Taking regional airport in Henan Province and provincial airport group formed by Wuhan and Xi’an as the research object, the homogenization of regional airport development is studied. According to the characteristics of the airport, the form of the homogeneity of each dimension was deconstructed, the multi-dimensional index was established, and the homogeneity level of each characteristic index was measured. Taking four airport clusters in Henan as an example, the homogenization level was evaluated. According to the calculation results, ArcGIS software was used to draw the homogeneity level of regional airports in Henan Province. The findings reveal that Xinzheng Airport demonstrates high autonomy and international connectivity, whereas Nanyang and Luoyang airports, located in western and southern Henan, face issues of route similarity and identical airport positioning. Additionally, the close proximity between Nanyang and Xinyang airports hampers their expansion due to the limited scale of each city.Consequently, drawing from these outcomes, specific strategies for the coordinated development of Henan Province’s airports were proposed, in order to reduce homogenization according to airport positioning and urban development.

In order to achieve innovation-driven development, county is the bias and vitality, but which is difficulty. Based on the monitoring and evaluation data of science and technology innovation of counties in Hebei Province from 2020 to 2021, the spatial econometrics method was used to study the spatial distribution characteristics, spatial aggregation and spatial spillover effect of science and technology innovation. The results show that the northwest region of Hebei is the lagging cluster area of scientific and technological innovation, while the central and eastern region adjacent to Beijing and Tianjin is the developed cluster area, which presenting the spatial pattern of “collapse in the northwest and rise in the central and eastern regions”. From the perspective of spillover effect, county science and technology innovation-economic development, county science and technology innovation input-county science and technology innovation output have spatial spillover effect.

The implementation of the new urbanisation strategy promotes the construction of resilient cities, which is an important force to promote the sustainable development of the region. Based on the five dimensions of population development, economic development, social development, ecological development, and the development of residents’ life, an evaluation index system for the level of new urbanisation was constructed, and the time and space of the development level of new urbanisation of the Pearl River Delta were analyzed as an example. The time and space evolution characteristics of its new urbanisation development level were analyzed. The results showed that the development level of new urbanisation in the Pearl River Delta shows an upward trend from 2013 to 2022, but the development is unbalanced among cities. In time, the comprehensive score of new urbanisation in the Pearl River Delta rose year by year from 2013 to 2022, with the average annual score increasing from 0.354 to 0.498, and the growth rate of the development level fluctuating greatly. Spatially, the spatial changes in the level of new urbanisation in the Pearl River Delta in 2013, 2018 and 2022 are small, with large regional differences, showing a spatial pattern of slowing down from the central to the eastern and western regions.

High energy-consuming industries serve is a critical pillar of the national economy. Meanwhile, it is a primary source of energy consumption and environmental impact. Resource conservation and environmental protection have always been pivotal topics throughout China’s economic development process, playing a crucial role in advancing the sustainable development of Inner Mongolia’s energy bases. A theoretical framework for ecological efficiency within high energy-consuming industries in Inner Mongolia was constructed, and an ecological efficiency indicator system was established, in order to lay the groundwork for the transformation and development of Inner Mongolia’s high energy-consuming industries. The goal is to guide these industries toward more efficient resource utilization and environmentally friendly operations, thereby fostering a harmonious coexistence among the economy, society, and the environment in Inner Mongolia, and achieving sustainable development objectives.

Under the background of “dual carbon”, it is of great significance to comprehensively clarify the dynamic decoupling relationship between tourism carbon emissions and tourism economic development for the formulation of scientific tourism carbon emission reduction policies. The “bottom-up” tourism carbon emission measurement method was used to measure the tourism carbon emissions in Yunnan Province from 2010 to 2022, and on this basis, the Tapio decoupling model of tourism economy and tourism carbon emissions was constructed, and the decoupling relationship was analyzed. The results show that from 2010 to 2019, tourism revenue and tourism carbon emissions in Yunnan Province showed an upward trend, and in 2020, they decreased significantly, and from 2021 to 2022, Yunnan Province’s tourism revenue showed an upward trend, but the overall carbon emissions of tourism showed a downward trend, reflecting the low-carbon development of tourism in Yunnan Province. The contribution rate of tourism transportation carbon emissions to tourism carbon emissions in Yunnan Province is the largest, with an average proportion of 78% during the study period, and reducing tourism transportation carbon emissions is the key to low-carbon emission reduction of tourism in Yunnan Province. During the study period, the carbon emissions of tourism in Yunnan Province were mainly weakly decoupled, with high-quality strong decoupling in 2006 and 2022, and only in 2020, which generally reflected that Yunnan Province has achieved certain results in promoting energy conservation, emission reduction and low-carbon development of tourism.

The emergence of innovation research and development institutes is the product of China’s continuous improvement of innovation system construction under the background of implementing innovation-driven development strategy, which has played a huge role in promoting regional innovation cooperation and the transformation of scientific and technological achievements. Based on a total of 1 461 patents of 23 innovative R&D institutes in Tianjin, social network analysis was used to study the innovation cooperation of innovative R&D institutes and the transformation of scientific and technological achievements,. The results show that Tianjin has most independent R&D institutions, and the innovation ability gap between institutions is large.The innovation cooperation between institutions shows the characteristics of collectivization, and regional innovation cooperation needs to be improved. The conversion rate of scientific and technological achievements of institutions is much higher than that of general university research institutes. On this basis, targeted suggestions are put forward in order to provide reference for the government to formulate relevant policies.

Drawing upon Chinese A-share listed companies from 2009 to 2021 as research sample, the impact of digital transformation on firms’ sustained green innovation was explored. It is found that digital transformation significantly promotes firms’ sustained green innovation inputs and outputs, and this conclusion still holds after a series of robustness tests. Heterogeneity analyses results indicate that the contribution of digital transformation to firms’ sustained green innovation varies according to the nature of firms’ property rights and the type of industry. The role of information asymmetry, and investor focus in this relationship was further analyzed. The results show that information asymmetry partially mediates the effect of digital transformation on firms’ sustained green innovation, while investor focus play a moderating role.
