“…However, the quadratic coefficients of the technological innovation of the transportation industry in most regions is negative, and the coefficient in the western region is lower than that in the eastern region, showing an obvious "inverted U-shaped" relationship between the technological innovation and the carbon emissions of the transportation industry, and when it breaks through the technical pain points, this carbon reduction effect is more effective in the western region than in the eastern region. This result indicates an "inverted U-shaped" relationship between the number of patents and carbon dioxide emissions [52]. The impact of increased innovation capabilities on carbon dioxide emissions differs in different regions: some regions are n-shaped, while others have U-shaped associations [53].…”

“…Secondly, it is important to promote the low-carbon transformation of the transportation industry with technological innovation. The impact of transportation technology on transportation carbon emissions presents an "inverted U-shaped" relationship, showing that it is necessary to break through the initial stage of the slow effect of transportation technology development on carbon emissions, and insist on long-term support for transportation research [52]. In terms of the government's top-level design, a comprehensive development plan for technological innovation in the transportation industry should be formulated, the long-term and basic nature of technological innovation should be highlighted, and long-term planning and investment in technological innovation in the transportation industry should be focused on.…”

The carbon reduction effect of technological innovation in the transportation industry is conducive to China’s anticipated realization of carbon neutrality. Therefore, we evaluated carbon emission reduction effect of technological innovation in the transportation industry in China. Based on the panel data of 30 sample provinces in China (excluding Hong Kong, Macao, Taiwan and Tibet) from 2012 to 2018, using the Moran’I index and Getis-Ord Gi index, this paper analyzes the evolutionary trend and spatial autocorrelation of carbon emission in the transportation industry, and analyzes the impact of technological innovation on carbon emission levels of the transportation industry and its spatiotemporal differences by using the geographical and temporal weighted regression (GTWR) model by using ArcGIS 10.4 software. The conclusions are as follows: The carbon emission level of China’s transportation industry generally has been rising steadily, showing a spatial distribution pattern of high emissions in the east and low emissions in the west. The cold spots are concentrated in the western region, and the hot spots are situated in the central and eastern regions. Technological innovation has a carbon reduction effect on the transportation industry in the eastern and north-eastern regions, while the effect in other regions is not obvious. However, there is an obvious “inverted U-shaped” relationship between technological innovation and the transportation industry’s carbon emissions. The technological innovation in the transportation industry will have a significant carbon reduction effect after breaking through the technical pain points. This carbon reduction effect has a higher effect on the western region than on the eastern region. In addition, the economic development level, the fiscal expenditure proportion of the transportation industry, the higher education level, and the proportion of fixed asset investment in the transportation industry have played a positive role in reducing carbon in the transportation industry, but the spatial heterogeneity of this carbon reduction effect is relatively strong. Therefore, during the “14th Five-Year Plan” development period in China, it is necessary to continuously promote the low-carbon development of the transportation industry with technological innovation, while highlighting the differentiated carbon reduction governance, and consolidating the role of talents and fiscal support.

“…An important factor leading to climate change is the emission of greenhouse gases [ 8 , 29 ], and carbon dioxide is a major component of greenhouse gases, so current concerns about carbon emissions has become a hot topic of scholars [ 28 , 30 , 31 , 32 ]. As the world’s largest carbon dioxide emitter [ 10 , 12 ], China contributed an average of 63.9% of the increase in global emissions from 2006 to 2016 [ 12 ]. As a responsible major country, China proposed that it should reach the peak of CDE by 2030 and achieve the strategic goal of carbon neutrality by 2060 [ 33 ].…”

“…Carbon dioxide emissions (CDE) are a key factor in climate deterioration [ 8 , 9 ]. China, as the largest CDE producer in the world and one of the countries committed to achieving carbon neutrality and complete elimination of carbon emissions by 2060 [ 10 ], is under tremendous pressure to reduce emissions [ 10 , 11 , 12 ]. In order to curb the increase of CDE, the Chinese government has made a series of commitments and plans to promote a comprehensive shift in socio-economic development to a green development model, starting from 2021 [ 13 ].…”

The Paris agreement is a unified arrangement for the global response to climate change and entered into force on 4 November 2016. Its long-term goal is to hold the global average temperature rise well below 2 °C. China is committed to achieving carbon neutrality by 2060 through various measures, one of which is green technology innovation (GTI). This paper aims to analyze the levels of GTI in 30 provinces in mainland China between 2001 and 2019. It uses the spatial econometric models and panel threshold models along with the slack based measure (SBM) and Global Malmquist-Luenberger (GML) index to analyze the spatial spillover and nonlinear effects of GTI on regional carbon emissions. The results show that GTI achieves growth every year, but the innovation efficiency was low. China’s total carbon dioxide emissions were increasing at a marginal rate, but the carbon emission intensity was declining year by year. Carbon emissions were spatially correlated and show significant positive agglomeration characteristics. The spatial spillover of GTI plays an important role in reducing carbon dioxide emissions. In the underdeveloped regions in China, this emission reduction effect was even more significant.

“…On one hand, the R&D input of companies can directly affect company operating income [27,28]. On the other hand, the R&D input of companies may also have an impact on their patent performance [29]. This impact runs through the entire process, from increasing R&D input to improving company operating income.…”

The Chinese government is actively promoting green and low-carbon transformation for economic and social development, especially in the wastewater treatment industry. This article uses regression analysis to study the impact of company R&D input on patent performance and company operating income for different regulatory environments and regions. Companies in the wastewater treatment industries of the Shanghai and Shenzhen stock exchanges from 2013 to 2020 are selected as research samples. The results show that there is a partial mediating effect of patent performance between company R&D input and company operating income; the stimulative effect of company R&D input is strongest in a high external-high internal environment; this stimulative effect is also more significant in the three strategic regions when compared with other regions. The findings suggest that company R&D input can promote company operating income. Thus, wastewater treatment enterprises should establish complete R&D systems to improve their innovative output capabilities. Enterprises in more developed regions should play a leading role in undertaking technological innovation. Furthermore, the government should formulate policies to improve the capacity of companies to conduct wastewater treatment and continue down the road of green development.
