The service industry in Beijing has been a key player in the region's economic growth. A study looked at the structure and productivity of this industry over the past decade. The findings show that Beijing's industry structure is advanced compared to other countries, with a decline in productive services, especially in information services. The input of productive services from the secondary industry has decreased, impacting the overall economy. This suggests a shift in the demand for productive services, with a decrease in support for the secondary industry being a major factor.
