我国东部地区社会管理水平测度及分类研究——兼论社会管理水平与经济发展的关系

东部地区社会管理实践活动对全国具有示范效应。文章首先构建了包括社会保障、社会安全、公共服务和社会参与4个一级指标、25个二级指标的社会管理评价指标体系,为东部地区社会管理水平测度研究提供了科学的评价标准;其次,基于2011年东部11个省份的横截面数据,对东部地区社会管理水平进行了测度,并将其划分为社会管理水平较高、社会管理水平一般和社会管理水平较低三个等级区域;最后,依据社会管理水平及子系统的协调度,进一步将东部地区社会管理水平划分为6种类型,并通过相关性分析,检验社会管理水平及子系统水平与经济发展的相关关系。研究结果表明,2011年东部地区社会管理水平及子系统水平较低,省际间差异明显,且子系统水平呈现非均衡发展特征;社会管理水平与经济发展水平呈现显著正相关关系。因此,促进区域协调发展,增强区域经济实力,能够为提升社会管理水平提供物质保障。     

Coordination in retailer-carrier channels for long term planning

We study a retailer-carrier channel for the purpose of long term planning and coordination. Here, the term channel represents the business interaction between the retailer and the carrier. The retailer sells a particular item with price-dependent demand, whereas the carrier is responsible for transporting the item to the retailer's site. We characterize the profit functions of each channel member as well as the total channel profit. We consider two specific channel structures: (i) the centralized channel and (ii) the decentralized channel. Under the first channel structure, the goal is to set the retail price so as to maximize the total channel profit. Under the latter, the carrier and the retailer choose their own policy parameters, i.e., the freight rate for the carrier and the retail price for the retailer, so as to maximize their individual profits. We model the decentralized channel as a Stackelberg Game and propose a coordination mechanism between the retailer and the carrier in which the retailer signals a price multiplier to the carrier. We illustrate that this mechanism could provide win-win solutions for both parties and present analytical and numerical results on the efficiency of channel coordination. We demonstrate that coordination in retailer-carrier channels can be as promising as supplier-retailer channels. We also discuss the effects of retailer-carrier coordination on inventory levels.     

The role of program fairness in asymmetrical channel relationships

Managing distributor compliance with manufacturer-initiated programs is critical to both program success and relationship enhancement. This study examines how a manufacturer might better motivate distributors with varying levels of dependence. Previous research suggests that two variables influence distributor compliance: economic incentives and dependence dynamics. Drawing from fairness heuristic theory, this study extends previous research by investigating the role of fairness in affecting compliance and long-term relationships. The authors observe the contingent effect of fairness along various levels of distributor dependence. In the context of a naturally occurring program, the authors collect data from a focal manufacturer's distribution channel and find that (1) fairness perceptions have significant impacts on both compliance and relational outcomes, (2) the efficacy of program fairness declines as distributor dependence increases, and (3) distributor dependence increases the effect of economic incentives on compliance. The authors discuss the theoretical and managerial implications of these findings.     

Contractual arrangements between farmer cooperatives and buyers in China

The agrofood market in China is dominated by spot market exchanges of small farmers and various small traders, with only minor penetration of the modern supply chain at the farmgate. The emerging Farmer Professional Cooperatives (FPCs) are expected to facilitate vertical coordination. The overall goal of this study is to investigate the contractual arrangements between the FPCs and the buyers. Based on a national representative survey of 157 FPCs in China, this study shows that 32% of FPCs introduced written contracts in the primary marketing channel. Contracts are more likely to be adopted in the livestock sector and are positively related to the scale of production. While branding promotes contracts between FPCs and buyers, public certification of quality and food safety often substitutes for contracts. Furthermore, the membership heterogeneity of FPCs affects an FPC’s decision to use contractual arrangements with the buyer.     

长江经济带生态环境保护与经济高质量发展的耦合协调关系及其影响因素

以长江经济带为研究地区构建生态环境保护与经济高质量评价指标体系。利用耦合协调模型、Dagum基尼系数、核密度和固定效应模型探究耦合协调度的时空特征、区域差异、动态演进特征及影响因素。结果表明：1）2008-2020年两系统发展指数均呈上升趋势。2）耦合协调度仍处于较低水平,具体表现为沿海下游省市>中心省市>上游省市。3）区域间差异是总体差异的主要来源,并且绝对差异缩小,梯度效应减弱。4）经济发展水平、人口聚集程度、产业结构升级和城镇化水平对耦合协调发展具有显著影响。     

MAP算法在Turbo码译码中的应用和研究进展

对Turbo码译码算法进行了综述,包括SOVA、MAP、LOG-MAP、MAX-LOG-MAP等算法,并对这几种算法进行了比较。同时根据近年来对Turbo码译码算法的研究,对几种新的译码算法进行了介绍和讨论。     

渠道理论中的"相互依赖"新模式--一个跨学科的研究框架

尽管渠道理论研究的焦点在不断转移--从渠道"效率和效益"转向渠道"权力和冲突",再到以渠道"关系和网络"为重心,但"相互依赖"始终都是一个核心的基础性概念.本文在跨学科的视野下,借用相对成熟的国际关系理论,阐明了渠道"相互依赖"关系新模式:渠道中的相互依赖通常都表现出非对称性,这影响着关系规范的安排;相互依赖的脆弱性是影响关系成员采取行动的关键因素;构建和谐的渠道关系的途径是走向"复合相互依赖",即渠道成员之间的多渠道联系、各个问题没有等级之分、(威胁)退出关系不发生作用.     

我国会计制度与企业所得税法规差异协调策略

税收从产生之日起,就与会计联系在一起。随着人类社会经济的发展,税收与会计的联系更加紧密,它们相互作用、相互影响,在社会经济生活中发挥着越来越大的作用,并成为经济学的两个重要分支。会计制度与税收的处理不仅是税务部门与企业的重要工作,而且对整个社会的经济发展也有着重要的影响,如何处理会计制度与税法之间的关系,既是会计制度和税收制度设计的理论问题,又是征纳双方确定征纳税额和反映会计信息的实践问题。在新的税法出台和新的会计准则实施后我国会计制度与企业所得税法规差异的协调更有意义。     

区际产业转移的影响因素及对策分析

区际产业转移,是解决我国区域协调发展问题的重要途径。然而,市场经济条件下的区际产业转移往往受到生产要素、区位、市场、制度等因素的影响。因此,要加快区际产业转移,必须针对这些因素制定相应的对策。     

废旧电器再生利用价格形成与运行机制研究

废旧电器回收再生利用产业化具有广阔前景和重大意义,但产业链价格理论与形成机制不完善制约着产业健康发展。废旧电器回收再生利用价格形成与运行机制研究应以产业链协调发展为原则,政府管制为驱动力。用循环经济理论。兼顾我国现阶段废旧电器的垃圾和商品两个属性,从技术、经济、社会3个层次研究其回收再生利用物质、价值和行为3个形态循环机理与互动关系;从生产者延伸制出发研究产业链各主体责任体系与运行机制：以产业链有效运行为目的,研究特许经营下再生利用补贴政策与实施机理,形成政府产业价格调控与管制方法,构建产业发展科学评价体系,形成价格市场竞争与合理补贴系统理论．提供产业可持续发展决策依据。
