Food safety governance and its performance improvement are inseparable from the cooperation of multiple subjects. The extensive participation of consumers is not only a powerful supplement to the deficiency of supervision resources but also an intrinsic request for seeking both temporary and permanent solutions to food safety problems. To ascertain the factors and mechanisms that influence consumers’ participation willingness of food safety social co-governance, an integrated conceptual model was constructed based on the Theory of Planned Behavior (TPB) and Benefit-Risk Analysis (BRA). 664 valid questionnaires collected in China were used to verify the hypotheses with the application of the Structural Equation Model (SEM). The results showed that behavior attitude, subjective norm, and perceived behavior control significantly impacted consumers’ participation willingness, and the influence strength was in the sequence of perceived behavior control, behavior attitude, and subjective norm. Perceived risk and participation willingness showed a strong negative relationship. Besides that, perceived risk also played a partial mediation role in predicting behavior attitudes toward consumers’ participation willingness. According to the conclusions, a series of policy suggestions were also proposed to help improve consumers’ participation willingness.

This paper summarises the concepts of the Internet of things and its examples of application in libraries throughout the world. Given the existing university library digital infrastructure, a development path for our national university intelligent libraries based on the Internet of things was studied in detail from three aspects. We hope more university libraries will move towards true university intelligent libraries.

Pu'er tea, as the geographical indication product of Yunnan province. The price of Pu'er tea will affect the healthy development of the tea industry and further affect the economic development of Yunnan province. According to the characteristics of Pu'er tea price and current price detection methods, this paper uses four products as sample data and selects the GSADF method to detect the price bubble of Pu'er tea. The results showed: (1) During the period from 12 June 2012 to 24 November 2019, there were price bubbles in this year Dayi 7542 raw tea, this year Dayi 7572 ripe tea and 2011 Dayi 7572 ripe tea, while there were no price bubbles in 2011 Dayi 7542 raw tea; (2) There were four bubbles periods in this year Dayi 7542 raw tea and 2011 year Dayi 7572 ripe tea, while there were three bubbles periods in this year Dayi 7572 ripe tea. Through analysis, it can be known policy adjustment, sales way and method, climate, labour cost, the publishing of new products and other factors are the important impacts on the price of the Pu'er tea.

This paper combination with the Internet + environment, constructed an evaluation index system for Pu'er tea price impact mechanism from five dimensions including economic development level, national tea supply-demand, Yunnan tea supply, Pu'er tea supply-demand and Yunnan Internet development level factors during 2012–2019, and using technique for order preference by similarity to ideal solution method (TOPSIS) to have an empirical research. The results show that economic development factors and Yunnan Internet development level factors have a great influence on price. The influence of national tea supply-demand factors, Pu'er tea supply-demand factors and Yunnan Internet development level factors on the price increased year by year. Therefore, enhance product competitiveness, plan production and business activities reasonably and using internet thought are important work for the industry future development. [ABSTRACT FROM AUTHOR]
