“…However, building density, land nature mix, green area, water area, railway length, and land patch scale did not affect carbon emissions per unit of GDP. Green land, considered significant in some studies 25 , does not show significance in this study, which may be related to the size and degree of development of the city, and presumably because its effect has been captured by the other variables.…”

“…In existing studies, several studies have pointed out that urban density 12,[20][21][22] , functional mix 23 , land use type 24,25 , and traffic structure 10,26 have an impact on the carbon emissions efficiency of cities. Since the scale of this study is within a single city, which is relatively smaller, the study combines 5Ds built environment elements raised by Ewing 27 to refine the elements for the above four categories, resulting in the 14 elements from four Modeling the relationship between multilevel spatial structure elements and carbon emission efficiency.…”

Quantitative research on the impact weight and impact of regional heterogeneity of urban spatial structure elements on carbon emissions efficiency can provide a scientific basis and practical guidance for low-carbon and sustainable urban development. This study uses the megacity of Chengdu as an example to measure and analyze the spatial carbon emission efficiency and multidimensional spatial structure elements by building a high-resolution grid and identifying the main spatial structure elements that affect urban carbon emissions and their impact weights via the Ordinary Least Squares regression (OLS) and Geographically Weighted Regression (GWR). The spatial heterogeneity of the impact of each element is also explored. The results show that the overall carbon emission efficiency of Chengdu is high in the center and low on the sides, which is related to urban density, functional mix, land use, and traffic structure. However, the influence of each spatial structure element is different in the developed central areas, developing areas of the plain, mountainous developing areas, underdeveloped areas of the plain, and mountainous underdeveloped areas. Thus, it is appropriate to form differentiated urban planning strategies based on the characteristics of the development of each zone. The findings provide inspiration and a scientific basis for formulating policies and practice to the future low-carbon development of Chengdu, while provide a reference for other growing megacities.

“…At the economic and social levels, scholars have tried to explore the impact of land use on carbon emissions from the perspectives of land use intensification [32,33], land expansion [34,35], land layout [36,37], the structure and intensity of land use [38,39], and land urbanization [40,41]. Governmental land transfer is the main form of land use and development in China, and can be used to produce "land finance".…”

With the implementation of deep-market-oriented reforms in China, an accurate interpretation of the effect and transmission mechanism of the marketization of industrial land transfer on carbon emission reduction can provide references for further elevating the role of land policy in China’s low-carbon economic transition. Based on the balanced panel data of China’s provincial level from 2009 to 2020, this paper uses carbon emission intensity to quantify emission reduction targets, and studies the effects of the marketization of industrial land transfer on regional carbon emission intensity, as well as its internal mechanism, by describing the typical characteristics. Moreover, this paper analyzes the moderating role of environmental governance and conducts area heterogeneity analysis. The main results show that (1) the marketization of industrial land transfer can significantly reduce regional carbon emission intensity, and the negative effect is stronger in the mid-west compared with the effect in the east. (2) Environmental governance can play a positive moderating role in the relationship between the marketization of industrial land transfer and the carbon emission intensity. (3) Industry selection is the internal mechanism by which the effect of the marketization of industrial land transfer on regional carbon emission intensity operates, and the mechanism is represented more prominently in the mid-west. The main conclusions provide inspiration for land policy regulation in relation to carbon emission reduction. China’s local governments should implement specific strategies to improve the market-based operation mechanism of land, attracting industries with high energy efficiency and low carbon emissions, and strengthening the intensity of environmental governance.

“…With the frequent occurrence of extreme natural disasters around the world, climate change caused by excessive CO 2 emissions has severely hindered the sustainable development of mankind and threatened ecosystems and biodiversity (Aldieri and Vinci, 2020;Hao and Li, 2020). In order to realize the sustainable development of mankind, the governments call for energy conservation and emission reduction, the implementation of carbon policies (carbon tax, carbon subsidies, carbon emission trading mechanism), and the development of a low carbon (LC) economy with practical actions (Wang et al, 2016). Some countries have set carbon peak and carbon neutral targets.…”

Knowledge sharing (KS) in the green supply chain (GSC) is jointly determined by the KS efforts of suppliers and manufacturers. This study uses the differential game method to explore the dynamic strategy of KS and the benefits of emission reduction in the process of low carbon (LC) technology in the GSC. The optimal trajectory of the knowledge stock and emission reduction benefits of suppliers and manufacturers under different strategies are obtained. The validity of the model and the results are verified by numerical simulation analysis, and the sensitivity analysis of the main parameters in the case of collaborative sharing is carried out. The results show that in the case of centralized decision-making, the KS efforts of suppliers and manufacturers are the highest, and the knowledge stock and emission reduction benefits of GSC are also the best. The cost-sharing mechanism can realize the Pareto improvement of GSC’s knowledge stock and emission reduction benefits, but the cost-sharing mechanism can only increase the supplier’s KS effort level. In addition, this study found that the price of carbon trading and the rate of knowledge decay have a significant impact on KS. The study provides a theoretical basis for promoting KS in the GSC and LC technology innovation.
