摘要
将非期望投入引入松弛变量模型,提出基于时间窗的非期望要素松弛变量方法,评价2010年~2015年海上丝绸之路关键海峡/运河的安全效率,并分析安全效率的差异变化,探究影响安全效率的关键因素.实证结果表明,海上丝绸之路战略实施后,海峡/运河的安全效率有所提升;马六甲海峡安全效率最高,而曼德海峡安全效率最低;船舶通行量,船舶事故和海盗等是影响安全效率的主要原因.
Undesirable inputs are introduced into the slacks-based measure（SBM） model. A slacks-based measure of undesirable factors based on windows is proposed to evaluate the safety efficiency of the key straits and canals along the maritime silk road during the period of 2010~2015, and the differences of the safety efficiencies and main factors affecting the efficiencies are analyzed. The results show that efficiency improves after the maritime silk road strategy is implemented, and the best efficiency is that of Strait of Malacca, yet the worst is that of Strait of Bab al Mandab. Traffic volume, marine incidents, and piracy are the main factors that influence safety efficiency.
