The benign interaction between technological innovation, industrial structure, and ecological environment optimization is important for the sustainable development of China’s economy. Based on panel data from 30 provinces (municipalities) in China from 2003 to 2019, a coupling coordination degree (CCD) model was adopted to evaluate the coordinated development level of the technological innovation-industrial structure-ecological environment system (TIE). Fixed-effect models were used to explore the subsystem impact on the coupling coordination level. A fully modified least-squares (FMOLS) method was used to analyze TIE subsystem interactions. The results show the following: (1) The coordinated development level of TIE has steadily improved. The CCD of the TIE was high in the east, flat in the center, and low in the west. (2) Subsystem development significantly and positively affected the degree of coupling coordination. The ecological environmental impact on the coordinated development level was the largest in the eastern regions and the influence of technological innovation on the coordinated development level was the largest in the central and western regions. (3) Industrial advancement had a positive impact on technological innovation in 30 provinces as a whole, and in the eastern, central, and western regions. A “U”-shaped relationship was found between technological innovation and industrial advancement in all 30 provinces, and in the eastern, central provinces. Industrial rationalization, industrial advancement, and technological innovation can promote the improvement of the ecological environment in all 30 provinces, and the eastern, central, and western regions.

The construction industry has great potential for carbon emission reduction, which strongly impacts the peak of carbon emissions and carbon neutrality. This paper compares foreign and Chinese articles on building carbon emissions from publication objects, journals, subject categories, authors, and institutions. It discusses the differences in research trends and hotspots from keywords, reference co-citation analysis, and historical citation analysis. The results show that the number of publications on building carbon emissions steadily increased. The research on building carbon emissions in foreign articles is earlier and more systematic than that in China, and the output and influence of foreign articles are generally more prominent than those of Chinese articles. However, the production and influence of articles by certain Chinese authors and institutions have been remarkable. The topics of ‘CO2 emission’, ‘life-cycle assessment’, ‘environmental impact’, ‘greenhouse gas emission’, and ‘renewable energy’ are essential subjects for foreign and Chinese articles in the research field of building carbon emissions and the development trend is similar. The thematic direction of Chinese articles is more divergent and lacks well-developed themes that greatly influence other research themes. Finally, based on the research results, this study puts forward the potential future research direction of building carbon emissions. The results of this study will provide a current and systematic overview of this field, which will be helpful for future researchers to promote the development of research on building carbon emissions.
