With the recognition and finance support from Chinese government, we have got the great achievements in the fields of conservation, evaluation, and utilization of kenaf germplasm. China has got much attention in the word because of having the largest kenaf germplasm gene bank. The germplasm resources of kenaf have played an important role in promoting breeding and development of production in the past years. This paper reviewed the status of kenaf production, collection and conservation, utilization of kenaf germplasm, in the study and utilization of put forward strategies of utilization .This will provide kenaf industry. evaluation, innovation and we also discussed the problems genetic diversity of kenaf, and sustained development and available experiences for the展开更多

First, a stochastic model of a small open economy is constructed. Second, the equilibrium solutions of the representative agent's stochastic optimization problem are derived.

文摘This paper employs a stochastic endogenous growth model with productive government expenditure in a small open economy to analyze the optimal fiscal policy. First, a stochastic model of a small open economy is constructed. Second, the equilibrium solutions of the representative agent's stochastic optimization problem are derived. Third, we obtain the equilibrium solutions of the central planner's stochastic optimization problem and the optimal government expenditure policy. Finally, the optimal tax policy is characterized.
