城市韧性对旅游经济的空间溢出效应研究——以长三角城市群为例

城市为旅游发展提供支撑,其韧性水平对区域旅游发展具有重要的影响。论文利用长三角城市群各地区2004—2018年的面板数据,在定量测算城市韧性的基础上,借助空间面板杜宾模型揭示城市韧性对旅游经济的空间溢出效应。结果显示：长三角各地区城市韧性水平空间差异显著,但总体上韧性水平呈现上升趋势。城市韧性与旅游经济之间存在较强的空间相关性,城市韧性对旅游经济具有显著的空间溢出效应(ρ=0.444,P<0.01)。其中,城市经济韧性和城市生态韧性对旅游经济具有正向溢出效应,城市社会韧性和城市工程韧性对旅游经济具有负向溢出效应。未来城市旅游发展需要关注城市韧性水平,注重城市韧性的空间溢出效应,避免虹吸效应,同时还需要加强长三角城市群区域间交流合作,促进旅游经济高质量发展。     

Carrying Capacity of Marine Region in Liaoning Province

Carrying capacity is one of important studies on coordinating development of population,resources,and environment.At present,the researches on it mainly concentrate on the carrying capacity for population and economy,such as the water resources carrying capacity,the land resources carrying capacity,the environment carrying capacity,etc.Based on the related theories and methods,this paper creatively proposed the concept and meaning of carrying capacity of marine region,and formed the appraisal system.According to the developing situation of marine economy of Liaoning Province in recent years,and by employing the method of the state space,this paper also measured the carrying capacity and carrying state of marine region and discussed the sustainable problems of marine economy of Liaoning.The research results show that the carrying state of marine region of Liaoning is in the state of overloading at present,but taking a favorable turn.     

Cleantech clusters: Transformational assemblages for a just,green economy or just business as usual?

The rhetorical zeal for green enterprise as a global fix for the tripartite challenges of economic recession, environmental degradation and social inequality is increasingly visible in state and non-state pronouncements around the globe under the banner of ‘The Green Economy’. In particular, many policy-facing statements call for transitions leading to a transformation in development practices. Yet there is little detail either in policy or research regarding the types of transitions needed and how they are to be initiated, nor agreement about what a transformed economy might look like. Despite this, there are emergent activities within the cleantech arena which are being heralded as actually existing examples of green economy activities. One means through which these activities are seeking to exert influence over development trajectories is by clustering both at the subnational and transnational level. While diverse in formation, many of these clusters are hybridised, involving actors from public, private and civil society sectors. Critiquing the efficacy of mainstream industrial cluster theory to analyse hybridised cleantech clustering, this paper presents a unique synthesis of current thought on multiscalar environmental governance and socio-spatial formations to explore the practices and potentialities of these hybridised cleantech clusters. Surveying the landscape of cleantech clustering and meta-clustering, before focusing in depth on one case study, the contribution of clustering to transitioning towards a transformed green economy is considered. Despite strong forces, both within and beyond cleantech clusters, for maintaining neoliberalised approaches to cleantech activity, it is concluded that for as long as cleantech clusters remain open and inclusive of actors proposing alternative pathways they do represent potential, albeit provisional, assemblages for transformation.

Nonlinear regional economic dynamics: continuous-time specification,estimation and stability analysis

This paper presents an innovative approach to the study of regional economic dynamics within a nonlinear continuous-time econometric framework—a generalized specification of the Lotka–Volterra system of equations. This specification, which accounts for interdependent behavior of three industrial sectors and spillover effects of activities in neighboring regions, is employed in an analysis of five Italian regions between 1980 and 2003. For these regions, we report estimation results, characterize the varying systems dynamics, analyze the models’ local and global stability properties, and determine via sensitivity analyses which structural features appear to exert the greatest influence on these properties.

Characteristics and variation law of wind-blown sand delivered to the Ningxia-Inner Mongolia reach of the Yellow River under a changing environment

Wind-blown sand is one of the key factors affecting the evolution of sediment transport,erosion,and deposition in rivers crossing desert areas.However,the differences and complex variations in the spatial and temporal distribution of the underlying surface conditions are seldom considered in research on the river inflow of wind-blown sand over a long time period.The Yellow River contains a large amount of sediment.The Ningxia-Inner Mongolia reach of the Yellow River was selected as the research ...     

基于生命周期评价的铜尾渣资源化利用环境效益——以制取蒸压砖为例

我国每年产生的铜尾渣超过1 500万吨,持续堆存会造成严重的环境危害,而资源化处理则通常能够充分利用铜渣当中的资源并一定程度上降低环境危害。通过生命周期评价方法,对铜尾渣资源化利用制取蒸压砖并副产铜精矿、铁精矿和重介质的工艺过程的环境影响进行了分析。结果表明,该技术方案最主要的环境影响为人体毒性(33 886 kg 1,4-二氯苯当量 /资源化1 000吨铜尾渣);水泥生产阶段环境负荷最高,在7种环境影响类别中均有最高的贡献;贡献最明显的关键物质为氮氧化物,其对富营养化、酸化、光化学污染贡献占比分别为94.1%、42.0%和24.3%。将生产蒸压砖和副产的铜精矿、铁精矿、重介质所避免的环境影响纳入考虑范围之后,发现该铜尾渣资源化方案能够取得明显的环境效益。
