Description:

The transportation sector has significantly contributed to greenhouse gas and air pollutant emissions. Based on the Kaya constant equation and the LMDI decomposition model, A synergistic reduction effect model of transportation tailpipe Environmental negative externalities emissions is constructed to adopt the inter-provincial panel data of China from 2005 to 2019. The synergistic reduction emission impact and indirect drivers between air pollution and carbon emission are analyzed. The results show that the drivers of the synergistic impact are mainly energy efficiency and industrial structure. Significant synergistic emission reduction effects exist in eastern China, western China, medium-sized transportation markets, and less developed tourism regions. Further, increasing environmental regulation can improve the synergistic reduction impact of the transportation sector's air pollutants and carbon emissions. This paper provides theoretical support for winning the battle of pollution prevention and control and achieving the "dual carbon" goal in the new era.

Large amounts of fossil fuels that are consumed in association with the urbanization process, lead to billions of tons of greenhouse gases and air pollutants. Air pollution control policies have the synergic effects on carbon emissions reduction, but whether they can improve the synergic emission reduction efficiency (SERE) needs to be studied. 279 Chinese cities are selected as research samples. We evaluate the synergic effect of China's “Air Pollution Prevention and Control Action Plan” (APPCAP) from the perspectives of benefits and efficiency with the Difference-in-differences (DID) model. We further decompose the SERE into synergic emission reduction technological efficiency change (SEREEC) and synergic emission reduction technological change (SERETC) to analyze the internal impact mechanisms. The result shows that: (1) SERE has increased by 8 % from 2010 to 2017, for the expansion of the possibility boundary. (2) The APPCAP has co-benefit of carbon emissions reduction by 1.5 %, but inhibits the SERE increase by 1.2 % because of the lack of resource allocation efficiency improvement. (3) The APPCAP has an inhibitory effect on SEREEC and a promoting effect on SERETC. Therefore, the government should emphasize the source control and treatment efficiency, and further strengthen the system innovation for achieving urban sustainable development effectively.

Family firms often face trade-offs between economic and non-economic objectives when making decisions on the pollution prevention strategy, one type of proactive environmental strategy. Existing evidence from developed economies has largely shown a positive relationship between family firms and pollution prevention strategy, but little research has investigated whether there is a positive relationship in emerging economies as well. This research adopts agency and institutional theories to examine the impact of family firms on pollution prevention strategy in the context of China. We analyzed a sample of 2348 Chinese firms using ordinal least squares regression. Empirical results show that family firms underinvest in pollution prevention strategy relative to non-family firms, particularly when the Chief Executive Officer (CEO) is not the firm’s founder. Moreover, different types of institutional factors alter the effect in different ways. Regulatory pressure weakens the negative effect of family ownership on pollution prevention strategy, whereas institutional support strengthens this main effect. These findings enrich the understanding of why and under what conditions family firms perform pollution prevention strategy.
