摘 要:航空物流业是南昌临空经济区发展的两大核心产业之一,其发展的成功与否直接关系到整个经济区的未来建设,因此对航空物流业发展的影响因素进行定量及定性分析,了解各因素之间的影响关系成为了重中之重。为了避免DEMATEL法、ISM模型的分析结果客观性不足的弊端,从宏观角度出发,采用VAR模型探讨航空物流发展与各影响因素之间的动态关系,在模型检验过程中剔除了变量第二产业增加值,通过脉冲响应和方差分解分析得出,飞机起降架次、进出口总额呈现正向作用,并且贡献率较高,而人均可支配收入带来的影响不明显,且贡献率较低。模型较好地模拟了各个影响因素对航空物流发展的影响,具有一定的现实意义与实证性,因此,VAR模型可以运用于航空物流发展的影响因素分析。

Abstract: Aviation logistics industry is one of the two core industries developing in Nanchang airport economic zone, whose success is directly related to the future construction of the entire economic zone. Therefore, the factors affecting the aviation logistics development are analyzed quantitatively and qualitatively, and learning the relationship between the factors has become a top priority. To avoid the insufficient objectivity of the analysis results of DEMATEL method, ISM model, from a macro point of view, the VAR model is used to explore the dynamic relationship between aviation logistics development and various factors, and the variable secondary industry value added is excluded during the model verification process, through impulse response and variance decomposition analysis, it can be concluded that aircraft movements, total imports and exports show a positive effect and a higher contribution rate, while the impact of the per capita disposable income is not obvious, with the lower contribution rate. The model simulates the impact of various factors on the development of aviation logistics, having certain practical significance and empirical meaning, and therefore, VAR model can be applied to analyze the factors affecting the aviation logistics development.
Key words: aviation logistics; VAR model; impulse response; variance decomposition

南昌临空经济区作为长江经济带—鄱阳湖生态城市群—赣江新区—南昌大都市区战略链条的重要环节以及“一带一路”战略支点,以南昌昌北国际机场及周边服务区为核心,总体格局分为空港枢纽区、集聚发展区和临空辐射区。
航空物流业作为南昌临空经济区的两大核心产业之一,其发展成功与否关系到整个经济区的未来建设。为了达到科学布局发展航空物流业的目的,就必须先对航空物流的影响因素进行定量定性分析,通过运用模型方法进行预测及推演成为了必不可少的手段。……
