This study investigates the ceiling maximum temperature distribution under various slope configurations when a fire source is located at the transition point of a Herringbone slope tunnel, with fire heat release rates of 10 MW, 20 MW and 30 MW. Results show that in the quasi-steady state, when the slope on the low-gradient side is 1%, the natural induced airflow velocity and fire environment are significantly influenced by the slope configurations on both sides of the transition point. Furthermore, the induced airflow velocity is directly proportional to the 0.1136th power of <i>Q*H*</i>. When the slope on the low-gradient side exceeds 3 %, the natural induced airflow velocity and fire environment are less affected by the slope composition on both sides. These findings provide a basis for optimizing ventilation and smoke exhaust design in Herringbone gradient tunnels.

This study proposes a blockchain-enhanced model to optimize inefficient accounts receivable financing in supply chains. It finds that with favorable conditions, blockchain can increase retailer orders and benefit upstream suppliers when coordinated with tailored contracts.

ABSTRACT Government subsidies are essential in guiding enterprises’ transformation and development. In the face of the green transformation dilemma for businesses during the transition from old to new growth drivers, it is crucial to investigate whether government subsidies can further enhance their effectiveness. We utilize a panel dataset of Chinese listed companies from 2007 to 2021 to explore the relationship between government subsidies and green innovation (GINN), with a specific focus on the moderating effect of marketization. We find that government subsidies not only significantly promote substantive green innovation (UGINN) and strategic green innovation (TGINN) but also improve business performance. The moderating effect model demonstrates the presence of market failure in GINN. We also show that marketization index (MI), environmental information disclosure (EDI), highly polluting industries (HPI), and manufacturing (MF) have significant moderating effects. The mechanism analysis further elucidates that government subsidies promote GINN by encouraging increased R&D investments. However, it is essential to note that these subsidies can also lead to inefficient investments by enterprises, resulting in a waste of resources. We offer significant enlightenment for understanding the government’s role in promoting GINN in enterprises and improving relevant subsidy policies.
