以全国、广东省、中山市1995 - 2007年的数据描述三级政府规模与经济增长的变化情况,并用菲德模型检测各级政府规模对经济增长的差异性影响.研究结果表明,各级政府规模变化轨迹并非简单的扩大或缩小,而是呈运动变化势;省、市地方政府规模对经济增长的决定性作用不显著,中央政府显著;各级政府部门的边际生产力低于非政府部门的边际生产力;各级政府的消费性支出对经济增长产生外溢效应,其中市级政府的消费性支出对经济增长产生负外溢效应. 相似文献

自然法是洛克早年在牛津大学时期关注的论题。自然法也就是人类的“本性法”,是与理性的本质相符的“理性法”。在洛克那里,它使自然状态被合理地推定为事实,同时也是人类进入政治社会后订立成文法的依据。因此,对于一个研究洛克政治哲学的人而言,探究他的自然法思想,是一项无法回避的准备性工作。 相似文献

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. Unlike previous studies, we use patent data to examine the evolution of two competing bleaching technologies in five major paper-producing countries, both of which reduce the use of chlorine in the pulping process. The use of patent data allows us to focus on the invention stage. However, adoption data are also presented, and by the end of the 1990s, nearly all pulp production in these countries used one of these technologies. While previous studies emphasize the importance of regulation for inducing innovation, here we find substantial innovation occurring before regulations were in place. Instead, pressure from consumers and the public at large to reduce the chlorine content of paper drove invention, prior to the introduction of environmental policies in any of the countries concerned. 相似文献
