In recent years,the internet business model has become a popular concept,and has been adopted by an increasing number of traditional ***,the question remains whether this adoption is a strategy-driven decision or a blind follow of ***,this study is conducted on Chinese listed companies from 2007 to 2020 to examine the existence,underlying motives,and economic consequences of peer effects in traditional enterprises adopting internet business *** results show significant peer effects among traditional enterprises adopting internet business *** examination of driving mechanisms reveals that peer effects of internet business models are more significant in enterprises with asset-light structures,higher degrees of virtualization,lower market valuations,and greater financing pressure,supporting the conceptual catering hypothesis rather than the strategic drive *** tests reveal that while adopting internet business models enables enterprises to receive some government subsidy and market reaction in the short term,it only promotes tactical innovation rather than real innovation and does not improve the financial performance of these *** further indicates that peer effects of internet business models are not a strategic drive but rather a matter of conceptual catering.

This paper investigates region tracking and perimeter surveillance of second-order multi-agent systems, where all agents move within a star-shaped set. First, by coordination transformations,the region tracking problem is converted from the star-shaped sets to a circular region. The authors employ communication and collaboration to complete region tracking and perimeter surveillance tasks,and then revert back to the star-shaped set by using inverse transformations. Second, the authors propose a distributed control strategy based on attractive and interaction potential functions, under which all agents can quickly track a given circular region and move around the perimeter. Finally,the authors validate the effectiveness and performance advantages of the proposed method through simulation experiments.
