地方政府财政支农支出与农村居民消费——来自中国29个省市面板数据的经验证据

本文在消费者最优消费路径选择的基本框架下,构建了一个政府财政支农与农村居民消费的动态最优化模型,理论分析表明:地方政府财政支农支出的增加,对于农村居民消费水平的提高具有促进作用。基于1995-2008年的省际面板数据,采用工具变量GMM方法对该结论进行的实证检验发现:在通过多工具变量克服变量内生性之后,地方政府财政支农支出对农村居民消费具有显著的促进作用,地方政府财政支农支出每增加1%,我国农村居民消费将增加0.1367%;进一步的因素分解显示,地方政府财政支农支出对农村居民消费的平均贡献度为8.72%,且有逐年增大的趋势。此外,财政支农支出对农村居民消费的影响存在区域差异性,即财政支农支出对我国中西部地区农村居民消费的影响程度大于东部地区。     

Consumer coping strategies: a study of consumers committed to eating local

This paper deals with consumer coping strategies when consumers experience difficulties in implementing an innovation. The particular setting for exploring this issue is a group of consumers in Michigan who are committed to eating local. The paper explores how these consumers cope or balance their commitment to eating local with the constraints they face on buying and preparing local food Following a literature review of coping strategy and consumer coping strategies in relation to innovations, the paper presents the results of three focus groups conducted with members of a Student Organic Farm, a food cooperative and a Slow Food Convivium. The consumers we interviewed mostly adopt problem‐centred, confrontative strategies: they change their food‐consumption habits including shopping, purchasing, cooking, storing and obviously, eating. None of these changes are easy to implement, and most require re‐allocations of time as well as trade‐offs to overcome time and cost barriers. In return, some of these consumers feel empowered. This study allows us to offer a working hypothesis that the process is dynamic: the more committed consumers are, the more they adopt problem‐centred, confrontative strategies and forget more fatalist emotion‐centred or avoidance strategies. These findings contribute to literature on consumers' coping strategies and suggest future research avenues.     

The dynamic welfare cost of seignorage tax and consumption tax in a neoclassical growth model with a cash-in-advance constraint

Using a public finance approach, this study investigates welfare costs between seignorage and consumption taxes in a standard growth model. One of these two taxes is used to finance exogenous public spending to balance the government budget. The steady-state welfare cost of consumption taxes is lower if the consumption effect dominates the leisure effect. This paper compares equilibrium along transitional dynamic and steady-state paths and finds that because of lower consumption and leisure and thus higher welfare costs of consumption taxes during early periods, the welfare cost of consumption taxes is larger than the welfare cost of seignorage taxes.     

城镇家庭消费金融效应的地区差异研究

本文使用各省市自治区城镇家庭借贷支出的分类面板数据,结合我国经济发展处于转轨期的特性,考察消费升级、社会保障不完善及地区发展不平衡等因素对消费的影响。研究发现各变量在对消费的影响性质和程度上均存在地区差异,社会保障、消费升级和储蓄在全国范围内均显著正相关,房贷支出和教育在中西部地区的促进作用显著,而保险在东部地区作用突出,家庭投资则均不显著。政府要扩大消费内需并改变消费金融发展的不平衡,就应把握消费升级和社会保障制度的推进时机和力度,增加中西部地区社会保障投入和教育投入,持续提高居民收入,适度放宽中西部地区的家庭房贷限制。     

Environment versus growth — A criticism of “degrowth” and a plea for “a-growth”

In recent debates on environmental problems and policies, the strategy of “degrowth” has appeared as an alternative to the paradigm of economic growth. This new notion is critically evaluated by considering five common interpretations of it. One conclusion is that these multiple interpretations make it an ambiguous and rather confusing concept. Another is that degrowth may not be an effective, let alone an efficient strategy to reduce environmental pressure. It is subsequently argued that “a-growth,” i.e. being indifferent about growth, is a more logical social aim to substitute for the current goal of economic growth, given that GDP (per capita) is a very imperfect indicator of social welfare. In addition, focusing ex ante on public policy is considered to be a strategy which ultimately is more likely to obtain the necessary democratic-political support than an ex ante, explicit degrowth strategy. In line with this, a policy package is proposed which consists of six elements, some of which relate to concerns raised by degrowth supporters.     

中国能源消费、碳排放与工业经济增长——一个脱钩理论视角的实证分析

本文利用相对“脱钩”、“复钩”的理论与测度模型,对2000—2009年我国工业经济增长与能源消费和碳排放之间的脱钩关系进行研究。在此基础上,对脱钩评价模型进行扩展,构建了脱钩指数分解模型,对脱钩关系的影响因素作出了更为深入的分析,并指出未来工业脱钩发展措施的重点方向是在进一步提升能效技术的基础上,着力推进工业产业结构升级的步伐,提升新型低碳能源的结构比重,改善能源的生产和消费结构。     

Marketing and society: Preface to special section on volunteerism, price assurances, and direct-to-consumer advertising

We discuss the reasons why this call for papers was issued and describe the process of selecting the three articles presented in this special section. We argue that maximizing stakeholder welfare and not just consumption maybe a new goal for marketing that will be consistent with emerging societal trends. Three articles on volunteerism, price assurances, and direct-to-consumer advertising result from our call and are presented in this section. This introduction is an overview of the three articles.     

广深客运专线动车组能耗计算与分析

通过对动车组能耗的各种影响因素的分析,按照动车组运行过程的起停、运行、调速制动、出入库等环节,针对每一环节分别研究其能耗计算方法,考虑坡道附加能耗和空调能耗,分别建立数学模型、确定修正系数。研究提供的动车组能耗计算方法可以进行能耗计算与预测,以及对能耗影响因素进行分析。以广深客运专线为例,动车组能耗计算结果与实际能耗的拟合性好,可以为合理确定既有线和客运专线动车组能耗水平提供帮助。     

基于一体化的视角看欧盟税收体系的结构问题与改革取向

欧盟的一体化进程在向各国提出新的税收课题的同时,也使得各国原有的税收问题进一步凸显.在税收结构中,劳动税有一个高税收楔子,对消费税的依赖度很高,而公司所得税和不动产税在总税收中却占一个很小的份额.这种税收结构带来了较低的劳动积极性、较大的税收非中性、较弱的税收再分配能力等问题,并有悖于市场统一化和货币单一化的新形势.这一切决定了欧盟税收体系的改革取向.     

广东省县域农业生产效率分析——基于2015-2019年揭阳市5县域DEA模型为例

农业生产效率提升是实现农业现代化的重要手段。本文以《揭阳市统计年鉴(2015-2019)》的农业相关数据,从县域的视角研究揭阳市农业生产效率,运用DEA模型对揭阳市5个县域的3个投入指标和1个产出指标进行实证分析。结果显示,2015-2019年揭阳市农业生产效率均属于DEA无效,总体效率提升并不明显,且各县域呈现发展不平衡的状态,仅惠来县位于生产前沿面上,普宁市的农业生产效率最低,规模报酬属于递减态势。因此,恰逢“十四五”谋划之时,对揭阳市各县域农业生产效率做出分析研究,为现阶段提升揭阳市农业生产效率提出有参考价值的建议,为广东省县域农业生产效率分析提供范本。
