旅游业高质量发展是推进中国式现代化的重要基础和有力支撑,科学测度和评价区域旅游业高质量发展水平及其变化趋势具有重要的理论和现实意义。在界定旅游业高质量发展内涵的基础上,以新发展理念和可持续发展理论为指导,构建旅游业高质量发展评价指标体系,并对中国30个省份的旅游业高质量发展水平进行测度与评估。研究表明:2011—2019年中国旅游业高质量发展水平总体呈现逐年上升趋势,产业发展水平、社会和谐水平、创新能力、文旅融合程度、生态保护水平均得到明显提升,2020—2021年受新型冠状病毒感染疫情影响,虽然总体发展水平和产业发展水平有所下降,但其他四大指标得分均持续上升,反映了中国旅游业高质量发展水平随着我国高质量发展进程而不断提升。但是各省份之间旅游业高质量发展水平差异明显,总体发展质量处于中等水平,距离高质量发展标准仍有较大差距。未来提升旅游业高质量发展水平应重点从优化产业结构、提高旅游创新质量、深化文旅融合、加强生态保护等方面入手。

中国古代士人不断探索对不遇焦虑的调适与消解途径。嵇康“乐道闲居”,追求“逍遥”的人生境界,从呵护人性的高度肯定闲居,否定出仕;白居易晚年闲居洛阳期间提出“中隐”说,追求“闲适”人生境界,悬置闲居与入仕价值高下的判断,实际是将闲居与入仕等而视之;邵雍绝意科举后迁居洛阳,标举“安乐”人生境界,重建闲居的价值,赋予其道德实践的意义而与入仕相抗衡。他们都致力于建构闲居期间日常生活的价值,努力实现士不遇焦虑的消解和现世性的精神超越。他们将屈原的凤凰和凡鸟对立与错位的士不遇书写模式加以转换,用来书写士不遇焦虑的调适及人生境界和自我形象。嵇康以挣脱网罗、远翔区外的鸾凤作为自我形象的隐喻;白居易将凤凰和凡鸟的对立与错位置换成凤与鱼的飞沉异势,并以“潜鱼”作为自我形象的隐喻;邵雍表达其本体论和人格论时,采用了凤凰与凡鸟的对立错位,其自我形象的建构主要通过观物所得及物我关系体认来实现。
