The port logistics capacity of countries along the Belt and Road is of great significance to promoting Chinese overseas comprehensive supporting system. The study combines quality data with numerical data to extract the key factors affecting the port logistics development for countries along the Belt and Road. Based on grey correlation analysis and factor analysis, 17 major ports of these countries are evaluated from 11 key factors. The results show that infrastructure, transportation,and entering and leaving costs are crucial for the development of port logistics. The research provides scientific decision-making basis for the construction of an overseas comprehensive supporting system under the context of the Belt and Road Initiative.

Vanishing of Tate Homology - An Application of Stable Homology for Complexes

引用

Acta Mathematica Sinica,English Series 2016年第7期32卷 831-844页

作者： Yan Ping liu Zhong kui liu Xiao Yan YANG Department of Mathematics Northwest Normal University Lanzhou 730070 P. R. China

It has been proved that the vanishing of Tare homology is a sufficient condition for the derived depth formula to hold in [J. Pure Appl. Algebra, 219, 464-481 （2015）]. In this paper, we inves- tigate when Tate homology vanishes by studying the stable homology theory for complexes. Properties such as the balancedness and vanishing of stable homology for complexes are studied. Our results show that the vanishing of this homology can detect finiteness of homological dimensions of complexes and regularness of rings.
