基于C-D生产函数的民航运输业投入产出关系实证研究

依据我国1985年至2018年民航运输业的民航运输总周转量、民航飞行员数量和民用运输飞机架数等数据，基于Cobb-Douglas生产函数建立民航运输业投入产出数学模型，在此基础上构造向量误差修正模型对数据进行预测，并运用脉冲检验考察模型的长短期均衡和系统动态特性，结果发现：民航运输业中的投入和产出呈正相关及长期均衡关系，资本投入对产出增长的贡献作用大于劳动投入对产出的贡献作用。最后，给出了民航运输业现阶段发展的相关建议与结论。

The Input-Output Relationship of Civil Aviation Transportation Based on C-D Production Function

In order to explore the input-output relationship of the civil aviation transportation industry, based on China''s civil aviation transportation industry related data from 1985 to 2018, the total turnover of civil aviation transportation is used as the output, the number of civil aviation pilots is used as labor input, and the number of civil transport aircraft is used Is the amount of capital invested. First, establish a mathematical model of the input and output of the civil aviation transportation industry based on the Cobb-Douglas production function; second, construct a vector error correction model on this basis to predict the data; and again, use the pulse test to investigate the long- and short-term equilibrium and system dynamics of the model Characteristics; the results found that: the input and output of the civil aviation transportation industry are positively correlated and long-term equilibrium relationship, the contribution of capital input to output growth is greater than the contribution of labor input to output. Finally, some suggestions and conclusions about the development of the civil aviation industry are given.
