城市公共自行车因其零排放、灵活性强和可达性高等优点，成为城市公交和地铁之间转换和衔接的重要市内交通工具，也是短距离出行的重要交通方式。基于探索性因子分析，构建了影响使用公共自行车满意度的结构方程假设模型，并以苏州公共自行车为研究对象，通过验证性因子分析，实证研究城市居民使用公共自行车满意度的影响因素。结果显示：①灵活便捷、设计布局、舒适环保和安全是居民使用公共自行车满意度的关键因素，经济成本和运营服务是重要因素。②灵活便捷对满意度影响程度最大，其影响路径系数为0．40，其次为设计布局和舒适环保，路径系数分别为0．39和0．36，安全、经济成本和运营服务影响程度相对较小。③灵活便捷、设计布局、舒适环保、安全和运营服务与满意度表现为正相关，而经济成本与满意度表现为负相关。最后，提出了完善城市公共自行车建设和发展的相关对策，以期为提高公共自行车利用率，真正实现节能环保绿色出行的目标。

英文摘要：

Because of the advantages of zero-emission, strong flexibility and high accessibility, urban public bikes have become an important urban vehicle for conversion and connection between bus and subway, and is also a crucial mode of transportation for short distance travel. By taking Suzhou＇s public bikes as a study object, this paper builds a hypothetical structural equation model of the influence on the satisfaction of using public-bike based on exploratory factor analysis （EFA） and empirically studies the satisfaction and its impact mechanism of urban residents to use public-bike based on confirmatory factor analysis （CFA）. The results are shown as follows. （1） Convenience and flexibility, design and layout, comfortability and environmental friendliness, as well as safety are the key factors of residents＇ satisfaction of using public-bike and economic costs and operational services are important ones. （2） Convenience and flexibility has the greatest influence on satisfaction with the path coeffcient of 0.40, followed by design and layout, comfortability and environmental friendliness, with the path coefficients of 0.39 and 0.36, respectively. The influences of safety, economic costs and operational services are relatively small. （3） Convenience：and flexibility, design and layout, comfortability and environmental friendliness, safety, as well as operational services show positive correlations with satisfaction, while economic costs show a negative one. Finally, countermeasures of improving the construction and the development of urban public-bike are proposed in order to improve the utilization and to achieve the goal of energy conservation, environmental friendliness and green travel.
