Indeed, despite Mr. Xi’s austerity campaign, the influence of the rich in Chinese politics continues to grow. While delegates to China’s Parliament, or the National People’s Congress, do not have a lot of power as they rubber-stamp most of the policies set out by the party’s leadership, they get access to top leaders at the gathering. It is also a place that will allow them to network with other potential business partners.

Starting more than a decade ago, the Communist Party, founded to empower workers and peasants and quash the capitalist class, began to welcome wealthy members to broaden its appeal and bolster its authority. Private entrepreneurs now account for about 20 percent of the nearly 3,000 delegates to Parliament, according to government news media.

Among the delegates who will convene at the Great Hall of the People this week are some of the most famous names in corporate China, including Pony Ma, chief executive of Tencent Holdings; Zong Qinghou, founder of the Hangzhou Wahaha Group, a beverage maker; and Lei Jun, founder of the phone maker Xiaomi. The group also includes some Hong Kong tycoons, including Victor Li, the son of Li Ka-shing, the billionaire chairman of CK Hutchison Holdings. Hong Kong, a British colony that was returned to China in 1997, sends delegates to Beijing every March for the meeting.

David Zweig, a professor of Chinese politics at the Hong Kong University of Science and Technology, said he did not think the public would react negatively to the report by Hurun, which also publishes an annual China Rich List.
