Abstract
The implementation of the Standard for Bills of Quantities and Valuation for Construction Works (GB/T 50500-2024) effectively phases out fixed quota pricing and imposes elevated digital capability requirements on cost consulting enterprises, which acts as a core policy driver for the sustainable digital transformation of the built environment industry. However, the sector faces a prominent paradox: the technical merits of digital tools are widely recognized, yet on-site implementation remains stagnant.Based on the Technology Acceptance Model (TAM), this study collected 600 valid questionnaires from practitioners of Chinese cost consulting enterprises and constructed a structural equation model to examine the influence mechanism of technological relative advantage and technological compatibility on digital technology adoption intention. In this study, digital technology referred to a broad set of cost‑supporting tools including BIM, big data analysis, intelligent pricing algorithms and digital collaboration platforms. The empirical results showed that technological compatibility was the primary predictor of perceived ease of use (β=0.307). The direct effect of technological relative advantage on adoption intention was statistically insignificant, and its influence was fully mediated by perceived usefulness. This study clarified the cognitive transmission path from perceived technological advantages to adoption willingness, providing targeted countermeasures to advance the sustainable digital transition of cost management within the whole built environment industry.
