According to the domestic and foreign scholars on the research status of GFRP concrete column, the hollow reinforced concrete column confined by GFRP tube was put forward as a new type of member. Three hollow GFRP reinforced concrete columns were designed, and the compression capacity under three kinds of reinforcement ratio through the static test method was investigated. At the same time, the simulation analysis was carried out on the specimens combining with the finite element software ANSYS, a reference for practical engineering was provided. The results show the bearing capacity of specimen increased with the increase of reinforcement ratio, but not linear relationship. With the increase of reinforcement ratio, the confinement effect of composite columns increased firstly and then decreased. When the longitudinal reinforcement ratio of the new type of composite columns was 0.9%, the loading mechanism was best, and the confinement effect by the GFRP tube was largest.

The stock price is influenced by many factors. The share ratio in circulation, the size of company, per share earnings and net asset value per share were considered as the important indexes which decide the stock price. Feltham-Ohlson model was expanded, and the empirical result indicates that the share ratio in circulation effects on the stock price negatively and the other three indexes also influence the price largely. In the implementing moment of the reform of dual-class equity structure, the impact of the share ratio in circulation to stock price, to provide reference for the listed companies to make their financial policies was studied, for the investors to make their reasonable decisions, for the short-term investors to make sensible choice from the aspect of negotiability.
