【摘要】：為了能夠全面系統(tǒng)地評(píng)價(jià)海上通道關(guān)鍵節(jié)點(diǎn)的安全保障效率及應(yīng)急效率,在兩階段DEA模型的基礎(chǔ)上,考慮負(fù)投入產(chǎn)出變量、決策者對(duì)于2種不同效率的偏好差異及效率分解,構(gòu)建了海上通道關(guān)鍵節(jié)點(diǎn)安全保障效率與應(yīng)急效率評(píng)價(jià)模型,并將其應(yīng)用到16個(gè)海上通道關(guān)鍵節(jié)點(diǎn)的安全保障效率及應(yīng)急效率評(píng)價(jià)中.研究結(jié)果顯示,龍目海峽和霍爾木茲海峽的效率始終是非有效的,且隨著α值的增加,曼德海峽、蘇伊士運(yùn)河和望加錫海峽也會(huì)轉(zhuǎn)變成非有效單元.除此之外,朝鮮海峽,霍爾木茲海峽和英吉利海峽3個(gè)關(guān)鍵節(jié)點(diǎn)的子系統(tǒng)效率值波動(dòng)不明顯,安全保障系統(tǒng)占據(jù)主體,而馬六甲海峽和龍目海峽2個(gè)單元的子系統(tǒng)效率值存在部分不規(guī)律的變化.
[Abstract]:In order to comprehensively and systematically evaluate the safety and security efficiency and emergency efficiency of the key nodes in the sea channel, based on the two-stage DEA model, considering the negative input-output variables, the decision makers' preference differences and efficiency decomposition for the two different efficiencies are discussed. The evaluation model of the safety and emergency efficiency of the key nodes in the sea channel is constructed and applied to the evaluation of the safety and emergency efficiency of the 16 key nodes in the sea channel. The results show that the efficiency of Longmen Strait and Hormuz Strait is always non-effective, and with the increase of 偽 value, the Mande Strait, Suez Canal and Wangkassi Strait will also be converted into non-efficient units. In addition, the efficiency of the three key nodes in the Korean Strait, Hormuz Channel and the English Channel does not fluctuate significantly, and the security system occupies the main part. However, the sub-system efficiency values of Malacca Strait and Longmu Strait have some irregular changes.
