基于面板数据的城市绿化与旅游业发展关系研究

Relationship between urban greening and tourism development based on panel data

选取淮海经济区20个地级市2006～2016年的旅游和绿地等相关指标组成的面板数据,通过变系数固定效应模型进行回归分析,探究城市绿化对旅游经济的影响状况,以期为经济和生态环境可持续发展提供借鉴.研究表明:淮海经济区整体城市绿化对旅游经济的影响作用较为显著,人均公园绿地面积对旅游经济的影响带动作用远高于建成区绿化覆盖率;每个地级市的建成区绿化覆盖率对旅游经济的影响系数差异很明显,存在明显的空间分异现象;从人均公园面积与国内旅游收入的相关系数来看,除安徽宿州、山东枣庄与泰安3个地级市未通过5%水平下的t检验,其他17个地级市的人均公园绿地面积与国内旅游收入均存在正相关.人均公园面积的空间差异性不如建成区绿化覆盖率明显.

In order to provide references for the sustainable development of economy and ecology,based on the panel data of tourism and green space of 20 cities in Huaihai Economic Zone from 2006 to 2016,the impact of urban greening on tourism economy was explored by regression analysis with variable coefficient fixed effect model.The results show that the overall urban greening in Huaihai Economic Zone has a significant impact on tourism economy,and the per capita park green area has a much higher impact on tourism economy than that of the built-up area green coverage.And the influence coefficient of green coverage on tourism economy in the built-up areas of each prefecture-level city is obviously different,and there is obvious spatial differentiation.Moreover,according to the correlation coefficient between per capita park area and domestic tourism income,except for Suzhou in Anhui,Zaozhuang and Tai an in Shandong,three prefecture-level cities did not pass the t-test at the level of 5%.The per capita park area of other 17 cities had positive correlation with domestic tourism income.The spatial difference of park area per capita is not as obvious as that of built-up area.
