With the deepening of the "dual carbon" goal in China, green innovation plays an increasingly crucial role in promoting green and low-carbon development. The core purpose of green innovation is to promote the construction of ecological civilization, by reducing energy consumption, pollution emissions, and improving the ecological environment, thereby achieving harmonious coexistence between humans and nature. As a key component of the national innovation system, the enterprise innovation system plays a crucial role in enhancing the overall strength of China's green innovation. In 2011, the Ministry of Science and Technology of China, together with the People's Bank of China and other departments, launched the "pilot project to promote the integration of science and technology with finance". The pilot aims to lay a practical foundation for the comprehensive promotion of technology finance work, create policy space, and accelerate the construction of a diversified, multi-level, and multi-channel technology investment and financing system. Can the implementation of pilot policies combining technology and finance become a new engine to incentivize green innovation in Chinese enterprises? Can this policy provide diversified green funding channels for Chinese enterprises, thereby stimulating their vitality and enthusiasm for green innovation? This study regards the 2011 technology and finance integration pilot policy as a quasi-natural experiment and uses data from China's A-share listed companies from 2007 to 2022 to examine the policy's effects and mechanisms on Chinese corporate green innovation through a difference-in-differences method. The findings are as follows: First, the technology-finance integration pilot policy significantly promotes Chinese corporate green innovation, a conclusion that remains robust across a series of robustness checks. Second, environmental information disclosure plays a key moderating role between the policy and green innovation. Third, heterogeneity analysis reveals that the policy’s effects are more pronounced in state-owned, high-tech, and low-pollution of Chinese enterprises. This article confirms the positive role of technology finance in promoting green innovation in enterprises, providing strong theoretical and empirical support for the promotion of technology finance combined with policies.

The test result of mat concrete applying both hydration heat difference and insulation curing method on new construction of Cheongju university educational building are summarized as following. Both fresh concrete and compressive strength properties were satisfied In aimed value. Setting time of concrete incorporating 15% of fly ash(FA) retarded 1.2 hour than control concrete. Temperature history of mali concrete indicated that the highest temperature of center was exhibited at $126^{\circ}C$ after 51 hours while the highest temperature of upper section was $10.6^{\circ}C$ after 46 hours. Temperature Difference between center and surface was managed at less than $6^{\circ}C$ during whole curing period. In addition the temperature of upper section secured more than $3.3^{\circ}C$ while the temperature of outside was indicated at less than $-10^{\circ}C$. Maturity by parts of construction secured more than $30^{\circ}C$ DD higher than outside at 3 days. The more number of times, applying insulation curing method by double bubble sheets, increased, the higher economic effect was secured. Overall it was clear that applying both double bubble sheets and hydration heat difference method on this new construction can resist hydration heat crack, early frost demage and strength decrease. It also significantly contributed quality improvement of cold weather concreting
