On the Geometry of Constant Returns

Imports are modeled as a fixed proportion of spending rather than as a function of total or disposable income. With this formulation, the import component of spending shifts must be netted out in order to predict the initial autonomous change in domestic spending. In addition, the formulation should provide a clearer understanding than current formulations of how leakages influence the multiplier process.     

旅游产业集群成长阶段及持续成长驱动力分析——以杭州国际旅游综合体为例

论文把旅游产业集群成长阶段分为孕育阶段、快速成长阶段、逐步成熟阶段及稳定阶段。论文以杭州国际旅游综合体为例,对旅游产业集群持续成长驱动力进行了分析,认为：旅游要素比较优势为旅游产业集群持续成长的基础驱动力;强劲的旅游投资是旅游产业集群持续成长的保障性驱动力;完善集群网络是旅游产业集群持续成长的关键驱动力;集群创新是旅游产业集群持续发展的核心驱动力;强有力的旅游产业集群基核吸引力促进旅游产业集群持续成长;旅游者的消费需求偏好是杭州国际旅游综合体持续成长的需求驱动力。     

模块化全球生产网络与我国战略性新兴产业嵌入发展

认为模块化全球生产网络的演化是一个一体化—模块化—修正调整—一体化的循环过程,分析了该网络中存在的两类入围竞争以及瀑布效应的形成。在此基础上,提出我国战略性新兴产业嵌入发展应实现的四重转变:从低端的点嵌入转向高端的系统嵌入;随着网络演化阶段的推进实现动态性嵌入发展;从被动单向参与国际分工转向主动双向嵌入发展;从后发嵌入发展转向先发嵌入发展。     

基于SWOT分析的成都“一市两场”定位探讨

通过对成都地区近10年的航空运输规模以及“一市两场”发展现状进行分析,提出成都地区两个机场进行功能定位的必要性。运用SWOT模型分别分析成都双流和天府机场发展的优势、劣势、机遇和挑战,并建立SWOT分析矩阵提出对策和建议。最后对两机场的发展策略进行对比分析得出：天府机场定位为成都国际航空枢纽的主枢纽,是服务成渝城市群的核心机场,重点打造国际客货运航空枢纽;双流机场定位为区域航空枢纽,主要运营国内商务航线和地区航线,保障国际公务航空业务和国际备降航班。     

基于数据挖掘的国际货代企业客户订单行为分析

国际贸易的突飞猛进,赋能进出口货物运输的蓬勃发展。国际货运代理企业作为进出口货物运输的无船承运人,如何保证日常订单稳步增长将面临新的机遇和挑战。选取客户订单行为分析作为数据挖掘业务目标,设计了数据挖掘流程。以D公司业务数据为例,选择关联规则数据挖掘方法开展具体的数据挖掘展现,发现订单交易中不同商品之间存在的关联规则并应用于国际货代企业客户关系管理决策实践,为其他同类企业开展具体业务数据挖掘应用提供参考和借鉴。     

中国CPI编制方法研究及国际经验借鉴——基于网络价格信息视角

CPI编制是宏观经济管理的重要内容,随着大数据等信息技术的发展,网络价格信息的采集与应用对CPI数据采集、计算、指数权重以及统计模式等方面都产生了不小的影响。与国际经验相比,中国CPI编制在权重更新频率、新产品偏误、季节性产品处理、自有住房服务处理以及特型CPI编制等方面都存在问题。应采取引进现代化的CPI数据采集、加快完善CPI权重设计方法、努力提升CPI统计质量、不断推进特型CPI指数编制等措施,利用网络价格信息不断优化中国CPI编制。

Mars or Mercury redux: The geopolitics of bilateral trade agreements

We analyse the role of economic and security considerations in bilateral trade agreements. We use the pre‐World War I period to test whether trade agreements are governed by standard gravity variables, or by instead—or in addition—geopolitical factors. While we like others find support for standard gravity variables, we also find that defence pacts boost the probability of trade agreements by as much as 20 percentage points. Our estimates imply that were the U.S. to alienate its geopolitical allies, the likelihood and benefits of successful bilateral agreements would fall significantly. Trade creation from an agreement between the U.S. and E.U. countries would decline by about 0.6 per cent of total U.S. exports.     

International joint ventures research on Africa: A systematic literature review,propositions, and contextualization

This study reviewed the research on international joint ventures (IJVs) in Africa up to 2017. The authors performed a systematic search of peer‐reviewed good‐quality research using the 6W procedure and ensured the quality of the review by using the 5Cs quality criteria. The content analysis was focused on four research questions. A total of 22 relevant studies were found. Overall, only about one‐third of the lead authors were affiliated with African universities. A majority of the studies were quantitative, and 78% of the studies were done for three countries: Ghana, Morocco, and Nigeria. There was either just one or no study on trust and conflict, partner selection, and human resource management (HRM). At the contextual level, it seems the most important factor influencing IJV strategy and success is institutions. We therefore suggest a greater use of institutional theory. Finally, we present a summary of conceptual framework and four propositions to guide future research.
