Research on the evolution and diffusion of contributor strategy under heterogeneous license of digital open source community
In the process of open source innovation,the breach of contract infringement caused by the illegal use of source code by each participant is not conducive to the construction and development of open source community.Based on the perspective of contributors,a two-party evolutionary game model considering the impact of cost-benefit factors on the evolutionary be-havior of both initial contributors and subsequent contributors at different stages is constructed to discuss the relationship between the intensity of behavior restriction and the infringement of breach of contract.In order to avoid the phenomenon of breach of contract infringement and mobilize the enthusiasm of the majority of contributors for collaborative development,the Lotka-Volterra model is constructed for measuring the development and diffusion trend of dif-ferent types of license agreements.The results show that the increase of non-economic benefit coefficient and protection intensity in the initial stage has a significant effect on curbing the phenomenon of breach of contract infringement,and restricted license agreements occupy most of the market share;in the second stage of evolution,the enthusiasm of subsequent contribu-tors is not high,and the economic benefit coefficient is the key factor affecting the strategic choice of initial contributors.The market share of restricted license agreements still occupies a slight advantage,and the inhibitory effect on loose license agreements is gradually weakened;in the third stage of evolution,with the increase of protection intensity and initial willingness of subsequent contributors,the speed of initial contributors choosing the loose licensing agreement strategy is obviously improved.At this time,the loose licensing agreement has stronger market competitiveness and faster diffusion rate.
