县域旅游经济增长促进经济发展的空间溢出效应及其边界探测
Spatial Spillover Effect and Boundary Detection of County Tourism Economic Growth Promoting Economic Development
摘要
Abstract
The spatial effect of tourism-led growth has long been confirmed by academia;however,the scope of its spatial effect,whether there is a boundary,and its regularity urgently need to be further studied.Based on the Tourism Economic Growth Hypothesis and the"First Law of Geography"hypothesis,using panel data from 88 county units in Guizhou Province from 2010 to 2020,this study tested the spatial spillover effect of county tourism economic growth on economic development based on the spatial panel Durbin model double fixed effect model and detected its spatial attenuation boundary.The research findings are as follows:(1)From 2010 to 2020,the growth of county-level tourism economy in 88 counties and districts in Guizhou Province had a significant positive spatial correlation with the level of economic development and showed stage differences.Based on the spatial panel Durbin model double fixed effects test results,it was evident that the growth of county-level tourism economy had a positive effect on the local economic development level.The growth of county-level tourism economy had significantly improved local economic development.Simultaneously,it achieved spillover and radiation to surrounding areas through spatial spillover,ultimately leading to an overall improvement in regional economic development.In addition,affected by the stage of development,the spillover coefficient of the indirect effects was lower than that of the direct effects,and the direct effects passed more stringent significance tests.(2)The spatial spillover effect of county-level tourism economic growth in Guizhou Province on the level of economic development had a spatial spillover attenuation boundary,and the spatial spillover effect formed an"inverted V-shaped"curve as the geographical distance changed.The minimum spatial spillover boundary for the spatial spillover of county-level tourism economic growth in Guizhou Province was 90 km.The optimal and maximum spatial spillover boundaries were 350 and 450 km,respectively.This study further infers that administrative boundary constraints affect the economic growth of counties in mountainous provinces.The contributions of this study are as follows.First,it revealed the spatial decay law of the spatial spillover effect of county-level tourism economic growth on the level of economic development and detected its decay boundary.Thisstudy verified the hypothesis of economic externalities and the first law of geography,effectively enriching the explanatory power of the"LTGH hypothesis"at the provincial and county levels and addressing the deficiencies in county-level research.Second,by studying this heterogeneity law from the perspective of spatial spillover distance,this study further explored the minimum,optimal,and maximum spatial spillover distance,aiming to facilitate regional spatial collaborative development in different areas,reduce the significant constraints of high time and transportation costs caused by geographical barriers,and provide theoretical and data references for the formulation of policies for high-quality regional collaborative development.关键词
