[Objective] This study aims to investigate how place attachment and the quality of experience affect consumers' intention to repurchase Geographical Indication (GI) agricultural products. [Methodology] Based on the special functional value and symbolic meaning of GI agricultural products, we constructed a five-dimensional model of place attachment for GI agricultural products consumers. Expanding on the original two-dimensional place attachment model, we introduced three connection concepts: nature, society, and emotion. We also combined this model with the quality of experience model and consumer purchase intention model to form a research model of repurchase intention for GI agricultural products. A questionnaire survey was used to collect data (n = 340), and a partial least squares structural equation model was used to test the empirical evidence. [Research results] (1) Place attachment to Geographical Indication agricultural products significantly affects the quality of experience. (2) Quality of experience significantly affects consumer trust and repurchase intention. (3) Consumer trust significantly affects repurchase intention. (4) There is a mediating effect of experience quality between place attachment and repurchase intention; there is a mediating effect of trust in the relationship between quality of experience and repurchase intention. (5) There is a chain mediating effect of “place attachment→quality of experience→consumer trust→repurchase intention” in the model.  相似文献

Within the theoretical field of ethical consumption, the study focuses on consumer behavior and innovative green death practices. While scarcely investigated in the marketing and consumer behavior research domains, at least four main reasons spur to consider the funeral industry as an interesting subject of enquiry: i) the sector boasts of a significant economic relevance; ii) it is extremely impactful from an environmental and social point of view; iii) it is witnessing interesting innovative processes in the direction of social and environmental sustainability; iv) consumer movements are rising all over the world asking for more sustainable death practices. Thus, adopting an augmented version of the theory of planned behavior (TPB), which includes individuals’ environmentally responsible consumption, and egoistic and altruistic environmental concern, the study investigates behavioral intention to adopt innovative green death practices (a green funeral) of people belonging to three different generations: X, Y, and Z. A purposive sample of 627 Italian people participated in an online the survey. Collected data were analyzed adopting an ordinal logit model. The results confirm the TPB predictive power also in the field of green funeral behavioral intention. Furthermore, environmentally responsible consumption and environmental concern – even though only in its altruistic component – positively influence behavioral intention, and generation exerts a moderating effect among the examined constructs. Overall, the research attempts to enrich the literature on ethical consumption by exploring the underinvestigated phenomenon of buying behavior of unsought and end-of-life products, that of green funerals, and provide managerial recommendations to funeral service sellers.  相似文献

近年来,“三农”问题受到极大关注。为了应对外部资源、环境、科学技术等多重压力对农业升级与发展的影响,政府出台了诸多政策支持农业企业的技术研发与创新。本文从政府干预视角分析政府补助和税费返还两种形式的政府创新支持政策对农业企业研发投入的影响,重点分析机构投资者与大股东参与公司内部治理以及社会审计事务机构参与公司外部治理这两者所发挥的不同监督作用。研究发现:第一,不同形式的政府创新支持(政府补助和税费返还)对农业企业研发投入的影响并不一致。政府补助产生替代效应,税费返还则产生互补效应。第二,持股监督(机构投资者和大股东的持股比例上升)能增强政府补助对农业企业研发投入的替代效应,也能增强税费返还对农业企业研发投入的互补效应。第三,审计监督(社会审计事务机构的审计意见)会减弱政府补助支持对农业企业研发投入的替代效应,也会减弱税费返还对农业企业研发投入的互补效应。本文的研究发现为政府制定适宜的创新支持政策,以及合理发挥持股监督与审计监督的内外部治理作用,提供一定的决策依据和理论支持。  相似文献

在供给侧改革背景下,科技保险肩负着为科技创新保驾护航的历史使命。然而,科技保险试点10年来,依然面临需求低迷与供给不足并存的发展困境。其主要根源在于:严重的信息不对称造成市场失灵、“跛行”的财政支持政策不能形成有效激励以及不成熟的行业环境制约。要想走出这一困境,仅仅从需求方着力是远远不够的。科技保险的正外部性和科技保险市场高度的信息不对称,决定了必须从财政支持、产品创新、机制创新、中介培育及信息服务等方面进行供给侧改革。为此,提出应当构建供需并重的差异化财政支持机制、加大与需求侧相匹配的科技保险产品供给、创新科技保险契约模式及运行机制、搭建科技保险中介服务和信息支持平台等建议。  相似文献

The prevailing transitions literature suggests that dynamic firms in postsocialist economies are the result of macroinstitutional reforms leading to the making of markets. This article builds on work in comparative political economy and economic sociology to show that the degree of competitive behaviour of postsocialist firms is determined not by the existence of general market institutions alone but by the kinds of organisational allies firms possess and the kinds of markets they compete in. Using firm survey data across 28 postsocialist economies, the article examines the determinants of competitive restructuring by firms, including product innovation, standards upgrade, financial transparency, and investments in research and development. The article confirms insights from comparative political economy which suggest that dynamic enterprise sectors emerge when governance is effective. However, at the firm level, the article finds that transnational ties and supportive policy environments are most significant in the making of dynamic postsocialist enterprises. The article also highlights important regional variation in firm behaviour and discusses the relationship between institutional frameworks, organisational embeddedness, and firm restructuring in postsocialist economies.  相似文献

[目的]把握区域农产品质量竞争力不仅是促进区域农产品富有竞争力的积极方法,也是稳步提升农产品质量安全的重要做法。[方法]文章运用生态位态势理论,构建了以区域为评价主体的农产品质量竞争力评价体系,并从两个层面对浙江省各地级市农产品质量竞争力进行研究。在纵向层面上,测算了各地级市农产品质量竞争力生态位宽度,对各地级市农产品质量竞争力状态进行了评价和排序。在横向层面上,测算了各地级市农产品质量竞争力生态位重叠度,对各地级市农产品质量竞争力的合作程度进行了评价与区分。最后整合运用生态位协同、生态位扩充等理论,提出浙江省各地级市提升农产品质量竞争力发展策略。[结果]通过区域农产品质量竞争力生态位宽度研究发现,杭州和宁波的农产品质量竞争力较强,其生态位宽度分别为0.103 6和0.103 2,而丽水和舟山农产品质量竞争力相对居后,其生态位宽度分别为0.079 0和0.075 6;通过区域农产品质量竞争力生态位重叠度研究发现,可将全省划分为西北平原区域、东南部沿海区域和西南部山地区域等3个区域,各区域内部地级市可通过协同合作提升农产品质量竞争力。[结论]根据各地级市生态位宽度和生态位重叠度的差异,应采取生态位扩充、生态位协同、生态位分离的策略,从而因地制宜提升区域农产品质量竞争力。  相似文献

With the rapid development of apparel mobile commerce in the United States, more companies view mobile commerce as a new source of competitive advantage. Despite the importance of apparel mobile website quality and its effect on consumer satisfaction and future purchase stimulus, extant research has paid little attention to these topics. This study proposes a website quality–consumer satisfaction–purchase intention research model based on the self-regulatory process theory. Six dimensions of apparel mobile website quality—website visual appeal, apparel visual appeal, brand trust, website information quality, website response time, and website security—were investigated. In all, 293 eligible responses were collected via an online survey. Multiple regression analysis was utilized to test the proposed relationships. Results reveal that website information quality, website visual appeal, apparel visual appeal, and website security positively affect consumer satisfaction toward apparel mobile commerce websites, while website response time and brand trust show insignificant impacts on consumer satisfaction. With higher satisfaction on an apparel mobile commerce website, consumers are more likely to purchase apparel through the website.  相似文献

Flash sale (FS) is a new business model that offers discounted products in limited numbers over a short period. In this paper we discuss the impact of strategic consumers on advance selling (AS) of new products on FS platforms. We first study the impact of strategic consumers on competing retailers adopting AS to sell a homogeneous new product. And find that the retailers’ AS profits and inventory quantities decrease with the strategic customers’ valuation and valuation decreasing rate. Then we analyse whether FS can mitigate the impact of strategic customers on retailers adopting AS for new products. We consider a newsvendor model involving only one retailer adopting AS to sell a new product. We derive the results by comparing this model with two counterpart models, namely the classical newsvendor model with no strategic customers and a newsvendor model with strategic customers where the retailer does not use FS under AS.  相似文献
