Analysis on Energy Conservation and Emission Reduction Efficiency and Influencing Factors for Ports around Bohai in China under the Low Carbon Target

Abstract

The ports around Bohai in China were taken as the object of study in this research. In light of the panel data from 2014 to 2020, the super-efficiency SBM model was applied to measure and calculate the energy conservation and emission reduction efficiency of ports. In addition, the indicator system of influencing factors for energy conservation and emission reduction efficiency was constructed on the basis of the STIRPAT model, which provided a brand-new research perspective on environmental regulation, and the research method of ridge regression was applied for studying the influencing factors of energy conservation and emission reduction. The conclusion shows: except for the energy conservation and emission reduction efficiency of Qingdao port and Tianjin port reaching the significant degree, the energy conservation and emission reduction efficiency of other ports turned out to be invalid in the years of measurement, manifesting a relatively lower situation in the overall energy conservation and emission reduction efficiency for ports around Bohai; the major influencing factor for the energy conservation and emission reduction efficiency of the ports around Bohai is environmental regulation, which has played a prominent positive role; the technical factors also play an active role in enhancing energy conservation and emission reduction efficiency, and present a reversed tendency with resource endowment; the comprehensive economic strength can contribute to the efficiency of energy conservation and emission reduction of the ports.

Analysis of Carbon Emission Reduction at the Port of Integrated Logistics: The Port of Shanghai Case Study

“…Yuyan Zhou et al [34] used the WRF-CMAQ model to estimate the impact of port-related source emissions on air quality. Wang Shuang et al [9] used the super-efficiency SBM model to measure the energy-saving and emission-reduction efficiency of ports. In addition, based on the STIRPAT model, the influencing factors of energy savings and emission reduction efficiency were constructed for analysis.…”

“…Otherwise, shore power may be more attractive. Wang Shuang [9,16] and others found that environmental supervision is the main factor affecting the green energy saving efficiency of the Bohai Port Group, and technical factors also have a positive effect on energy saving and emission reduction in port groups. At the same time, the comprehensive economic strength has a positive effect on the improvement of the green energy efficiency of the port group.…”

“…In other variables, the factor will also be included in the final model results are shown in Figure 7. According to existing research [9], screen and ex (number of employees). Through a comprehensive analysis of the impact of th emissions of various indicators on the comprehensive logistics system of Shan Port, this article finally chose the container cargo throughput (P1), the number (P2), the total foreign trade import and export (E3), and the net profit of the mo The six factors of throughput energy consumption (T1) and water rotation rate ( calculated.…”

“…For example, using the super-efficient SBM model (an efficiency measurement model was improved on the basis of the traditional DEA model, which can exclude constraints whose efficiency value is less than 1.) to measure the energy conservation and emission reduction efficiency of the Bohai Rim port group to evaluate and explore the factors that affect port carbon emission reduction and give corresponding policy recommendations [9]. At the same time, some scholars have conducted research on the use of shore power in ports and have given a carbon emission calculation model [10].…”

“…Studies have shown that rising global temperatures can lead to rising sea levels, shrinking snowpack, and uneven global rainfall. The Paris Agreement proposes that the global average temperature increase should be limited to 2°C this century and strives to limit the temperature increase to 1.5°C above pre-industrial levels [1][2][3][4][5][6] .…”
