在资源环境约束下,改善金融资源配置效率是促进全要素生产率增长,实现地区经济可持续发展的关键。以一个改进的三部门内生增长模型为基础,通过构建金融资源扭曲度与全要素生产率关系的非线性动态面板回归模型,探究金融资源错置对全要素... 在资源环境约束下,改善金融资源配置效率是促进全要素生产率增长,实现地区经济可持续发展的关键。以一个改进的三部门内生增长模型为基础,通过构建金融资源扭曲度与全要素生产率关系的非线性动态面板回归模型,探究金融资源错置对全要素生产率带来的直接效应和间接效应。结果显示,金融资源错置并不一定完全导致全要素生产率的减损,这取决于本地经济发展状况;在我国,金融资源错置通过直接效应引致全要素生产率减损0.802 1%,并分别通过对人力资本市场、外商直接投资市场和对外贸易市场产生抑制作用,间接带来全要素生产率的减损,减损度分别为-0.324 0%、0.633 5%、0.122 0%。 展开更多

The Ms8.0 Wenchuan earthquake on May 12, 2008 caused heavy casualties and economic loss. According to the field investigations, the characteristics can be described as follows: The meizoseismai region with an intensity of XI shows an obviously zonal distribution and suffered serious destruction from the earthquake, and the destruction perpendicular to the earthquake surface rupture decreased sharply. At the same time, the intensity X and IX regions perpendicular to the rupture are narrow and therefore their coverage area is small. The intensity on both sides of the rupture attenuates rapidly, but intensity VII and the VI regions are wide, the latter covering about 240,000 km^2. In intensity VI region, the damage area perpendicular to the rupture in the southern part is much larger than that of the northern part. Also, much new understanding about destruction types and destructive modes for all kinds of buildings, landforms and terrain is achieved in this paper. 展开更多

Methods: A total of 42 rabbits and 10 rats were served as the experimental animals. A slow recompression decompression test and an explosive decompression test were applied to the animals, respectively. And the effects of the given tests on the animals were discussed. Results: The slow recompression decompression did not cause an obvious lung injury, but the explosive decompression did cause lung injuries in different degrees. The greater the decompression range was, the shorter the decompression duration was, and the heavier the lung injuries were. Conclusions: Explosive decompression can cause a similar lung injury as shock wave does. The primary mechanical causes of the lung injury might be a tensile strain or stress in the alveolar wall and the pulmonary surfaces impacts on the inside wall of the chest. 展开更多
