Evaluation of the Vitality of Industrial Heritage Renewal at Zhengzhou Oil Refinery Through Installation Art Integration

Against the backdrop of industrial heritage conservation and reuse， the revitalisation of spatial vitality has emerged as a crucial pathway for the transformation and renewal of industrial heritage sites. Taking the industrial heritage of Zhengzhou Oil Refinery as a case study， this research adopts installation art as the starting point for vitality activation. By constructing a “cognitive-spatial-environmental” dimensional framework and employing grey relational analysis to identify the correlation between spatial vitality elements and spatial activation， it reveals the mechanism through which the integration of installation art contributes to the formation of public spatial vitality within industrial heritage sites. Findings indicate： within the cognitive dimension， functional requirements exhibit the highest correlation （0.708）， demonstrating that the thematic distinctiveness and expressive form of installation art significantly enhance public recognition and emotional engagement. Within the spatial dimension， functional requirements also show the strongest correlation （0.892）， indicating that the layout and functional design of installation art decisively influence spatial order and crowd aggregation. Within the environmental dimension， functional requirements showed high correlations with spatial organisation （0.777） and activity facilities （0.733）， while activity facilities had the lowest correlation （0.202）. This indicates that the functionality and layout of installation art significantly drive environmental vitality， with facility enhancement serving as a supplementary optimisation.
