中文摘要：

以上海2 156家会展企业数据为基础,借助Arc GIS空间分析平台,研究了上海会展业时空演化过程,并从产业链角度探索会展企业的布局特征,最后探究其演化机理。结果发现：1）2000年以前上海会展业发展缓慢,空间分布差异逐渐减少;2002年之后,空间分布差异加大,集聚态势加强。2）1992年会展业主要集中在黄浦区和静安区,单中心集聚显著;2002年会展业沿黄浦江西岸逐向两侧延伸,形成以上海市政府为中心、徐家汇副中心为次核心的黄浦江西岸会展业发展轴;至2014年底呈现多中心集聚、多轴线扩展的网状分布格局。3）上海会展产业链均值中心主要分布在上海副中心城区徐汇区和中心城区黄浦区,空间分布上具有正的空间集聚现象,下游会展服务企业空间集聚态势更为明显。4）上海会展业空间格局的演化是区域发展战略和方针政策、城市交通和展馆设施、城市功能转型和产业结构调整、重大节事等各个要素共同作用的结果。

英文摘要：

The exhibition industry has become an important part of modern urban service economy. With the data of 2 156 exhibition companies in Shanghai, the authors use Arc GIS spatial analysis to study the temporal evolution of the process of Shanghai exhibition industry, explore layout features of exhibition business from the perspective of industry chain, and finally explore the evolution mechanism. The result shows that： 1） Shanghai exhibition industry developed slowly and the differences of the spatial distribution gradually reduced before 2000. After 2002, differences increased and gathering trend strengthened; 2） Exhibition industry was mainly distributed in Huangpu and Jing＇an Districts in 1992, single-center gathering was significant. In 2002 exhibition industry gathered along the west bank of the Huangpu River and gradually extended to both sides, forming an exhibition industry development axis where Shanghai government was the center and Xujiahui the sub-center. To the end of 2014, a multi-center cluster and expanded multi-axis network distribution pattern was presented; 3） The mean value center of Shanghai exhibition industry chain was located in Xuhui District, which is the sub-center of Shanghai, and Huangpu District, the downtown area of the city, its spatial distribution was of a positive spatial agglomeration. The space gathering trend of downstream exhibition services companies was more obvious; 4） The evolution of spatial pattern of Shanghai exhibition industry was influenced by many factors such as regional development strategies and policies, urban transport and exhibition facilities, transformation of urban functions and industrial restructuring, as well as major festival issues.
