This paper studies the systematic level of international trade under the background of global economic crisis.
本文以全球经济危机为大背景,首先从系统经济学角度简要分析了全球经济危机持续时间的主要影响因素,然后将重点放在国际贸易系统化水平研究上;其次,利用字典序原理方法在二维空间上研究系统化水平,用贸易额和贸易顺差两个变量分析了各国贸易系统化水平状况;第三部分通过加入名义因素,将系统化水平的研究由二维空间推广到三维空间,然后借助相对贸易规模和平衡因子对贸易系统化水平重新进行度量,把问题的研究降到了一维实数空间,并计算出了全球经济系统的关键子网所包含的国家和地区个数。
The drainage capacity of vitical drains has been paid more attention in the past,but drainage capacity of horizontal drainage system has been overlooked.
以往较注重竖向排水系统排水能力的研究,而忽略了对水平排水系统排水能力的研究。
