摘要: 为强调港口与城市生产运营的连续性及其对港口城市可持续发展的重要性,本研究将港口城市构建成一个综合的复合系统。采用网络SBM-DEA模型,以绿色GDP为期望产出,纳入环境保护成本作为绿色投入考量,并选用二氧化碳排放量作为非预期产出,以此全面评估辽宁省各港口城市“港-城”复合系统的生产效率,进而深入探讨其可持续性发展水平。研究结果显示:1)观测辽宁港口城市全局的分阶段生产效率,发现城市的“投入-产出”的转化效率一直显著高于港口效率;2)不同港口城市在各个时间段内的生产效率呈现波动趋势,揭示“港-城”系统运行的复杂性和动态性;3)基于SBM-DEA模型的深入分析,揭示“港-城”系统内部协调性的不足。大连为城市可持续发展城市,营口和锦州为港口可持续发展城市,盘锦与葫芦岛为可持续发展一般城市,丹东为可持续性较差城市。提出针对各个港口城市特定情况的、具有实践可行性的策略建议,旨在促进整个辽宁省港口城市的均衡、绿色及可持续发展路径。

Abstract: To stress the importance of continuity of ports and cities' operation on their sustainability, this paper establishes a comprehensive compound system of port city, and uses SBM-DEA model which takes green GDP as desired output, environmental protection costs as green inputs, carbon dioxide emission as non-desired output to systematically evaluate productivity of port-city compound system of port cities in Liaoning province, and discusses its sustainability. Phased productivities of the overall Liaoning port city show that urban inputs/outputs conversion rate is largely higher than port. Productivities of port cities show a waving trend in a time range, suggesting a complexity and dynamic of port-city operation. SBM-DEA model suggests an insufficient “port-city” internal coordination. Dalian is a city of sustainability, Yingkou and Jinzhou of port sustainability, Panjin and Huludao of average sustainability, and Dandong of poor sustainability. This paper presents suggestions for each port city with the purpose of promoting a balanced, green and sustainable path in Liaoning's port cities.

Key words: SBM-DEA model, efficiency evaluation, sustainable development, Liaoning's port cities
