旅游发展对绿色经济效率的异质动态效应研究

On the Heterogeneous Dynamic Effect of Tourism Development on Green Economic Efficiency

以2001-2019年我国30个省份的面板数据为样本,采用SBM-undesirable模型测算绿色经济效率,并结合固定效应模型,探究旅游发展对绿色经济效率的异质动态效应。研究发现:我国绿色经济效率整体呈现先下降后上升的“U”型变化趋势,四大板块地区的绿色经济效率空间格局存在差异,地区间差异逐渐缩小,地区内差异有扩大趋势;长期而言,旅游发展与绿色经济效率之间关系不显著,但具有显著的动态性影响,在2010年后旅游发展对绿色经济效率具有显著正向影响;进一步表明,区域异质性检验发现旅游发展主要体现出“锦上添花”作用,即经济发达的东部地区旅游发展的绿色经济效应更为显著。这一结果,为通过旅游发展实现中国绿色经济效率提升的可行性提供理论依据。

Based on the panel data of 30 Chinese provinces from 2001 to 2019,this paper adopted SBM-undesirable model to measure green economic efficiency,combined with fixed-effects models to explore the heterogeneous dynamic effects of tourism development on green economic efficiency.The results demonstrate:(1)the overall green economic efficiency in China showed a U-shaped trend,decreasing first and then increasing;(2)the spatial pattern of green economic efficiency in East China,West China,Central China,and Northeast China indicated difference,which became bigger among them,and tends to be smaller within;(3)in the long term,the relationship between tourism development and green economy efficiency was not strong,but the former had a significant dynamic impact on the latter and the impact showed a significant positive tendency after 2010;(4)regional heterogeneity test further indicates that tourism development mainly had the“icing on the cake”effect,that is,the green economy effect was more significant in economically developed eastern regions.This result provides a theoretical basis for the feasibility of boosting China’s green economy efficiency through tourism development.
