老字号品牌价值共创机理及对策研究——基于服务主导逻辑视角

将服务主导逻辑的思维范式引入老字号企业中来,结合消费文化和社会情景价值理论探讨该领域中品牌价值的共创机理,基于理论假设构建研究框架。以北京、上海、福建三个地区的不同行业老字号品牌企业为实证研究对象,对企业员工和消费者进行访谈和问卷调查。通过修正的初始量表,基于PLS-SEM方法对收集的309份有效问卷调查数据应用SPSS22.0和Smart PLS2.0进行分析,验证消费者情感价值共创的中介作用及互联网媒介交互的调节作用。分析结果表明,消费者与老字号企业共同创造价值,历史悠久的老字号品牌企业关注基于互联网媒介下不同利益相关者的互动和协同才能创造品牌价值共创的最理想点,最后为老字号品牌管理提供有益的建议和应对策略。     

中国奢侈品消费的动因分析

随着当前我国奢侈品消费人数的不断攀升及奢侈品消费金额的不断提高,中国的奢侈品消费从整体上看未富先奢的局面已经出现。其大致可分为两类：一类是传统奢侈品的消费,消费人群主要集中在超富裕阶层;另一类是新奢侈品的消费,消费人群是中产阶级和白领。从影响我国消费者奢侈品消费的主要动机来看,人际性消费是影响我国奢侈品消费的主要动机,其中符号性消费是影响我国当前奢侈品消费的首要因素。符号性消费、从众性消费与人情消费都属于非理性的消费行为,促使我国奢侈品消费呈现出一种非理性状态。因此．应大力倡导理性消费．同时也要抓住契机。加大宣传营销力度与创新．树立自己的民族奢侈品牌,更好地发施我国经济     

隆线溞(Daphnia carinata king)的呼吸代谢测定

本文用Winkler法测定隆线溞(Caphnia carinata king)不同龄期个体的耗氧量及二幼龄个体在不同温度下的耗氧量。测得幼龄与成龄两阶段,其耗氧量分别以4.88×10~(-2)与1.695×10~(-1)的速率随体重增加而增大,耗氧率则分别随体重的增加而逐渐降低;在常温下,隆线溞耗氧量Y与温度X呈Y=3.69×10~(-3)×1.07~x的指数函数关系,由此得到,17℃—19℃是隆线搔生长速率快而耗氧量较小的最适人工培养温度。     

公平分配与居民福利——收入差距对中国居民恩格尔系数的影响分析

居民收入水平不同,恩格尔系数也不同,因此收入分配对社会总体恩格尔系数的影响是不确定的。基于马斯洛层次需求理论证明边际食品消费倾向递减,并且当消费函数为线性或近似线性时,收入差距扩大会降低恩格尔系数。基于省际面板数据的实证分析表明,中国居民边际食品消费倾向递减且消费函数为(近似)线性,居民收入差距扩大降低了居民恩格尔系数(基尼系数升高对恩格尔系数下降的贡献率为22%),从而出现"分配越不平等,居民总体生活水平越高"的矛盾现象。因此在使用总体指标评价居民生活水平时,收入分配指标必须得到同等的重视;在经济发展中,公平和效率必须兼顾才能实现居民福利最大化。     

Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.     

能源安全体系建构的理论与实践

在我国能源安全面临的一系列重大问题中，能源领域的政策规划薄弱，法律保障制度建设与管理体制改革滞后，能源供应与能源安全保障体系缺乏相关政策、法律和制度的保障。只有真正做到政策、法律和管理体制“三位一体”，才能确保国家能源安全。本文从能源安全体系建构的理论和实践出发，借鉴西方能源安全战略实践，从政策、法律和管理体制等角度，对我国能源安全体系的内在机制建构进行分析，旨在为我国与中东能源合作提供借鉴与参考。     

德莱塞笔下的新女性形象——嘉莉妹妹的个性分析

在美国文学史上,德莱塞塑造的嘉莉妹妹一直是个有争议的人物形象.本文从19世纪末20世纪初美国新兴消费文化和新女性崛起这一特定社会历史背景出发,从自我实现、自主选择、自我塑造三个方面尝试解读嘉莉妹妹这一形象在个性上表现出的新女性内涵.     

消费文化转型的激励机制与“两型社会”的构建

消费文化具有引导、凝聚和激励的社会效应,实现消费文化由传统向现代的转型,对于"资源节约型、环境友好型"社会的构建有着不可或缺的作用.因此,有必要在明确"两型社会"消费文化转型取向的基础上,探求消费文化转型的激励机制,以期对推动"两型社会"的构建进程有所裨益.     

Imposing and Testing for Shape Restrictions in Flexible Parametric Models

In many economic models, theory restricts the shape of functions, such as monotonicity or curvature conditions. This article reviews and presents a framework for constrained estimation and inference to test for shape conditions in parametric models. We show that “regional” shape-restricting estimators have important advantages in terms of model fit and flexibility (as opposed to standard “local” or “global” shape-restricting estimators). In our empirical illustration, this is the first article to impose and test for all shape restrictions required by economic theory simultaneously in the “Berndt and Wood” data. We find that this dataset is consistent with “duality theory,” whereas previous studies have found violations of economic theory. We discuss policy consequences for key parameters, such as whether energy and capital are complements or substitutes.     

The changing practice of eating: evidence from UK time diaries, 1975 and 2000

This paper examines some central themes about change in consumption behaviour through an empirical investigation of the practice of eating. It analyses patterns of food consumption in the UK using time diary data from 1975 and 2000. The practice of eating is decomposed into four component activities which are used to explore systematically the inter-relationships between social processes - such as commodification and temporal fragmentation - and ways of providing and consuming food. It charts the expansion of eating out, the degree to which it substitutes for other eating activities, and the implications of its development for social relations and the temporal organization of daily life. Analysis reveals that food consumption continues to be differentiated along established lines of social division, although the content of those divisions has changed and varies across components of the practice. Increasing commodification of the food chain is documented, but without appearing to have a corrosive impact on household organization or social relationships. While tendencies indicative of temporal fragmentation are revealed, counter-tendencies exist which suggest that the practice of eating is resilient to many forms of external pressure. Finally, the application of a practice-based analytical approach permits critical evaluation of theories of social transformation.
