According to hedonic price theory, people's demand for product is based on the characteristic. Pu'er tea geographical indicator of Yunnan province, which has edible, medicinal, drinking, investment and cultural value. It a typical multi-characteristic product, bubble possibility large, but degree not been tested, detection effect clear. So, this paper applied four products as study case, generalized sup ADF statistic model (GSADF) respectively detect bubbles Back-ProPagation Network (BP)...
Abstract This paper summarises the concepts of Internet things and its examples application in libraries throughout world. Given existing university library digital infrastructure, a development path for our national intelligent based on was studied detail from three aspects. We hope more will move towards true libraries.
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 supply-demand, Yunnan supply, supply-demand and level factors during 2012–2019, using technique order preference by similarity to ideal solution method (TOPSIS) have empirical research. The results show that a great influence on price. of factors, increased year year. Therefore, enhance product...
Pu'er tea, as the geographical indication product of Yunnan province. The price tea will affect healthy development industry and further economic According to characteristics current detection methods, this paper uses four products sample data selects GSADF method detect bubble tea. results showed: (1) During period from 12 June 2012 24 November 2019, there were bubbles in year Dayi 7542 raw 7572 ripe 2011 while no tea; (2) There periods three Through analysis, it can be known policy...
Abstract Food safety governance and its performance improvement are inseparable from the cooperation of multiple subjects. The extensive participation consumers is not only a powerful supplement to deficiency supervision resources but also an intrinsic request for seeking both temporary permanent solutions food problems. To ascertain factors mechanisms that influence consumers’ willingness social co-governance, integrated conceptual model was constructed based on Theory Planned Behavior...
Pu’er tea as the landmark product of Yunnan province, which plays a decisive role in national industry and economic development province. At present, qualitative quantitative methods cannot be accurately predicted price tea. In order to solve this problem, paper tries use MLP neural network forecast price. Firstly, determine influencing factors price, then established model, selection activation function design number neurons hidden layer size, finally compare method between random forest...
Enterprise product shows many characteristics, thus, pricing is an essential strategy of enterprise, but the multi-characteristic enterprise method does not adapt to dynamic and changeable market demand. As a artificial intelligence, prediction ability BP (Back ProPagation Network) has been questioned challenged. Therefore, this article established intelligent research system for products, through GSADF (Generalized Sup ADF Statistic) model, measured price bubble products; TOPSIS (Technique...
Farmland shelterbelt system (FSS), as an effective agriculture management with fine ecological effects, has been widely carried out in fragile agricultural areas. Clarify the impact mechanism of FSS on environmental factors and ecosystem functions a vital guiding role to FSSs’ construction restoration ecosystems. In Hetao irrigated area northern China, four typical patterns (i.e. two lines pattern, TWLP; FOLP; five FILP; eight EILP) were selected measure soil properties (0-100 cm),...
