The digital economy (DE) and real (RE) are dual pillars of the modern economic system. deep integration (IDR) has emerged as a pivotal strategic trend. IDR not only can enhance international competitiveness but also contributes to sustainable development goals. This work collects DE RE data from 30 provinces in China between 2012 2022. entropy weight method coupling coordination degree (CCD) model employed measure level IDR. Furthermore, Dagum Gini coefficient, Kernel density estimation, spatial autocorrelation model, geographically temporally weighted regression (GTWR) utilized analyze spatial–temporal evolution influencing factors CCD. following conclusions drawn: (1) During study period, CCD shows an upward trend, value is relatively low. (2) There significant differences CCD, inter-regional difference primary cause. (3) regional continuously widening. (4) obvious global agglomeration feature, been enhanced (5) policy intensity, infrastructure, industrial structure, human capital, technological innovation, market environment have impacts on obtained findings provide important theoretical support for coordinated RE.

In a construction industry characterized by rapid change and increasing complexity, traditional labor-intensive methods of structural safety inspection suffer from numerous limitations, including low productivity, extended project duration, high costs. Accuracy speed are particularly vital for diagnosis in older structures, fire-damaged buildings, large-scale facilities, yet conventional heavily rely on human expertise, leading to variability potential unreliability results. This study quantitatively assessed the productivity improvements economic benefits integrating terrestrial laser scanning (TLS) building information modeling (BIM) into assessment process. Both visual TLS-based approach were treated as production systems, queueing theory was employed analyze waiting times, service rates, The analysis three real-world projects revealed that 3D reverse method reduces total costs—including survey labor input, well costs—by about 80–89% compared method. Additionally, return investment (ROI) at level varies approximately 12% 136%, when applied multiple company level, overall ROI reaches 162%, demonstrating long-term adopting digital technology. These findings suggest TLS-3D has substantial terms gains impact.
