbuilding and fixed-price hybrid offering is added. Divide bookbuilding and fixed-price hybrid offering into sequential hybrid and simultaneous hybrid, and point out that the key points of subscription strategy in the two kinds of hybrid are different. Through modeling and simulation we obtain the impact of institutional investors'subscription strategy on bookbuilding without independent IPO allocation, which fill the gap in related research. Moreover, in the part of IPO bookbuilding with over-allotment option, the pricing strategy is divided into hot-IPO strategy and weak-IPO strategy. Take into account the procedure of Chinese IPO with over-allotment option, it presents how the underwriter determines the pricing strategy and what effect it brings to offering price and issue size through modeling and simulation. Therefore, it is instructive as a complement to existing literatures.

Distribution ratios of complex extraction for different operation conditions were forecasted. Using mass action law, the liquid-liquid equilibrium models of complex extraction of monobasic and polybasic carboxylic acid have been successfully induced, and physical extraction were also considered in the model. On the basis of orthogonal experiments, the models of equilibrium distribution ratios were established. The processes of complex extraction were tested and verified. Comparing experimental data with model values, it could be held that the regression precision of model was rather high and the model supplied fundamental data for industrial amplification and practical use of complex extraction.

In chapter3, information is divided into two basic types, the marginal equation of bond price and short-term interest variations is established, thus the security price variations and the price equilibrium of other assets (risk security non-risk security are included) are analyzed by the implement of portfolio Theory. Finally the bond value equation which takes equilibrium return as its yield Parameter is established through the theory of comparative return. In chapter 4, the intra-information and the transferable system of price is emphasized and the market-maker model and expected model under non-perfect information market conditions are established, and the disaccord of the influence of extra-information and intra-information on the security price is discussed.
