Property protection,financial constraints and economic growth

The relationship between financial system, law framework or economic growth has attracted considerable attention for years. However, there are some questions still remaining unanswered: between tangible assets protection and intellectual property protection, which is more important? Between external financing and property rights protection, which does play a greater role for the economic development? According to the dynamic stochastic general equilibrium(DSGE) model with non-free market factors, we study the effectiveness of property protection and external financing, and try to answer these questions. The model fits the data well, and we find:(1) protection of intellectual property plays a more important role than that of tangible asset, in the promotion of economy;(2) relaxation of financial constraints on corporate is more effective in the short run, while the protection of intellectual property is more effectual in the long term.     

探讨公路工程造价控制与管理的策略

随着我国社会经济不断发展和交通路网规划逐步完善,近年来我国公路建设速度日益加快,公路建设投资也越来越大,目前我国公路总里程数达到世界之最.但是在公路工程建设过程中,存在许多关于工程项目建设和造价控制问题,只有对这些问题加以重视,才能真正建成让国家满意和人民放心的优质工程.在对公路工程进行管理的过程当中,造价控制与管理是非常重要的,要将造价控制与管理落实到公路工程建设的每一个阶段,才能使公路工程建设的质量得到有效保证.公路工程建设具有它的特殊性,一是工程建设周期长,二是建设资金投入大,三是在建设过程中不确定因素多.因此在工程建设初期就对公路工程的造价进行确定,是不合理的也是不科学的,只有在公路工程建设的各个阶段对公路工程造价进行控制与管理,并及时采取各种有效造价控制措施,才能真正确定工程项目造价,真正做到造价控制与管理.
