With the implementation of “carbon peaking and carbon neutrality” in China, new energy enterprises, as vanguard this strategy, have entered a era innovation-driven development. However, enterprises at different lifecycle stages will face internal external conditions, there are differences their mechanisms business performance. In case, whether technological innovation efficiency can an obviously positive effect on growth what effects it for become issues great concern to company management,...

Under the guidance of high-quality development goals, energy industry should not only pay attention to level but also coordination effect among multiple elements. In process low-carbon development, natural gas plays an important transitional role as a clean fossil energy. this study, by introducing theoretical perspective trilemma, comprehensive measurement system three-dimensional regional was constructed. Then, in order overcome limitation that is weakened due concentration function...

Clarifying the key sectors and influencing factors of carbon emissions from energy consumption is an important prerequisite for achieving “carbon peaking neutrality” goals. This study calculated fuel combustion in 7 major departments regional electricity trading Sichuan Province 2000 to 2021, empirically analyzed impact structure effect, intensity industrial economic development level population size effect on based LMDI model. The main research conclusions are as follows: (1) model has...

Abstract In this paper, a risk analysis method of gas pipeline in karst area based on the integrated model decision-making trial and evaluation laboratory–interpretive structural (DEMATEL– ISM) cross-impact matrix multiplication applied to classification (MICMAC) is proposed. Based causal chain theory crossed track theory, composite accidents established from four dimensions human, material, environment, management. DEMATEL–ISM method, hierarchical structure relationship between factors are...

Clarifying the temporal and spatial characteristics of regional carbon emissions low-carbon efficiency is great significance for realization peaking neutrality. This study calculated in Sichuan Province from 2015 to 2022 based on four major units: energy activity, industrial production, forestry waste disposal, its time evolution key sources were investigated. Meanwhile, Super-SBM-Undesirable model, 21 cities (states) was evaluated, heterogeneity The empirical results reveal following: (1)...

Technological innovation is an important engine to support the development of China from a big manufacturing country powerful country. With government policies, China’s high‐end industry urgently needs solve problems insufficient technological and weak core competitiveness. This paper uses super‐SBM model measure impact incentive policies related on efficiency in 2012–2017. The DEA Malmquist used analyse dynamic change trend efficiency. results show that shows gradual optimization, stepping...

Abstract Long-distance buried pipelines inescapably go through seismic fracture zones which makes the be easily influenced by diastrophism. A strong and resilient pipe can withstand a certain degree of oscillation. However, it is really difficult for to resist permanent ground displacement caused faulting surface damage. Most existing studies only focus on two-phase contact between pipeline soil, mechanical behavior cross-fault under transportation condition has not been studied. In this...

Abstract Buried gas pipelines in karst area are inevitably affected by the geotechnical activities, which is difficult to resist permanent ground displacement caused soil dislocation and surface damage. In this paper, abaqus finite element software has been used establish a pipe-soil nonlinear coupling model based on birth death technique. The influence rules of various sensitive factors stress response studied. work presented paper can provide reference for design safety polyethylene...

Abstract In this paper, the hazard criteria for thermal radiation and shock wave overpressure applicable to deflagration of urban gas pipelines have been proposed. The phast software is used analyze intensity degree pipeline deflagration. Based on criteria, situation personnel object damage determined, targeted risk control points are influence parameters wind speed, atmospheric stability, air humidity, operating pressure studied. work presented in paper can provide a reference disaster...

Artificial Intelligence today demonstrates an astonishing productivity, and its development has become one of the directions for many countries. However, while developing, it is also necessary to consider adverse impact AI on carbon emissions seek environments regions suitable development. To address this issue, paper innovatively proposes concept "fertility" describe potential a region, fully considers emissions. Based emission data various provinces in China recent years, modeled through...

With the rapid development of China's socialist market economy, power industry has become a pillar for national economy. The reform electricity system is also steadily advancing, and competition among companies becoming more fierce. effective improvement performance faces challenges. As an important part enterprise's human resources, executives play extremely role in growth steady company; executive compensation can strength company's senior management team may affect company. This paper...
