溢出效应和网络贴合度扰动下的二级供应链网络广告投放策略分析

为研究溢出效应和网络贴合度扰动下,二级供应链的网络广告投放策略问题,以强势制造商和两个网络零售商组成的二级供应链为研究对象,考虑产品的网络贴合度和网络广告计费特征,构建基于溢出效应的期望需求模型,通过博弈论方法给出了完全不合作、合作、半合作、战略联盟等4种模式下的均衡解,并对以上4种均衡结果进行比较分析。研究结果表明:无论在何种模式下,制造商批发价格与产品的网络贴合度成反比;固定位网络广告投资额和网络广告投资总额与产品的网络贴合度成正比,固定位网络广告投资额与溢出效应成反比;合作状态下的利润总额通常情况下较低;当产品的网络贴合度超过一定阈值范围时,采用战略联盟使得供应链成员利润最大化。     

Understanding value creation in closed loop supply chains – Past findings and future directions

The topic of value creation through the recovery of returned products in closed loop supply chains is scattered across various bodies of literature. We undertake a systematic literature review of 144 articles in relevant green, reverse and closed loop supply chain literature to synchronize existing knowledge on value creation. Value manifestations of four types of value, namely economic, environmental, information and customer value, are identified. Value adding concepts from the forward- and reverse supply chain may leverage the process of value creation. They are classified into six subclasses, namely partnerships and collaboration, product design characteristics, service concepts, IT solutions, supply chain processes and organizational characteristics. We present a conceptual framework on a strategic level. In this way companies can create competitive advantages by closing the loop. The results of the literature analysis suggest avenues for future research on the operational and strategic level.     

考虑交叉销售的O2O供应链合作广告策略研究

基于网络零售平台与制造商的合作广告实践，运用Stackelberg博弈理论研究了平台交叉销售效应及合作广告引导作用对O2O供应链合作广告决策的影响，并通过数值算例对参与合作广告计划前后渠道成员的决策变量均衡结果和利润进行对比分析，研究发现平台交叉销售效应是影响网络零售平台合作广告计划制定和实施的关键因素，只有当其达到一定水平时，制造商才拥有参与网络零售平台合作广告计划的资格；在一定条件时，合作广告计划能够实现制造商和网络零售平台利润的提升；当平台交叉销售效应较大时，网络零售平台获得的利润大于制造商。     

Is open innovation always the best for SMEs? An exploratory analysis at the project level

Open innovation (OI) projects are increasingly adopted by small‐ and medium‐sized enterprises (SMEs). Yet, undertaking OI is not only a source of opportunities for SMEs as it can, at the same time, present risks. How SMEs manage the balance between the potential benefits and the emerging challenges of OI is still an overlooked topic in the literature. Using evidence gathered through multiple case studies and drawing upon the relational view of the firm, we explore how and why value creation opportunities and different managerial challenges emerge for SMEs pursuing OI projects. We analyze different stages of OI projects in several different contexts of their implementation. Our analysis sheds light on the different nature and dynamics of knowledge involved within OI projects as important boundary conditions affecting successful search paths, learning processes, and the development of appropriability mechanisms. By offering a contextualized view of OI in SMEs, this study also provides insights to business managers on the situational opportunities and constraints of OI, including managerial suggestions on actions to manage tensions within differing OI projects.     

Value drivers of blockchain technology: A case study of blockchain-enabled online community

There is growing recognition that blockchain technology has significant potential to alter how organizations and people work and communicate. However, theoretical guidance concerning how organizations leverage blockchain technology to enhance value creation for users is still limited. Grounded in the socio-technical perspective and leveraging the rich data obtained from case analyses of blockchain-enabled online communities, this paper develops a theoretical model to identify the core value drivers that blockchain enables for online communities. The core value drivers include: a reputation-value system, data ownership mechanisms, and verification & tracking mechanisms. Our findings suggest that these three value drivers enhance value creation of online communities by motivating participation and protecting contributions.

桥梁工程：科学、技术和工程

桥梁工程学科包括科学研究、技术发开和工程建造。桥梁科学研究的最高目标是科学发现,发现客观存在的规律和问题必须站在前沿,近3年研判出的5项研究前沿和五项开发前沿值得思考;桥梁技术开发的最高目标是技术创新,创新主观需要的工具或方法,必须旨在增值,二次大战后60年以3项桥梁核心技术为代表的60项创新技术发挥了重要作用;桥梁工程建造的最高目标是工程创造,创造客观没有的结构或构件,这必须存在需求,新世纪20项IABSE杰出结构奖造就了18项工程创造和17项技术创新。桥梁工程的未来必然朝着长寿命、特大跨、超深水、多灾害、全信息和可持续等方向发展。

环境、情感、文化“嫁接”与建筑创作

西南是中国西部乡土建筑众多的区域,文化的积淀是多彩的,它对现代化新建筑创作、对乡土建筑文化的发展有着深远影响和坚实的根基,本文依西南乡土建筑文化,引东部民间建筑及国外建筑,通过对建筑文化及环境、情感的探讨,进而说明建筑创作应立足于本土建筑文化,同时与外来优秀建筑文化、思想观念“嫁接”,必然产生积极后果。建筑创作应是环境、情感及文化“嫁接”三者关系的产物,是方法,又是原则。
