Abstract The paper uses the complex network theory to analyze the source channels, transmission characteristics and influence factors of the quality and safety information in news websites. With the analysis of statistical indexes in complex network such as degree and path, we find the static topology characteristics in the process of product quality and safety information transmission. We also analyze the specific factors that influence the dynamic evolution of product quality and safety information transmission network from overall network characteristic, local network characteristic and evolution time. The deep analysis of the characteristics of product quality and safety information transmission is beneficial to building the product quality and safety information transmission model and prediction model. It’s significant in building and improving the risk monitoring system of product quality and safety and evading the harm brought by product quality and safety problem effectively.

Introduction In recent years, with the fast and constant improvement of science and technology, product quality and safety has become the focus of attention and public opinion. Product quality and safety is not only related to the health and safety of most people, but also the healthy development of national economy and social harmony and stability. When product quality and safety problems occur, the related information will be transmitted on the Internet through forum, website, blog, micro-blog, instant messaging tools with tremendous speed. The Internet news site is the main medium for product quality and safety information transmission. The Internet news site means the Internet website built by news units and its information transmission has the characteristics of wide source, fast transmission speed and broad scope of influence. The information is easily discussed in the socialized media. The deep discussion and research of the transmission channel, process, characteristics and influence factors of product quality and safety information in news websites is beneficial to mastering the transmission law of quality and safety information, building and improving the risk monitoring system of product quality and safety. It’s significant in effectively evading the harm brought by product quality and safety problem and securing the safe operation of national economy and social stability. Complex Network Theory The research of complex network is permeating many different fields such as mathematics, life science and social science. The scientific understanding of the quantitative and qualitative characteristics of complex network has become an important and challenging subject of the scientific research in the network era. Complex Network means the network which has self-organizing, self-similar, attractor, and small world, without part or
