Research On Influencing Factors Of Public Attention And Sentiment Of Secondary Water Supply Based On Sina Weibo

Middle and high-rise buildings mainly rely on secondary pressure to supply tap water,which is called "secondary water supply".Due to the limitation of water supply mode and the confusion of management rights,the phenomenon of poor water quality,unreasonable charges and unmanned management of secondary water supply occurs frequently,which has aroused widespread concern.In February 2015,the four ministries and commissions jointly issued the Notice on Strengthening and Improving the Construction and Management of Secondary Water Supply Facilities for Urban Residents to Ensure Water Quality Safety,which clearly pointed out that "Safeguarding Secondary Water Supply will be upgraded to the height of improving people's livelihood and national anti-terrorism strategy".Due to the complexity and diversity of participants in secondary water supply,the government,enterprises,media and the public often make different voices around the issue of secondary water supply.The focus of public attention and emotional awareness of secondary water supply and its formation mechanism are not clear,leading to the uncertain direction of urban water supply security promotion.Therefore,based on the microblog data,the following work is carried out in this paper:(1)Using the procedural grounded theory and method,this paper explores the interactive process of different participants around the secondary water supply problem.Firstly,through open coding and spindle coding,six main categories such as problem explosion and knowledge popularization are identified.Secondly,through selective coding,the core category of "secondary water supply main body interaction mode" is refined,and the theoretical model of secondary water supply main body interaction mode is established.Finally,it is concluded that the information circulation between the main bodies of secondary water supply and the knowledge popularization and product promotion of the relevant subjects reduce the occurrence of secondary water supply problems,and realize the good cycle of interaction between the main bodies of secondary water supply.(2)Combining with large data research methods,this paper explores the focus of public attention on secondary water supply,focus formation mechanism and influencing factors.Firstly,according to the categorized results,the public's attention to secondary water supply is analyzed,and the conclusion is drawn that the secondary water supply information issued by different participants can arouse high attention.The second water supply transformation is the most concerned in government information,and the water quality and water shutdown are the most concerned in public information.Secondly,combined with Goffman framework theory and Shannon & Weaver's information dissemination model theory,this paper constructs the information dissemination and mechanism model of public attention to secondary water supply,and puts forward the hypothesis of influencing factors of public attention to secondary water supply,and makes an empirical analysis using OLS regression model.The results show that the economic level of the recipient area,the types of secondary water supply events,and the time of information release.Intermediate,network penetration rate and user influence significantly affect the public's attention to secondary water supply.(3)Using the method of big data analysis,this paper analyses the public's affective tendency towards secondary water supply and the influencing factors of affective tendency.Firstly,through the NLPIR data analysis platform,the public's emotional tendency is calculated and analyzed,and the conclusion is that the public has the most negative emotions about the secondary water supply.Secondly,based on the previous literature,this paper puts forward the hypothesis of influencing factors of public emotional inclination of secondary water supply,and makes an empirical analysis by using Order Logit regression model.It concludes that the higher the government's activity and influence,the higher the probability of generating positive emotions;the stronger the perceived effect of the enterprise's environment,the higher the probability of publishing negative emotional information for profit.Finally,the paper puts forward policy suggestions:(1)Strengthen the publicity of secondary water supply transformation and popularization of secondary water supply knowledge;(2)Strengthen the construction of government micro-blog platform,improve its influence and activity,make full use of the influence of government micro-blog to guide the direction of secondary water supply public opinion;(3)Correctly guide residents to secondary water supply through water supply open day,soft paper promotion and other ways.Affective recognition;(4)Strengthen the quality supervision of secondary water supply equipment and the quality monitoring of secondary water supply to ensure the safety of secondary water supply.
