People's enthusiasm to copy top leaders' shopping choices might be a new driving force in the consumer market, a sociology expert said.

On April 11, Premier Li Keqiang visited a convenience store in Haikou, capital of Hainan province, and bought a package of coconut crisps and coconut milk rolls that cost 19 yuan ($3.05).

News of Li's purchase spurred a shopping frenzy among consumers seeking the "Premier Package", the two snack foods produced by Wenchang Chunguang Foodstuffs, a local food manufacturer.
