Introduction to the special issue on "the twin (digital and green) transition: handling the economic and social challenges"

In an era of increasing global challenges, two paradigmatic shifts - the digital and green transitions - have gained traction due to their potential impacts on industrial ecosystems and societal inequalities. Termed the 'twin transition', these shifts underscore the synergies between technological advancements and environmental sustainability. Highlighting its importance in post-COVID-19 recovery, the special issue examines the twin transition's potential to drive industrial innovation and affect social, economic, and geographical inequalities. The seven articles in this special issue explore the impact of the twin transition on corporate innovation strategies and investment, alongside the economic, social, and geographical implications. Key findings underscore the need for diversified technological investments, especially in AI, and enhanced digital infrastructures. Policy recommendations advocate for aiding firms lagging in digitalisation and developing region-specific innovation policies. The research sets a roadmap for future inquiries into the interplay of digital and green transition, broader economic impacts, and policy-driven strategies.
