旅游发展对农村人居环境质量的门槛效应——基于安徽省城市模型的研究

The Threshold Effect of Tourism Development on the Quality of Rural Living Environment—Research Based on Urban Model of Anhui Province

以安徽省16个地级市为例,运用门槛回归模型研究旅游发展对农村人居环境质量的非线性影响。结果表明:(1)安徽省旅游发展主要集中在皖南地区,皖北地区旅游业发展水平较低,两个地区存在明显的空间差异性,并有逐年扩大的趋势;(2)安徽省农村人居环境质量在时间上波动不大,整体呈现南高北低的空间分布;(3)旅游发展对农村人居环境质量的影响随旅游收入密度的增加呈现系数逐渐减小的上升趋势。至2020年,旅游收入密度小于3112.6746的城市,其旅游业的发展对农村人居环境具有显著提升作用;旅游收入密度大于3112.6746但小于6645.4197的城市,其旅游业的发展对农村人居环境的提升已难以起到显著效果;旅游收入密度大于6645.4197的城市,其旅游业的发展对农村人居环境的改善已微乎其微。

Taking 16 prefecture-level cities in Anhui Province as an example,a threshold regression model is used to study the nonlinear impact of tourism development on the quality of rural living environment.The results show that:(1)The tourism development in Anhui Province is mainly concentrated in the southern region of Anhui,while the tourism industry level in the northern region of Anhui is relatively low,with obvious spatial differences and a trend of increasing year by year;(2)The quality of rural living environment in Anhui Province has not fluctuated significantly over time,with an overall spatial distribution of high in the south and low in the north;(3)The impact of tourism development on the quality of rural living environment shows an increasing trend of decreasing coefficient with the increase of tourism income density.By 2020,for cities with a tourism income density less than 3112.6746,the development of the tourism industry has a significant improvement effect on rural living environment;For cities with a tourism income density greater than 3112.6746 but less than 6645.4197,it is difficult for tourism to have a significant effect on improving rural living environment;For cities with a tourism income density greater than 6645.4197,the improvement in rural living environment has been minimal.
