Influence of Chinese economic fluctuations on tourism efficiency in national scenic areas

This article measures and calculates tourism efficiency in Chinese national scenic areas. In order to analyse the characteristics of multi-scale fluctuations, the empirical mode decomposition (EMD) and wavelet decomposition methods are adopted. Specific Chinese national scenic areas are divided into several zones, with conclusions provided about the impact of economic fluctuations on their tourism efficiency. The results are as follows. The tourism efficiency of Chinese national scenic areas overall is not high; most have not yet reached data envelopment analysis (DEA) optimization; and the quasiperiodicity of scenic areas' tourism efficiency mainly fluctuates between 2.42 and 9.67 years. Owing to the effects of extraneous factors, the significance of pure technical efficiency declined, which illustrates that economic development could promote technological progress, but technological progress is not a sufficient and necessary condition of economic development; studies of different periods show that a downward economic fluctuation will also facilitate technological improvement and promotion, which is the embodiment of the inverse periodicity of technological progress.
