The links among firms’ environmental regulation, innovation process, and sustainable development has been analyzed, but a research gap still remains in terms of environmental commitment and different types of sustainable innovation in firms’ sustainability. Through collecting a dataset of 380 valid respondents from Chinese manufacturing firms, this paper incorporates evironmental regulation, environmental commitment, sustainability exploration innovation, sustainability exploitation innovation, environmental performance, and business performance into a multiple mediating effect model. Our key emperical findings are as follows: (1) Environmental regulation not only cannot affect environmental performance and business performance, but also cannot affect the two types of firm performance through sustainability exploration innovation or sustainability exploitation innovation; (2) The relationship between environmental regulation, environmental performance (or business performance) is subsequently mediated by both environmental commitment and sustainability exploitation innovation; (3) Environmental regulation does not affect environmental performance (or business performance) through environmental commitment and sustainability exploration innovation. These results do, however, support the Porter Hypothesis in terms of revealing a new multiple mediating effect path dominated by environmental commitment and sustainability exploitation innovation. Our findings can provide a better understanding of how environmental commitment and sustainability exploitation innovation play a key effect in helping firms relieve the pressure from environmental regulation, and thus improve their environmental management while keeping their competitive edge.

Public health issues are a global focus, but recent research on the links between fossil energy consumption, pollutant emissions, and public health in different regions have presented inconsistent conclusions. In order to quantify the effect of fossil energy use and pollutant emissions on public health from the global perspective, this paper investigates 33 countries with high GDP and fossil energy consumption from 1995 to 2015 using a fixed effect model. Further, this paper utilizes heterogeneity analysis to characterize the disparity of countries with different features. Empirical results indicate that total fossil energy consumption is beneficial to the life expectancy of the population (LEP), but pollutant emissions (PM10 concentration and greenhouse gas scale) have a negative effect on LEP. Moreover, the heterogeneity test indicates that pollutant emissions lowers LEP in net energy importers more than in net energy exporters, and the effect of such emissions in low- and middle-income countries on public health is more harmful than that in high-income countries. These findings suggest that it is a greater priority for governments to strengthen the control of pollutant emissions through enhancing the efficiency of energy consumption, rather than by reducing its scale of use in low- and middle-income, and net energy importing countries. Additionally, governments also need to focus on the volatility of pollutant emissions in high-income countries with necessary control measures.

With the acquisition of sustainable development, pursuing the coordinated development of social economy and ecological environment has been a critical approach of Northeastern China. Since the reform and opening‐up, marketization has profoundly affected the regional social economy. However, what role will marketization play in regional sustainable development? Can marketization improve sustainable development measured by the coupling coordination degree? This paper adopts the coupling coordination degree model (CCDM) to estimate the coupling coordination degree and further explore the impact of marketization on the coupling coordination degree in Northeastern China from 1994 to 2019. The results show that the average values of the static coupling degree (SCD), dynamic coupling degree (DCD), and coupling coordination degree (CCD) remained in a tiny coordinated state, which indicated that the level of sustainable development in Northeastern China is presented still primary from 1990 to 2019. Marketization has a significant negative impact on the coupling coordination degree, which indicates that marketization should be considered in the process of sustainable development in Northeastern China.

The identification of the metro’s centrality advantage stations and regions is of great significance for in-depth understanding of the centrality layout of existing urban areas. This study selects all stations of the Hangzhou Metro Planning (2005-2022) as research cases. Based on the centrality of the complex network, it will study the spatial distribution characteristics of centrality advantage stations. The study found that: subway stations at each stage can be classified into four types of centrality advantages, and there are significant differences between these types, with a significance of 0.000; at the same time, the Type 1 and Type 2 of stations establish the core framework of the centrality advantages area; the gathering hot spot roughly establishes the range of the centrality advantage area distribution, which defines the boundary of the high advantage area. The transportation network advantage of the centrality advantage stations will be transformed into the TOD development advantage and potential of its surrounding area.
