基于标准数据的创新程度提升路径研究

创新程度在资源配置中的作用日趋明显，但目前创新程度常以专利作为测量值。随着标准在产业发展中引导性增强，作为创新重要产出的标准在创新程度提升中的地位日渐凸显。提出一个以标准数据为依据，通过对标准创新程度值的测量，结合国际国内创新程度四分图模型，研究具体领域创新程度提升路径。以信息技术应用领域标准为分析对象，结合国际标准化组织颁布标准和中国标准，确定信息技术在各应用领域创新现状。结果显示：信息技术在办公系统和银行业务两个领域应用的国际国内创新程度都很低，应在完成产业升级后逐渐淘汰；其在健康关怀领域应用的国际发展前景良好但国内创新程度很低，是重点研究领域。随后，对信息技术在健康关怀领域应用的国际和国内标准具体内容进行对比分析，发现中国与国际发展存在差距，并以国际国内创新程度为依据对位于四分图不同区域的信息技术应用领域创新程度提升提出合理建议。     

Stock replenishment policies for a vendor-managed inventory in a retailing system

Using Vendor Managed Inventory (VMI), the vendor determines the replenishment decisions at the location of buyers (retailers). This strategy is used primarily for handling demand fluctuations stemming from the Bullwhip effect, leading the system to prevent from holding excessive inventory that result in a reduction in the overall cost of the supply chain. The main advantages of VMI for vendors are higher levels of accessibility to inventory information and more direct contact with the customers. Similarly, VMI has some pros for the buyers, such as shared risk with upper levels of supply chain and reduction in their holding costs of inventory. In this paper, a vendor-managed inventory system is developed containing one vendor and two buyers in which the main assumption is that back-ordering and lost sales are permitted. In this system, (r, Q) and (R, T) replenishment policies are compared according to their performances to see which one performs more cost-efficiently when partial back-ordering is allowed. In accordance, mathematical models utilizing (r, Q) and (R, T) replenishment policies are developed, and algorithms for deriving the optimal replenishment decision variables are proposed. Moreover, significant differences between the two replenishment policies are discussed. The main finding obtained by this research is that when shortage is permitted, both (r, Q) and (R, T) replenishment policies under VMI have pros and cons in different contexts.     

基于组态视角的众创空间创客集聚机制研究

以江苏省383家众创空间为样本，应用组态思维和QCA方法整合资源与服务两个层面的6个条件，探讨形成众创空间创客集聚差异的多重并发和复杂机理。结果发现：①众创空间高创客集聚存在服务主导型、场地-创客教育主导型、全要素型3个组态，其中，服务主导型、场地-创客教育主导型能深层次、强有力地影响众创空间高创客集聚；②众创空间非高创客集聚存在单纯地产式、单纯线下投资促进、单纯线上投资促进3种组态，且对众创空间非高创客集聚的影响基本相当；③资金资源不充足、场地资源不充足与人员服务不充足在解释非高创客集聚时具有替代作用。     

Relief aid stocking decisions under bilateral agency cooperation

We aim to quantify the benefits of cooperation between humanitarian relief agencies in terms of stocking decisions. We consider two agencies that stock the same type of relief item at different locations prone to individual disaster risks and agree to transship the shortage amount from available stocks in case of a disaster. We incorporate the disaster risk to the Newsvendor model by conditioning the stock quantity decisions on the event that a major disaster occurs within the lifetime of the stocked relief item. We optimize the stock quantity for each agency in response to the other's quantity and compute a Nash Equilibrium solution numerically. We apply this game theoretic approach to the case of earthquake preparedness in Istanbul to optimize the stocking decisions of an agency for shelter units in cooperation with another agency. We investigate the characteristics of the solutions under various parameter settings and identify cases in which cooperation may be beneficial to one or both of the agencies.     

Non-linear Gaussian sovereign CDS pricing models

Prior literature indicates that quadratic models and the Black–Karasinski model are very promising for CDS pricing. This paper extends these models and the Black [J. Finance 1995, 50, 1371–1376] model for pricing sovereign CDS’s. For all 10 sovereigns in the sample quadratic models best fit CDS spreads in-sample, and a four factor quadratic model can account for the joint effects on CDS spreads of default risk, default loss risk and liquidity risk with no restriction to factors correlation. Liquidity risk appears to affect sovereign CDS spreads. However, quadratic models tend to over-fit some CDS maturities at the expense of other maturities, while the BK model is particularly immune from this tendency. The Black model seems preferable because its out-of-sample performance in the time series dimension is the best.     

Club convergence and drivers of digitalization across Indian states

Disparity in the level of digitalization is a crucial driver of economic inequality in an economy. Although a pocket of its population is still bereft of the benefits of digitalization, India currently has the second highest number of internet subscribers in the world despite the nation's late adoption of digital technology. An accurate assessment of the current state of digitalization in the country is required for devising effective initiatives towards building a Digital India and bridging the nation's internal digital divide. Considering 17 major Indian states and 21 variables for 10 years, we constructed a composite index of digitalization with the help of Principal Component Method (PCM). This paper identifies factors responsible for the digitalization divide across states. In the second part of the analysis, the study confirms, with the help of club convergence test, the absence of overall convergence towards digitalization and the existence of the non-convergent group. This paper also shows that the non-convergent group of states are at the bottom of the ranking table which indicates the need for greater attention to initiatives to bridge the digital divide.     

“强监督”还是“搭便车”：自然人大股东如何影响企业专利质量

通过构建改进的知识宽度法测算企业专利质量，并以2007—2016年中国沪深A股上市公司为样本，分析自然人大股东对企业专利质量的影响以及在不同类型企业中其作用的差异性。结果表明，作为“强力监督者”，自然人大股东能够促进企业专利质量提高。但因为其角色由“强监督”转变为“搭便车”，故这种促进作用在国有企业和具有政治关联的企业中并不存在。进一步研究表明，促进作用是通过加强对经理人和研发人员的监督，减少其控制权下投机性创新策略，提升其工作努力程度实现的。研究结论为促进国有企业与民营企业创新能力提升提供相应的政策启示。

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.     

数字经济、城市创新与区域收敛

当前，数字经济蓬勃发展，数据已成为除劳动、土地和资本等传统生产要素之外的新要素，能否依托数字经济发展赋能城市创新？文章在对数字经济的概念和内涵进行基本界定后，借助微观大数据构造的"互联网+数字经济"指数，实证分析了2015-2018年中国283个地区数字经济发展对城市创新及创新差距的影响。研究结果显示，数字经济发展能够显著促进城市创新水平提升。其中，人力资本集聚效应和创业活力增强效应是数字经济赋能城市创新的两条重要路径。在替换被解释变量、消除样本选择偏差、选择分位数回归，以及创新性地采用各地级市市长过去修习的专业作为历史工具变量检验后，这一结论依然稳健成立。进一步空间杜宾效应分析表明，数字经济发展具有显著的空间溢出效应特征，不仅促进了本地区创新水平提升，而且对相邻地区的创新产出也产生了实质性影响，有利于缩小区域创新差距，实现区域创新收敛。此外，相较于实用新型专利和外观设计专利，数字经济发展对城市发明专利的影响更显著，说明数字经济发展推动的创新是真正意义上的质量创新而非策略创新。文章为评估数字经济发展的影响效果提供了理论依据和经验支撑，也为理性看待数字经济、防止出现数字鸿沟，实现区域创新均衡发展提供了有益启示。
