| Abstract: | We consider a competitive two-dimensional risk model. Two different types of ruin probabilities and the state process are defined for insurance market. In terms of some results of classical risk model and the property of conditional expectation, the expression of two types of ruim probabilities for insurance market and each insurance company are deduced and the distribution of the state process is obtained. |
