Measurement of Economic Contribution of Small and Medium Airports and Its Enlightenment to Region Economic Development

Abstract

Based on the study of the influence mechanism of airports on regional economic development, this paper empirically analyzes the interaction between small and medium-sized airports and regional economic development by using the data of Mianyang Nanjiao airport from 2002 to 2017, in order to provide measurement methods and theoretical support for local governments to encourage and promote the development of local airports. In the part of empirical analysis, firstly, this paper constructs the air transport scale index system of small and medium-sized airports and the evaluation index system of regional economic development. Then, the entropy method is selected to select the key factors of the airport, so as to obtain the airport transportation capacity equivalent, and the principal component analysis method is used to extract the high load index of the regional economic system. Finally, this paper establishes the SVAR model of airport transportation capacity and regional economic relationship, carries out structural impulse response and variance decomposition analysis, draws the conclusion that small and medium-sized airports have a positive impact on regional economic development, but not significant, and analyzes the reasons.
