Subway Operation Boosts Enterprise R&D Investment in China
According to a recent study, the development of subway infrastructure in China has a positive impact on enterprise research and development (R&D) investment. The research, conducted by a team of investigators from the Nanjing University of Aeronautics and Astronautics, explored the link between subway operation and enterprise R&D investment using panel data from listed manufacturing companies in China from 2008 to 2020. The study found that the rapid development of China's subway system has increased enterprise R&D investment, particularly in companies with high employee compensation, non-state-owned enterprises, and large enterprises.
Key Takeaways:
- The study found that the rapid development of China's subway system has increased enterprise R&D investment by 15.6% since 2008.
- The positive impact of subway operation on R&D investment is more significant in enterprises with high employee compensation, non-state-owned enterprises, and large enterprises.
- The study employed the time-varying difference-in-differences method to explore the impact of subway operation on enterprise R&D investment.
- The results showed that new subways have increased enterprise R&D investment, and that the subway's positive impact on R&D investment is more significant in enterprises with high employee compensation, non-state-owned enterprises, and large enterprises.
- The study concluded that subway operation promotes enterprise R&D investment by attracting tech talent and promoting infrastructure convenience.
- The research has been peer-reviewed and published in the Technology Analysis & Strategic Management journal.
