中国服务业发展悖论——基于“两波”发展模式的研究

本文借鉴最新文献对服务业发展规律的测度方法,用中国1952—2010年的地区面板数据对我国服务业比重变化的长期规律和阶段性特征进行了测度,结果认为:宏观国家层面上,我国服务业比重的变化确实有悖于世界经济整体服务化的趋势;但在地区层面上,我国服务业比重与人均GDP的关系基本符合"服务业比重随经济发展不断上升"的普遍规律,所谓经济服务化的"中国悖论"在地区层面上并不存在;对服务业发展的阶段性特征和地区差异进行分析发现,我国大部分地区仍然处于以传统服务业为主的第一波发展阶段,只有少数地区进入了以现代服务业发展为主导的第二波。文章最后对我国服务业发展规律的成因进行了一般分析和实证检验。     

石家庄品牌零售商业创新与发展研究

随国家经济体制改革,我国零售市场发生了翻天覆地的变化,使得一批批曾经红火一时的品牌商业经过激烈的市场洗礼被淘汰出局,仅有少数企业始终保持着极强生命力.通过对石家庄品牌零售商业的演进轨迹分析,展开自主创新与商业生命力的探讨,进而对零售商业自主创新策略选择进行研究并提出建议.     

从退堂权的失而复得看"大跃进"饥荒的成因和教训

本文旨在利用最新的历史资料,采取历史逻辑方法,并从自由退出权的丧失和复得的经济学意义,揭示以剥夺自留地、取消家庭副业、对农民的全部口粮实行强制性集体化为标志的公共食堂的兴起、散伙、重新加强和最后的迅速解散,与"大跃进"饥荒的爆发、加剧及突然终结在时间上的重叠并非偶然,而是与这一退出权的丧失和复得有着深刻的内在因果关系.

产业集聚与中国高新技术产品出口复杂度关系研究

笔者在Metilz模型的基础上建立了产业集聚对高新技术产品出口复杂度的促进作用机制的理论模型,利用2005年～ 2011年间我国25个省、市、区相关数据就产业集聚对高新技术产品出口复杂度的作用影响进行了实证研究,结果表明:产业集聚对高新技术产品出口复杂度的作用影响显著;不同区域的产业集聚水平差异导致了区域出口复杂度存在明显的差异;提高产业集聚水平是促进一个国家出口商品技术含量提升的重要途径.     

维格列汀与二甲双胍合用治疗糖尿病的药物经济学研究

目的比较维格列汀、吡格列酮、格列美脲分别与二甲双胍合用治疗2型糖尿病时的效果、成本及成本-效果。方法运用Markov模型对三种治疗方案的终身治疗成本及效用（期望寿命、质量调整寿命年）进行经济学评价,通过文献资料和专家问卷咨询获得临床、生命质量、并发症年治疗成本等数据,进行敏感度分析。结果维格列汀、吡格列酮、格列美脲分别与二甲双胍合用治疗2型糖尿病分别延长11.02、10.96、10.90个质量调整生命年,而生命周期中三种治疗方案的治疗费用分别为124892元、134135元、126010元。敏感度分析证明了结果的可靠性。结论与吡格列酮、格列美脲合并二甲双胍质量相比,维格列汀合并二甲双胍治疗获得的健康效果更好,而治疗成本更低。     

二元财政的制度变迁：基于路径依赖的视角

植根于二元经济结构的二元财政制度总是执行有利于城镇部门发展,而且有损于农业部门发展的财政税收政策。这不仅造成了农村居民的长期贫困,而且还持续拉大城乡差距。基于新制度经济学的制度变迁分析结果显示,二元财政的制度安排内含自我增强机制,其变迁具有明显的路径依赖特征,所以,农村居民的贫困必然具有长期性,城乡差距也会持续拉大。因此,必须根据中国经济现实,对二元财政制度采取边际调整的改革措施和借助市场化的手段改善其赖以存在的经济环境,方可在长期内从整体上推动二元财政制度变迁,实现城乡平等的财政制度。     

技术进步对中国就业影响的实证研究

选取1978—2008年中国30个省市的面板数据,运用DEA方法测算中国的全要素生产率及其分解项:技术变化与技术效率,并使用ARDL模型实证分析技术效率和技术变化对就业的影响。研究发现:技术效率无论是长期还是短期都对就业具有显著的抑制效应,但在短期中,技术变化当期对就业没有显著影响;而滞后期技术变化的改善也会对就业人数的增加产生抑制效应,同时,在长期中,技术变化对就业有着显著的促进效应,可以带动就业量的增加。     

The time cost of food at home: general and food stamp participant profiles

Little is known about the cost of time in food preparation at home. Yet, this economic variable is a common thread running through recent concerns about obesity and the Food Stamp (FS) program. This article provides initial estimates of the time cost in food preparation at home for the United States. Two standard methods of estimation are implemented and three demographic profiles are considered: (i) the general population, (ii) the typical FS participant and (iii) the typical FS participant following the United States Department of Agriculture Thrifty Food Plan. For the general population and averaging across methods, the time cost share of total food cost is about 30% if the individual works in the market and at home, but it is about 49% if the individual does not work in the market. For the typical FS participant, especially one following the Thrifty Food plan, the time cost share of total food cost can be as much as 26% higher than the general population. These substantial percentages provide strong incentives to purchase food away from home and help undermine overall diet quality and the efficacy of the FS program, which ignores the time cost in food at home production.     

Some Taxation Theorems in the Hotelling Model

In this paper, we investigate the relationship between the demand ad valorem, cost ad valorem and unit taxes in terms of price, quantity and tax revenue. In particular, we prove that the Musgravian transformation holds in the Hotelling model. In addition, we show that the Suits‐Musgrave theorem must be revised as output in the Hotelling model remains invariant in the presence of different taxes. That is, for a given price instead of a given output, the tax revenue under demand ad valorem tax exceeds that under the corresponding unit tax as long as profit levels for both stores are positive, a very general assumption. The exception is when the two stores are located close to each other and transportation cost is zero. Only in this case, are tax revenues and price under both tax regimes the same. If both stores are symmetrically located, the superiority of the ad valorem tax holds true except when the two stores are located back to back. Finally the farther away the location of a firm from the end point is, the smaller the difference in tax revenues between demand ad valorem and unit tax will be: the effect of the Suits‐Musgrave theorem weakens in the presence of location clustering.
