From peripheral to core: a case study of a 3D printing firm on business ecosystems reconstruction

ABSTRACT

The rapid development of emerging digital technologies is giving peripheral firm, which is participant in secondary and complementary positions in a business ecosystem, unprecedented opportunities to shape its own ecosystem. Prior ecosystem studies mainly focus on the perspective of core firm, while few taking the perspective of peripheral firms. Using the case of a leading 3D printing firm in China, this study adopts resource orchestration as theoretical lens and investigates how a peripheral firm developed its business ecosystem and became a core firm in its own digital ecosystem. Specifically, this study identifies three stages of ecosystem development and the detailed processes and mechanisms, respectively. It contributes to the literature by exploring the ecosystem dynamics from an understudied perspective and identifying the processes and mechanisms of peripheral firms developing its ecosystem towards digital ecosystem. It also sheds lights for peripheral firms in existing business ecosystems in their business strategy development.     

中国外汇储备适度规模实证分析

截至2007年底,中国外汇储备突破1.5万亿美元,建立计量模型对中国外汇储备规模进行实证分析表明：自2001年以来中国外汇储备实际规模一直大于适度规模。应扩大内需,酌情开征外汇交易税,适度进行汇率改革,以缓解外汇储备过快增长的局面。     

Managing the Monetary Consequences of Reserve Accumulation in Emerging Asia

Abstract

The huge increase in international reserve holdings by Asian countries since the 1997 crisis has been one of the most important recent developments on the international financial scene. These buildups have contributed substantially to concerns about the creation of excessive global liquidity. How justified these concerns are depends heavily on the extent to which the reserve accumulating countries have been able to sterilize the effects on their domestic monetary aggregates. We use a unified theoretical framework to undertake dynamic estimations of the magnitude of sterilization and offset coefficients (which measure the degree of capital mobility) for a large set of Asian economies. We find that despite substantial capital mobility there has been a high degree of effective sterilization to date.     

金融状况指数的理论设计及应用研究

考虑到当前金融状况指数（FCI）理论构建和指标选取存在的片面性,本文以产品市场均衡和货币市场均衡为切入点,提出将非人力财富比重作为重要因素纳入FCI的新观点。并针对每一个要素,均用验证性因素分析等方法从若干指标中筛选出代表性最佳的指标,再以VAR模型为赋权方法得到我国的FCI。通过与CPI的因果关联、动态分析以及与部分学者的研究成果进行比较,发现经过指标定量筛选后构建的FCI具有最佳经济效果,更符合中国现实。     

关于后发优势与中国中部地区工业化的思考

基于GRA&BPNN的广西粮食产量预测研究

[目的]研究粮食产量的影响因素并以其相关性为基础预测粮食产量对实现广西粮食产业的"做强做优"具有重大意义。通常情况下粮食产量与种植技术发展水平、农田耕地面积、土地肥力、气候等诸多因素相关,但是在样本数据不足、数据间关联度不明显的情况下则无法采用回归分析、灰系统等常用预测方法。[方法]文章应用灰色关联分析方法得到水库水量、农田有效灌溉面积、第一产业从业人口、播种面积、除涝面积等5个与广西粮食产量关系最为密切的因子变量,同时取2004~2012年的数据作为学习、训练样本,以2013~2014年的数据为试报样本,并以此建立BP神经网络粮食预测模型。[结果]检验结果表明运用本模型预测粮食产量具有较高的精度和良好的泛化性。[结论]根据模型结果,该文提出提升广西粮食产业发展的可行性建议,即加强水库的管理、引导与粮食产业相关的产业、稳定粮食种植面积、加强洪涝灾害的防御和治理能力、推进农业信息化。     

JOINT VENTURES IN CHINA: PROBLEMS AND SOLUTIONS

The author reviews problems associated with joint ventures in China and discusses new regulations designed (1) to give more decision-making rights to joint ventures, (2) to help reduce project expenses, and (3) to provide more loans for joint ventures' short-term revoling funds.

Internationalization Strategy of Chinese E-Business Companies

The e-business market has experienced a speeding development at emerging market. This research aims to identify the corporate-level factors that influence decisions of pursuing an internationalization strategy at e-business companies from emerging market, based on the study of Chinese e-business companies. The Probit model and General Estimation Equation (GEE) estimation are performed to analyze the effect of corporate-level factors on the decisions of internationalization strategy, and the Heckman selection model is further performed to analyze the sample selection of Chinese e-business companies in their strategic decisions. This research will be helpful to managers and administrators of e-business companies from emerging market.
