系统性金融风险的历史考察与防范对策

深入学习习近平在中国共产党第十九次全国代表大会上的报告，在考察20世纪以来的12次金融危机的基础上，对系统性金融风险发生的根源进行了研究，并结合我国当前系统性金融风险面临的形势，提出了防范系统性金融风险的对策建议。研究表明，将过去100多年引发金融危机的系统性金融风险的根源与我国当前的金融形势进行比较分析，可以发现我国面临的系统性金融风险形势十分严峻，必须在党的领导下，采取打击金融腐败、适当收紧货币政策、完善金融监管体系、维护币值稳定、加强金融科技监管等相关政策来防止系统金融风险的发生。     

学术印记、网络惯例与大学衍生企业产业嵌入

在大学衍生企业创业实践中，与产业主体间缺乏合作默契已成为大学衍生企业向产业网络嵌入的重要阻滞因素。针对该问题，基于网络惯例新视角，从大学衍生企业学术创生背景带来的异质性入手，构建“学术印记—网络惯例—产业网络嵌入”作用模型，探索技术动荡性的调节效应。运用多元回归分析等方法，对379家大学衍生企业调研数据进行实证检验。结果表明，大学衍生企业学术印记对网络惯例建立具有积极促进作用。同时，在向产业嵌入过程中，网络惯例对产业网络嵌入两个维度的作用机制存在差异，与结构嵌入存在倒U型关系，但正向促进关系嵌入。技术动荡性在“学术印记—网络惯例—产业网络关系嵌入”关系中具有正向调节作用。

新中国70年中国农村社会保障制度的演进逻辑与未来展望

新中国成立以来,得益于我国综合国力的快速提升和中国特色社会主义的制度优势,我国农村社会保障事业取得了巨大成就,但仍存在社会保障制度城乡不均衡发展等重要问题。本文依据多源流模型和公共产品理论构建了我国农村社会保障制度演进的分析框架进行分析表明,我国农村社会保障制度演进大概经历了制度萌芽与停滞、恢复与探索、改革与发展、完善和提高四个阶段,人民日益增长的美好生活需要、党和国家"以人民为中心"的发展理念、政策试点与政策研究、经济体制改革与综合国力提升共同构成了农村社会保障制度演进的动力机制。针对农村社会保障制度演进面临的重要挑战,提出了加强农村社会保障治理体系现代化建设等未来展望。     

畜牧产业结构变动对我国粮食安全的影响分析

［目的］改革开放40多年来，我国畜牧产业结构不断调整和优化，其生产供给结构与消费需求结构的变动与我国粮食安全问题息息相关。［方法］文章基于改革开放40多年来畜牧产业发展历程，从供给与需求两个维度分析我国畜牧产业结构变动的特征，并进一步探究畜牧产业结构变动与我国粮食安全间的作用机理，最后运用灰色关联度分析法实证其关联影响度。［结果］我国畜牧产业结构由耗粮型为主向节粮型转变，畜产品供给结构趋于合理，但不同区域间存在较大差异； 我国居民对畜产品消费需求量增加，但城乡居民畜产品消费结构及变动存在一定差异性； 畜牧产业结构变动与粮食安全有重要联系，畜牧业发展同保障国家粮食安全并不矛盾，畜牧产业结构变动主要通过耕地、基于口粮替代的食物需求结构变化及饲料粮需求3个方面作用于粮食安全； 具体来看，粮食播种面积、耗粮型畜产品比重和耗粮型畜产品饲料转化率对粮食安全水平的关联影响较大，节粮型畜产品比重与节粮型畜产品饲料转化率对粮食安全水平的关联影响小于耗粮型畜产品的影响。［结论］不断提高不同畜产品的饲料转化率，加大非粮型饲料资源开发利用度，推广非粮饲料应用技术，加快畜牧产业转型升级，满足消费者需求和保障国家粮食安全。     

The impact of RFID adoption on donor subsidy through for-profit and not-for-profit newsvendor: Implications for Indian Public Distribution system

Subsidy programs are sponsored by government and international agencies to improve affordability and accessibility of food and health products for socially deprived community. Although the donors in such programs allocate substantial resources to fund subsidies, a lot of it is wasted due to the inefficiency in the system arising out of product shrinkage and misplacement. This study analyzes the impact of private participation and advanced technology like RFID adoption on the donor subsidy under target consumption level. We formulate the problem as a donor funding the subsidy program through for-profit/not-for-profit newsvendor and compare the equivalent subsidy per consumption with and without RFID. We perform numerical analysis, collecting data from the public distribution system of India, and the results indicate that, unless the for-profit firm operates under a substantially reduced level of shrinkage and misplacement, the donor should always prefer a not-for-profit firm for program implementation. We also observe that among all the scenarios, a not-for-profit firm with advanced technology like RFID requires minimum donor subsidy to generate the target expected consumption.     

Policies for managing peak stock of food grains for effective distribution: A case of the Indian food program

The Indian food program has encountered a significant shortfall in storage due to slow expansion of storage facilities in comparison with procurement. The open storage of food grains results in substantial loss and deterioration of quality. While increasing storage capacity is a viable but costly and time consuming option, the adoption of policies for peak storage reduction would go a long way towards effective food grains management. On this background, this study proposes policy adoption for peak storage reduction for effective inventory management. A dynamic simulation model was built by replicating the complex flow process and incorporating the process variability for finding the bottleneck and significant factors. It was found that steep wheat procurement is the critical bottleneck factor for peak storage requirements. Two practical and straightforward, yet effective policies are proposed from the few existing strategies for peak storage reduction owing to the constraints associated with the food program. With the actual data of the food program, reduction in peak stock was estimated for the recommended policies, including the operational cost saving in storage. The practical implications of these policies within the system were also discussed. Through peak reduction, the use of open storage can be significantly reduced, and this leads to better food grains management for effective food distribution.     

Subsidies under uncertainty: Modeling of input- and output-oriented policies

Agricultural subsidies play an essential role in agricultural and rural development in many developed economies. Countries have implemented agricultural subsidy policies with a focus on food security and environmental protection. Agricultural production is risky and uncertain, influencing the efficiency of agricultural subsidies. This study develops a theoretical framework to analyze the effects of production uncertainties on the efficiency of agricultural subsidy policies under the double constraints of food security and environmental protection. The basic model is investigated under six different conditions, and expanded research also is presented. Our models show that uncertainty, including output, cost, and price uncertainties, and technology conversion efficiency significantly affects the efficiency of agricultural subsidies. Under high technology conversion efficiency, output-oriented subsidies are appropriate for food security and environmental protection goals. Policymakers should take both uncertainty and production efficiency into consideration when choosing between input-oriented and output-oriented subsidy policies.

贵州有色金属产业集聚度与竞争力的实证研究

促进有色金属产业集聚是提升贵州省有色金属产业竞争力的主要途径之一，因而准确测度和把握有色金属产业集聚与贵州有色金属产业竞争力的关系是非常必要的。文章把贵州省放在西部九省中进行对比分析，选取区位熵反映有色金属产业集聚度，选择企业数量区位熵反映矿产资源产业区域集聚度，选取产业产值区位熵反映有色金属产业经济集聚度，而有色金属产业竞争力则选取产值利润率借以反映。具体实证数据均来源于西部9个省份的2013统计年鉴与2013年的中国有色金属工业年鉴。通过实证研究认为贵州省有色金属产业存在诸如区域集聚、经济集聚不足，产值利润率低下，产业集聚效应难以充分发挥等问题。最后提出提升贵州省有色金属产业竞争力的相关政策建议。
