摘要
以长江经济带为研究案例,分别采用超效率SBM模型和熵值法对长江经济带旅游资源绿色利用效率和新型城镇化水平进行测度,并利用马尔科夫链揭示两者耦合协调发展的时空演变特征。结果显示:(1)2005—2017年长江经济带旅游资源绿色利用效率和新型城镇化水平呈波动上升的态势,但发展水平仍较低,2017年分别为0.885和0.493,提升空间较大。不同区域两者发展水平差异较大,面临着突出的发展不平衡问题。(2)研究期间长江经济带旅游资源绿色利用效率与新型城镇化耦合协调度呈现出波动增长的良好发展态势,其中,下游地区耦合协调度较高且变化态势相对平缓,年均增长率仅为1.28%,中、上游地区的耦合协调度较低但变化幅度相对较大,年均增长率分别达到3.29%和4.48%。(3)各地区耦合协调度空间分布区位差异明显,呈现出"下游—中游—上游"梯度递减的规律,且具有明显的空间集聚特征,其中,中、上游省区耦合协调类型空间演变较大,下游省区较稳定。(4)长江经济带旅游资源绿色利用效率与新型城镇化耦合协调度存在"俱乐部收敛"现象,具有维持原有状态的稳定性,且其动态演进是一个相对持续、渐进的过程,短期内难以实现跨越式发展。
Taking the Yangtze River Economic Belt as the research object, this paper measures the development level of green utilization efficiency of tourism resources and new urbanization in the Yangtze River Economic Belt from 2005 to2017 based on the super efficiency SBM model and entropy method. On this basis,the Markov chain is adopted to reveal the spatio-temporal evolution of their coupling coordinated development. The results show that: 1) The green utilization efficiency of tourism resources and new urbanization in the Yangtze River Economic Belt shows a fluctuating upward trend in 2005-2017, but their development level is still low, showing a large space for improvement and a prominent problem of unbalanced development. 2) During the study period, the coupling coordination degree between the green utilization efficiency of tourism resources and new-type urbanization in the Yangtze River Economic Belt presents a good development trend of fluctuation growth,what’s more,the coupling coordination degree in the downstream region is high and the change trend is relatively gentle, with an average annual growth rate of only 1.28%. While the coupling coordination degree in the middle and upstream regions is low but the change range is relatively large,with an average annual growth rate of 3.29% and 4.48% respectively. 3) The spatial distribution of coupling coordination degree has remarkable regional difference, showing a gradual decreasing rule from the lower reaches to the upper reaches,and has obvious spatial agglomeration characteristics. The spatial evolution of coupling coordination types is large in middle and upper reaches of Yangtze River Economic Belt, and is stable in lower reaches. 4) The phenomenon of "club convergence" exists in the coupling coordination degree between green utilization efficiency of tourism resources and new-type urbanization in the Yangtze River Economic Belt,which has the stability on maintaining the original state. Moreover,itsdynamic evolution is a relatively continuous and gradual pr
