人力资本作为最重要的生产要素之一,是经济增长的重要源泉。采用Penn World Table 9.0数据(WPT 9.0),从直接影响与间接效应两个方面对OECD成员国在1990—2014年期间人力资本对经济增长的贡献展开实证测算。研究表明:人力资本对经济增长...人力资本作为最重要的生产要素之一,是经济增长的重要源泉。采用Penn World Table 9.0数据(WPT 9.0),从直接影响与间接效应两个方面对OECD成员国在1990—2014年期间人力资本对经济增长的贡献展开实证测算。研究表明:人力资本对经济增长具有显著的直接影响,并通过提高劳动力素质和物质资本质量对经济增长产生显著的间接效应;总贡献中,69.70%来自直接影响,30.30%来自间接效应。因此,从直接与间接效应两个方面对人力资本的作用进行科学评估,对于科学制定人力资本政策以促进国民经济持续健康增长具有重要的实践意义。展开更多

Similarly, cryosphere change has numerous impacts on the natural ecosystem and human society, which may resemble an indirect influence of climate change. These two types of impacts, in shared fields, are distinguished in space and time by effective mechanisms and processes. Climate change has positive and negative impacts on some systems, which may be adjusted by cryosphere change. These indirect and direct impacts may be distinguished, and then correct policies and measures can be made against these changes.展开更多

文摘Climate change has major impacts directly on the natural ecosystem and human society, of which the cryosphere is most easily affected be-cause of its frangibility and sensitivity. Similarly, cryosphere change has numerous impacts on the natural ecosystem and human society, which may resemble an indirect influence of climate change.
