文摘The micro-public opinion environment,characterized by information fragmentation,instantaneous dissemination,emotional contagion,and diverse values,has profoundly transformed the information acquisition patterns and cognitive formation processes of college students.It also poses new challenges and opportunities for innovation in ideological and political education(hereinafter referred to as“IPE”)for college students.Starting from the contemporary value of IPE for college students,this paper analyzes the logical connection between the micro-public opinion environment and IPE,thoroughly examines the core challenges faced by IPE in this context,and proposes specific innovative paths from four perspectives:content,methods,subjects,and mechanisms.The aim is to provide insights for enhancing the pertinence and effectiveness of IPE for college students in the micro-public opinion environment.

文摘As urbanization accelerates globally,air pollution-particularly PM_(2.5)-is becoming an increasingly significant threat,not only to public health but also the environment.In-depth research on the impact of China’s Zero Waste City pilot policy on PM_(2.5)concentration offers valuable insights into the policy’s effectiveness and provides a potential model for environmental governance worldwide.This study employs panel data from 293 Chinese cities from 2014 to 2022 to systematically analyze the impact of the Zero-Waste City policy on PM_(2.5)concentration using a difference-in-differences model.The findings indicate that the policy not only directly reduces PM_(2.5)concentration but also indirectly curbs PM_(2.5)emissions by enhancing green innovation and green economic efficiency.Moreover,the policy’s effects are found to be positively moderated by urban energy dependence and digital financial inclusion,while they are negatively moderated by the government debt ratio.Based on these findings,this study suggests that cities should actively develop their digital economy,reduce government debt,promote green innovation,and improve green economic efficiency,as doing so will enhance their implementation of environmental policies and promote sustainable urban development.
文摘Ideological and political education is crucial for implementing the fundamental task of fostering virtue through education.Colleges and universities,as the main front,shoulder the important responsibility of cultivating talent.At present,with the exchange and collision of Eastern and Western cultures,it is necessary to accelerate the effective integration of excellent traditional Chinese culture with ideological and political education in colleges and universities.Firstly,based on college classrooms,excavate the ideological and political elements of traditional culture and integrate them into courses;Secondly,carry out practical activities,such as traditional culture themed lectures and experience activities,to enhance students’cultural identity;Thirdly,build a“Internet+”new system,use new media platforms to spread traditional culture,and strengthen the leading role of ideological and political education,to help build a cultural power.
文摘Purpose–This study summarizes the overall situation of the resources of the national science and technology innovation platform in the railway industry,including the distribution of platform types,supporting institutions,construction sites,professional fields,etc.,to provide a reference for the further improvement and optimization of the national science and technology innovation platform system in the railway industry.Design/methodology/approach–Through literature review,field investigation,expert consultation and other methods,this paper systematically investigates and analyzes the development status of the national science and technology innovation platform in the railway industry.Findings–Taking the national science and technology innovation platform of the railway industry as the research object,this paper investigates and analyzes the construction,development and distribution of the national science and technology innovation platform of railway industry over the years.And the National Engineering Research Center of High-speed Railway and Urban Rail Transit System Technology was taken as an example to introduce its operation effect.Originality/value–China Railway has made great development achievements,with the construction and development of national science and technology innovation platform in the railway industry.In recent years,a large number of national science and technology innovation platforms have been built in the railway industry,which play an important role in railway technological innovation,standard setting and commodification,and Railway Sciences provide strong support for railway technology development.

文摘In the era of green logistics,digital transformation has become an effective means for the logistics industry’s high-quality development.Using listed companies in China’s logistics industry from 2010 to 2021 as the research samples,this paper conducts an empirical test on the impact of the digital transformation of logistics enterprises on their green in-novation.Specifically,enterprise digital transformation indicators are constructed through the text analysis method,and the fixed-effects model is applied for analysis.The results indicate that the digital transformation of logistics enterprises has a significant promoting effect on their green innovation;the promoting effect of the digital transformation of logistics enterprises on green innovation is primarily achieved by easing corporate financing constraints and reducing corporate en-vironmental uncertainty;and the impact of digital transformation on green innovation is geographically heterogeneous.
