北京市展览业时空分异特征

The Spatio-temporal Distribution of Beijing exhibition industry

展览业凭借强大的产业关联性和对经济发展的推动力,在推动现代服务经济的进程中,扮演着重要角色.北京作为我国展览业最发达的城市之一,其展览业在时空分布上初步形成了一定的规律.本文采用统计数据结合网页内容分析方法,建立2009～2012年北京市展览业信息数据库,并采用季节强度指数和空间Kernel分析法,对2009～2012年北京市展览业时空分布特点进行初步探讨,结果表明：①展览业具有明显的淡旺季,但淡季和旺季的差距呈缩小趋势.②不同类型制造业展淡旺季特征明显,但季节集中性随时间变化差异大.③展览业总体上集中在市区四环以内分布,空间分布呈单核心结构.④2009 ～2012年,展览业向市区四环内集中分布趋势更加明显,并向五环以外扩散.

Exhibition industry plays an increasingly important role on promoting the modem service economic development by virtue of its strong industry relevancy and huge role in promoting economic and social development.Beijing as one of the most developed cities in exhibition industry,initially formed certain rules and characteristics in spatial and temporal distribution.This article statistics the information data of exhibition industry in Beijing from year 2009 to 2012 based on statistical data and web content,and make preliminary research of spatial and temporal distribution of exhibition industry in Beijing from year 2009 to 2012 using index of Geographic Concentration and seasonal intensity and kernel spatial analysis method,the results show that,①Exhibition industry has obvious seasonal concentration,but the gap is narrowing between off-season and midseason; ②The manufacturing exhibitions have obvious seasonal concentration,but the seasonal concentration is difference over time;③Exhibition industry concentrate in urban area within the fourth ring road,and shows a single core structure in spatial distribution.④Form year 2009 to 2012,the trend is more apparent that exhibition industry concentrated in urban area within the fourth ring road,at the same time,exhibition is diffusion to outside fifth rings.The spatial distribution regularity of different exhibition industries is not obvious.This research could provide a reference for the organization management and marketing of the Beijing exhibition industry.
