文摘Comprehensively advancing the development of course-based ideological and political education is a strategic measure to fulfill the fundamental task of“fostering virtue through education.”It promotes the integration of ideological and political education with the teaching of various courses,implements the fundamental task of fostering virtue through education,and points out the direction for the teaching reform of engineering majors.Based on the context of course-based ideological and political education,this paper analyzes the importance of integrating ideological and political education into the teaching of Digital Electronic Technology and examines the current situation of ideological and political education in this course.It elaborates on four aspects:compiling ideological and political education cases,actively promoting project-driven teaching,integrating ideological and political education into virtual simulation training,and integrating ideological and political education into the teaching evaluation system.The aim is to improve the quality of ideological and political education in the Digital Electronic Technology course.

文摘Strategically improving carbon emission efficiency(CEE)through digital intelligence technology innovation(DITI)is imperative to capitalize on emerging opportunities for economic decarbonization and low-carbon green development.This study employs panel data from 283 Chinese cities from 2011 to 2021 to examine the influence of DITI on urban CEE.The findings suggest the following:①DITI is crucial in enhancing CEE,and it exerts spatial spillover effects on neighboring areas.②Following the transition to a low-carbon energy system,DITI is instrumental in enhancing CEE by reducing the energy consumption scale,optimizing the energy consumption structure,and controlling the energy consumption intensity.③DITI has varying effects on CEE when subjected to multidimensional regulations,including fiscal pressure,fiscal decentralization,private economics,and entrepreneurial vitality.④The beneficial impact of DITI on CEE is more pronounced in regions with high economic growth,low natural resource endowments,high digital resource endowments,and in cities in central China.This study emphasizes DITI’s crucial role in promoting a low-carbon,green circular,and energy-efficient digital economy.

文摘This paper focuses on how technology services can help small and medium-sized enterprises(SMEs)overcome the digital transformation dilemma of“cannot transform(lack of know-how),dare not transform(fear of risk),and have no money to transform(lack of funds).”Using literature analysis and multiple case comparisons,the study summarizes five major categories of technology services:technical support,consulting and planning,training and empowerment,resource integration,and financing connectivity.It constructs a“service–capability–performance”catalytic framework.Tracking of 58 enterprises in the Yangtze River Delta reveals that resource integration contributes the most to digital maturity,with absorptive capacity playing a significant mediating role;the configuration of“high technology services+high absorptive capacity+high environmental dynamism”is a sufficient condition for high transformation performance.Based on these findings,countermeasures are proposed,including improving the technology service system,strengthening government-industry-academia collaboration,and optimizing funding and talent supply,providing replicable experience for SMEs,governments,and technology service institutions.

文摘While the digital transformation brings new development opportunities to the field of vocational education,it also makes it face unprecedented challenges.In order to adapt to the trend of digital transformation,vocational undergraduate colleges need to improve their school-running level and promote educational reform by building“dual-qualified”teacher teams.Based on this,the author first analyzes the construction requirements of“dual-qualified”teacher teams and the common problems in specific operations,such as the weak practical teaching ability of full-time teachers,the imperfect teacher growth mechanism,and the insufficient in-depth school-enterprise cooperation.Then,aiming at the actual problems,it discusses the advantages and practical paths of building“dual-qualified”teacher teams in vocational undergraduate education empowered by digital technology,aiming to provide suggestions for the high-quality development of vocational education.
