乡村振兴是时代的使命,乡村振兴的基础是经济的振兴,关键是新时代理念下的集体经济发展。只有集体经济发展了,才能充分体现社会主义农村经济制度的优越性,适应乡村全面振兴的要求,为乡村基层组织提高引领力、组织力和战斗力奠定基础;为乡村经济、政治、文化与环境全面协调发展提供支撑,为乡村居民实现美好生活建立基本保障。而乡村集体经济发展的重要途径在于始终坚持习近平总书记提出的具有普遍指导意义的"晋江经验";在于坚持因地制宜地选择产业、依托龙头企业,在城乡统筹中走抱团发展之路;在于坚持辩证统一观念下的"口袋"与"脑袋"、经济与社会、内涵发展与外在协作的协调与推动。  相似文献

The aim of this paper was to study the structural relationship on an path analysis between 13 se-lected variables, explaining a model of occupational health and labor climate: variables of culture (leadership and organizational support), climate (communication and cohesion), burnout (wear emo-tional, depersonalization and dissatisfaction achievement) commitment (affective, normative and continuity) and psychosomatic manifestations (sleep, gastrointestinal and pain). A sample of 1629 subjects of a multinational telecommunications company was used. Two structural models were performed in path analysis using AMOS-IBM version 19, program using the maximum likelihood method, after appropriate testing setting, a path model with 12 significant variables was obtained, eliminating organizational support perceived, a satisfactory reliability was obtained by Cronbach's alfa, the model can be compared and improved in subsequent studies. The burnout explained by route analysis, the importance of a good organizational climate and culture to increase affective commitment, and decrease psychosomatic manifestations. As a model of occupational health, the findings are important for the diagnosis, prevention or intervention in occupational health through studies of organizational climate.  相似文献

Research on vulnerable consumers remains unfailing in macromarketing and social marketing. Yet it is unclear how to operationalize the vulnerable consumers by demographics and further to this it is rarely touched how the vulnerable consumers defined by different measures make decision when choosing the place to shop especially in pharmacy retailing sector. The authors conduct a comparative study of variously-defined vulnerable consumers for their shopping store types in an urban Chinese city to investigate how people with distinct backgrounds develop their decision making rules and choose different types of retail pharmacies. This paper casts light on customer heterogeneity associated with different dimensions of vulnerability by using consumer demographics, and indicates that four dimensions of vulnerability exist as cognitive capability, social relations, behaviors, and the institutional protection in health-related sector. These four aspects of vulnerability play a significant role in identifying different shop selection patterns. Findings suggest that efforts to boost store patronage targeting on various consumer groups should have different strategies to reach consumers’ mindsets.  相似文献

In today’s online environment, consumers and sellers interact through multiple channels such as email, search engines, banner ads, affiliate websites and comparison-shopping websites. In this paper, we investigate whether knowing the history of channels the consumer has used until a point of time is predictive of their future visit patterns and purchase conversions. We propose a model in which future visits and conversions are stochastically dependent on the channels a consumer used on their path up to a point. Salient features of our model are: (1) visits by consumers are allowed to be clustered, which enables separation of their visits into intra- and inter-session components, (2) interaction effects between channels where prior visits and conversions from channels impact future inter-session visits, intra-session visits and conversions through a latent variable reflecting the cumulative weighted inventory of prior visits, (3) each channel attracts inter-session and intra-session visits differently, (4) each channel has different association with conversion conditional on a customer’s arrival to the website through that channel, (5) each channel engages customers differently (i.e., keeps the customer alive for a next session or for a next visit within a session), (6) the channel from which there was an arrival in the previous session can have an enhanced ability to generate an arrival for the same channel in the current session (channel persistence), and (7) parsimonious specification for high dimensionality in a low-velocity, sparse-data environment. We estimate the model on easy-to-collect first-party data obtained from an online retailer selling a durable good and find that information on the identities of channels and incorporation of inter- and intra-session visits have significant predictive power for future visitation and conversion behavior. We find that some channels act as “closers” and others as “engagers”—consumers arriving through the former are more likely to make a purchase, while consumers arriving through the latter, even if they do not make a purchase, are more likely to visit again in the future or extend the current session. We also find that some channels engage customers more than others, and that there are interaction effects between the channels visited. Our estimates show that the effect of prior inventory of visits is different from the immediate prior visit, and that visit and purchase probabilities can increase or decrease based on the history of channels used. We discuss several managerial implications of the model including using the predictions of the model to aid in selecting customers for marketing actions and using the model to evaluate a policy change regarding the obscuring of channel information.  相似文献

创造性地对空间计量经济学中的空间相关性思想进行嫁接利用,在思路方法上进行开拓,构建反映同行业内企业间相互联系与各行业间相互关联的空间权重矩阵,建立空间杜宾模型,并以制造业为例,对ODI逆向技术溢出效应的行业内和行业间路径进行实证检验。对行业内路径的检验表明,企业全要素生产率受到同行业内其它企业ODI活动的影响,行业内企业通过ODI促进自身技术进步之后,又通过企业间各种竞争合作关系促进同行业其它企业生产率提高,行业内路径由此得以验证。对行业间路径的检验表明,各行业通过ODI促进本行业技术进步之后,又通过行业间前向与后向产业关联,对其它关联行业的技术进步和生产率提高起到促进作用,且产业完全关联下的促进作用大于直接关联,由此行业间路径得以验证。  相似文献
