长期的地区"经济封闭"造成京津冀地区城镇体系综合布局的空白,因此,城镇体系至今没有合理的职能分工,产业雷同,互争互斗、缺少联合发展与区域结构化,造成京津冀地区整体经济发展与世界及全国先进地区相比差距越来越大.本文拟从交通建设的角度,探讨其对京津冀地区协调发展的影响. 相似文献

F. A. HAYEK 《Economic Affairs》1982,2(3):135-142
Are the communist economies strong or weak? Russia bristles with arms and uses strong language. But is the socialist economy flawed at the center? Professor Hayek here argues, against the Polish economist Oskar Lange (Polish Ambassador to the USA, 1945–6, subsequently Chairman of Poland's State Economic Council), that without markets the efficient use of scarce resorces is not feasible. Is this why the Polish economy is now in turmoil? 相似文献

Correlated equilibrium constitutes one of the basic solution concepts for static games with complete information. Actually two variants of correlated equilibrium are in circulation and have been used interchangeably in the literature. Besides the original notion due to Aumann (1974), there exists a simplified definition typically called canonical correlated equilibrium or correlated equilibrium distribution. It is known that the original and the canonical version of correlated equilibrium are equivalent from an ex-ante perspective. However, we show that they are actually distinct – both doxastically as well as behaviourally – from an interim perspective. An elucidation of this difference emerges in the reasoning realm: while Aumann’s correlated equilibrium can be epistemically characterized by common belief in rationality and a common prior, canonical correlated equilibrium additionally requires the condition of one-theory-per-choice. Consequently, the application of correlated equilibrium requires a careful choice of the appropriate variant. 相似文献

Two families of kurtosis measures are defined as K
1(b)=E[ab
−|z|] and K
2(b)=E[a(1−|z|b)] where z denotes the standardized variable and a is a normalizing constant chosen such that the kurtosis is equal to 3 for normal distributions. K
2(b) is an extension of Stavig's robust kurtosis. As with Pearson's measure of kurtosis β2=E[z
4], both measures are expected values of continuous functions of z that are even, convex or linear and strictly monotonic in ℜ− and in ℜ+. In contrast to β2, our proposed kurtosis measures give more importance to the central part of the distribution instead of the tails. Tests
of normality based on these new measures are more sensitive with respect to the peak of the distribution. K
1(b) and K
2(b) satisfy Van Zwet's ordering and correlate highly with other kurtosis measures such as L-kurtosis and quantile kurtosis.
