The study finds:①the international airports in China is still at a relative low level of overall technical efficiency,and pure technical inefficiency is the main cause of the airport inefficiency;②the international airports development of every region in China is not in balance;③.
研究发现:我国对外开放机场总体上生产效率较低,纯技术无效率是其主要成因;东部地区对外开放机场生产效率最高,依次为中部、西部和东北地区;枢纽机场生产效率明显高于非枢纽机场;机场全要素生产率总体上呈现逐年改善的趋势,主要源于综合技术效率变动和技术进步的双重作用;跑道长度、候机楼面积、每架次飞机完成的货邮吞吐量、区域经济发达程度、枢纽机场地位以及位于省会及计划单列市均是影响机场生产无效率的重要因素。
