再议因患寡而患不均:中国家庭住宅权属差异及其对内需增长的影响

住宅权属差异导致了家庭住宅财富差异,进而影响了家庭消费偏好.本文基于一个非住宅耐用品消费决策的随机最优控制模型,采用1991—2006年 CHNS 数据并运用动态面板数据模型,考察了家庭住宅权属差异对耐用品消费的影响.本文的主要发现是,同理论预期一致,自有住宅家庭的耐用品消费明显高于租住房屋家庭,而且住宅权属消费效应随着家庭脆弱性增强而下降.本文的政策含义是要通过降低家庭脆弱性、创新保障性住房分配模式来缩小居民住宅权属差异和促进消费增长     

论消费需求新趋势及其对企业营销工作的影响

当今社会的消费需求呈现出不少新的特征,在需求层次、价值取向、消费手段等方面都发生了质的变化.这些变化对企业营销工作带来了许多新的问题,企业应积极转变营销观念,寻找新的营销策略.     

消费结构升级与技术进步

文章将技术进步分解为技术效率与技术创新,并沿着成果转化、自主创新和技术模仿等路径,探讨了消费结构升级对技术进步的影响及条件。文章认为,消费结构升级引导着资源的配置方向;沿着不同的路径,消费结构升级带来了不同形式的技术进步。一方面,消费结构升级可促进科技成果转化,在生产前沿不变的条件下提高技术效率。当发明专利得到更好的保护时,生产者推动成果转化的积极性会提高,这时,可用的科技成果越多,消费结构升级越能推动技术效率提升。另一方面,消费结构升级还能推动企业突破现有的生产前沿,实现技术创新。由于小企业运营更灵活、竞争压力更大,在企业平均规模较小的市场结构中,消费结构升级更能推动技术创新;而政府主导的研发往往缺乏行业需求等信息,可能与消费者的实际需求脱节,因此,政府主导的研发投入越多,消费结构升级越难拉动技术创新。不仅如此,在开放条件下,企业还可以通过模仿去满足消费结构升级带来的新需求,进口越多,模仿的空间越大,这种模仿会提升技术效率,但可能会不利于技术创新。基于1999-2015年的省级面板数据,文章对上述假说进行了检验,结果表明上述论断成立。     

中国家庭股市资产价值变动对居民消费的影响——来自CHFS的微观证据

近年来针对股市资产价值变动与消费关系的研究多采用宏观数据,难以揭示股市资产价值变动对居民消费影响的细节。为克服以上缺陷,文章利用中国家庭金融调查（CHFS）数据分析股市资产价值变动对中国居民消费的影响。实证结果表明：（1）股市资产价值变动对居民消费的影响总体较弱,其中市值变动的财富效应主要体现在改善性消费上,而对饮食等日常必须消费和奢侈品消费影响较小,这可能与我国居民的收入结构和投资方式有关;（2）随着年龄增长,居民的收入分布和资产配置倾向发生改变,股市资产价值变动对不同年龄居民消费的影响呈现先减小后增大的U型分布。研究结论揭示了股市资产价值变动对居民消费影响的分布特征,为今后股市改革方向提供了建议。     

劳动力流动与中国农村居民消费结构——基于LAIDS模型的实证研究

使用1992~2011年的时间序列数据,采用线性几乎理想需求系统模型(LAIDS),重点检验了劳动力流动对农村居民消费结构的影响。研究发现,劳动力流动会使衣着、文教娱乐及服务、医疗消费有所增加,会减少食品、居住消费,对家用几乎没有影响。为此,应增加工资性收入,完善劳动力流动政策和供给结构。     

中国消费率和投资率的合理性判断：1978-2005

无论从国际比较,还是从对中国资本生产率以及增量资产产出率的分析来看,中国消费率显著低于国际水平,而投资率显著高于国际水平,且偏低的消费率与偏高的投资率存在着明显的不协调。     

Monetary policy and food inflation in South Africa: A quantile regression analysis

Although optimal monetary policy stabilizes food inflation theoretically, empirical studies remain limited not only in the context of volumes and the estimation approaches, but are focused on selected advanced and emerging countries to the neglect of Africa where poverty and dominance of food in the consumption basket are more pronounced. We provide empirical evidence in the context of South Africa using quantile regressions. Rising food prices are destabilized even further by restrictive monetary policy; a finding that has ramifications for inflation targeting, especially given that a quarter of the country’s population is food poor.     

民族自治地区三公经费公开问题研究

针对民族自治地区这一特殊行政区域,指出“三公经费”公开目前存在公开意识不足、公开内容简单、真实性偏低、公开渠道受限及反馈性不足等问题。提出了应从思想意识上深入开展群众性教育、规范三公经费公开内容,严格要求随表附上说明、严格监督、建设多渠道公开平台并建立交流反馈机制等完善思路。     

Got milk? The rapid rise of China’s dairy sector and its future prospects

This paper synthesizes recent research and new empirical findings to build a more comprehensive understanding of developments in China’s dairy sector. China’s tremendous rise in dairy demand has been driven by several mutually reinforcing factors: including rapid income growth, promotion by the government and dairy industry, changes in urban lifestyles, and the development of new, more sophisticated marketing channels. Domestic milk output has grown to satisfy rising demand largely by increasing the dairy herd. Substantial increases in productivity have been achieved through technology adoption, but there is evidence that the torrid growth has created inefficiencies because adaptations to marketing rules, infrastructure, and institutions have not kept pace with the changing environment. These results suggest there is ample room for future growth in both domestic milk production and dairy demand, but multinational firms and imported products will likely play and increasing role as China’s dairy market continues to develop.     

Demand for dairy products in the EU

In the EU dairy sector, given the remaining high protective tariffs and the quota system, the main factor that drives dairy product market prices is the demand. This paper evaluates the development of demand in the EU and presents estimates of consumption trends and forecasts for the future as well as estimates of elasticity with respect to prices and income in two major EU consumer countries: France and Italy. We use two methods to estimate the development of demand for dairy products, one based on a multi-stage demand system and another based on a single trend equation. The two methods generally lead to the same qualitative results but trend projections are larger using the demand system approach which is based on a shorter data period. This difference is thus partly explained by the fact that high trend projections are not sustainable over a long period. The results show a decreasing consumption of butter and fluid milk and an overall growth in protein and fat consumption. Nevertheless, the increase in fat consumption should be more moderate than the consumption of protein. The results also show that the demand for dairy products is relatively price inelastic but is more sensitive to changes in income (especially for butter and cheese categories). As shown by the use of a partial equilibrium model of dairy markets, the likely impact of the CAP reform strongly depends on the development of demand for dairy products in the EU. More research effort on demand analysis is therefore crucial in order to assess the impact of reforms or trade negotiations more accurately and effectively.
