资源型城市构建和谐社会探析

我国许多城市属于资源型城市，以不可再生资源为基础的资源型产业在城市经济中占主导地位。当前，随着资源的枯竭，这些城市面临着许多经济和社会问题。对于这些衰退的资源型城市构建和谐社会就显得尤为重要。本文经过分析指出资源型城市构建和谐社会的根本在于可持续发展，并提出了相应的对策建议。     

湘东北都市带城镇体系的结构特征与优化思路

东北城市群专利资源布局的空间关联性——基于Moran指数的解释

在明确专利资源内涵和价值属性的基础上,分析了1992-2012年间专利资源在东北36个地级以上城市的空间分布格局及空间关联性,结果显示,东北各城市专利资源存量差异巨大,整体呈“东南强西北弱”的分布格局;增速相对较为均衡,呈现“沿海边界快、内陆慢”的分布格局。同时,东北各城市专利资源的空间布局表现出很强的地域固化性,多数城市专利资源基础薄弱。城市间空间联系松散,尚未形成专利的有效集聚。上述分布格局对东北加快落实创新驱动发展战略,主动适应新常态带来了负面影响。     

Fairytale authenticity: historic city tourism,Harry Potter,medievalism and the magical gaze

ABSTRACT

This article makes an original contribution to debates about authenticity by asking how tourist experiences of the medieval historic environment are linked to fairytales, providing a new way for tourists to imaginatively authenticate heritage. The architecture of some historic cities is preponderantly medieval, an era which is strongly associated with fairytales. Magical-historical double affectiveness has been compounded in the collective imagination by modern fairytales such as the fantasy Harry Potter and Game of Thrones which employ historic city locations and faux-medieval settings, establishing a fluid magi-heritage simulacrum. This is concretised by the appearance in many historic cities of evidence of magical placemaking and staged magical authenticity, such as wizarding shops. The study used a visual methodology to examine 14 historic cities including Oxford, Cambridge, Bath, York, and Canterbury, demonstrating how the magical gaze employs fairytale schemata to imaginatively authenticate places. The findings illustrated how heritage tourists serendipitously encountered the medieval-fairytalesque, unfolding the agency of monumental cathedrals and castles and discovering stories and the historicisation of mythology within the extraordinary-ordinary streetscape. The research findings imply that in an era when the fantasy genre is increasingly popular, the experiential authenticity of heritage tourists may be enhanced by the ‘heritage marvellous.’
