| New quality productivity is an advanced form of productivity that integrates data elements, intelligent technology, and institutional innovation, greatly improving the efficiency of production factor allocation and constructing various technological application scenarios, which can provide core impetus for the digital intelligence of the exhibition industry. The exhibition industry serves as a platform that connects market production and consumption, supply and demand. It not only promotes exchanges among enterprises at the technical and information levels, forces internal industrial upgrading within enterprises, but also significantly boosts trade between China and the world, enhancing China's international economic status. However, the bottlenecks such as low operational efficiency and single scenarios in the traditional exhibition industry are difficult to keep pace with the development of the digital age. Therefore, it is urgent to introduce new quality productive forces into the exhibition field. By leveraging their advantages of data-driven and technological innovation, these forces can solve the obstacles in the digital intelligence of the exhibition industry. Based on the national city-level panel data from 2020 to 2024, this paper mainly quantifies the mediating effects of technological innovation and business model innovation through the construction of structural equation models and regression analysis. It also introduces the government support intensity as a moderating variable to systematically verify the relationships and influence degrees among the variables. This research method ensures the statistical scientific of the study and provides favorable data support for revealing the impact of new quality productivity on the digital intelligence of the exhibition industry. The results showed that: (1) the development of new quality productivity forces have a significant promoting effect on the digital intelligence of the exhibition industry. (2) New quality productivity forces promote this transformation through two paths: technological innovation and business model innovation. Between them, technological innovation contributes more, while business model innovation plays a relatively small mediating role. (3) The government's support plays a positive regulatory role in this transformation process. Therefore, it is necessary to further integrate into the digital economy and promote the digital intelligence of urban exhibitions; We need to strengthen talent support and cultivate exhibition talents equipped with both digital literacy and professional expertise; We need to strengthen the concept of low-carbon environmental protection and create a green city exhibition ecology. Through these measures, the institutional and technological dividends of new quality productivity can be further released, facilitating the high-quality development of the exhibition industry. |
