From 2016 to 2019, the operating income of the top 10 securities companies  as a proportion of the industry’s total operating income increased from 40  percent to 44 percent, before slightly decreasing to 42 percent in 2019 (Chart  4). This decrease in 2019 was mainly due to small and medium-sized  securities companies rebounding higher in 2019 on the background of market  recovery and policy reforms. Nonetheless, the top 10 securities companies’  operating income as a proportion of the industry total remained firmly above  40 percent over the past three years indicates that the large securities  companies continue to maintain strong market position. With deepening  capital market reforms and the CSRC move to develop mega-sized securities  companies, this proportion may increase in the long run.
