中国展览业发展基于区域经济发展的空间分布特征，显示出展览业与区域经济的空间相关与溢出效应，并由省域层面展览业的部门结构特征展现出区域专业化水平。本研究从行业分布视角，以2019年会展行业数据的比较，揭示中国省域展览业的行业结构特征及其空间差异化格局，并以行业集中分布指数、区位熵指数与地区相对专业化指数，描绘中国省域展览业行业部门分布集中程度；结果发现当前中国省域展览业行业部门分布集中程度差异明显。中西部地带行业部门结构明显优于东部；全国展览业在不同行业部门的区位熵呈现递增规律，省域展览业在不同行业部门与地区的专业化程度存在明显差异，而地区生产总值与展览业行业部门分布集中程度的相关性亦大不相同，优化行业部门结构及其空间布局以推动会展内涵，需依据区域传统产业模式才能确实发挥展览优势。

The development of China's exhibition industry is based on the spatial distribution characteristics of regional economic development, which shows the correlation and spillover effect between the exhibition industry and regional economic. The level of regional specialization begins from the industrial structure characteristic to the provincial integration. This study reveals the characteristics of the industry structure and spatial differentiation pattern of China's provincial exhibition industry from the perspective of industry distribution using 2019 exhibition data, and finds that the current distribution of the industry sector is obviously different. The structure of the industry sector in the central and western regions is superior to the eastern part. The entropy of the national exhibition industry in different industrial sectors shows increasing law, and the degree of specialization of the provincial exhibition industry in different sectors and regions prevails. The correlations between regional GDP and the concentration of the distribution of the exhibition industry sector are diverse. Optimization of industrial structures and the spatial distributions is necessary to promote the content upgrading of exhibition according to traditional advantages of local industries.
