中国经济增长的可能性:一种基于修正的索洛模型的估算

索洛模型这一经典的经济增长模型有它无可比拟的优点,但对于考察中国问题来说,也有一些内在缺陷.本文根据中国经济增长的特征事实,对索洛模型做出了一些修正,并据此对中国经济增长的可能性进行了重新估算.     

The Research of Supply Chain Management Resource Model

Considering the harder and harder competition among enterprises, this paper puts forward the Resource model of supply chain （RBV） to enhance competitive advantages, then analyses the source of supply chain competitive advantages and introduce the advantage formula. Finally, the rent contribution to supply chain management is explained in detail.     

Partnering模式中伙伴收益分配比例的确定

Using replication research for just-in-time purchasing construct development

Using replication research, the validity of the just-in-time purchasing (JITP) construct is established. Although empirical researchers have examined JITP over the last two decades, a consistent set of valid, reliable factors has not been used. The lack of valid construct is a barrier to hypotheses testing and meta-analyses on JITP. This study confirmed the validity of six JITP factors: top management commitment, employee relations, training, supplier quality management, transportation, and quantities delivered using two different data sets and testing the first- and second-order structure of the JITP construct. Content validity, reliability, unidimensionality, convergent validity, discriminant validity, criterion-related validity, and an invariant factorial structure of the JITP construct were empirically established.     

县域经济差异成因的空间统计分析——以云南省为例

基于新经济增长理论,采用空间计量模型、R软件和Moran指数对云南省各县域的经济增长的空间相关性进行了检验,运用空间计量模型对各县域经济增长的差异进行了空间计量分析。结果表明：云南省各县域的经济发展存在明显的正相关,影响云南省经济发展差异的主要因素有城镇化率、工业化、财政支出等。     

孵化器的商业模式与自身发展——典型案例分析

企业孵化器是创业企业成长的摇篮,其能为创业企业提供优质孵化服务的前提是自身的健康发展。本文从商业模式理论出发,对比剖析上海市运行良好的两个孵化器的目标客户、价值主张、价值链、动态能力和收支平衡模型,并探讨这两个典型孵化器如何通过整合社会资源服务创业企业。本研究揭示了孵化器对创业企业的价值源泉是其服务能为创业企业产生正向现金流,特别指出孵化器为创业企业提供融资能力与其孵化服务能力呈正相关,从而论证了孵化器本质是一个智力型服务机构,可自我持续发展的孵化器是一个能与创业企业、合作伙伴共赢共生的创新生态系统。     

Impact of Donald Trump’s tariff increase against Chinese imports on global economy: Global Trade Analysis Project (GTAP) model

Donald Trump’s presidential campaign contains several trade protectionism plans. This paper aims to analyze possible global impact of United States’ plan to impose import tariff increase against China. The GTAP model is implemented. The simulations present possible short-run effects of full-protection and manufacturing-only protection with appropriate retaliation response from China. The policy might lead to GDP, terms-of-trade, and welfare decline in United States and China; and an increase in trade balance for United States. Trade diversion pattern is observed in the simulation results, predicting shrinking bilateral trade between the two countries and increasing export toward their third trading partners.     

“德合”船基于MOSES软件的DP作业分析

结合“德合”船DP动力定位系统,以康斯博格DP吊重测试文件为基础,基于MOSES软件对DP吊重测试过程中船舶关键数值进行模拟分析。建立了基于Moses软件的船舶模型及计算模型,对吊重过程中船舶吃水变化进行分析,选择典型吃水给到水动力模型中计算DP动力响应。从计算结果可以看出,随着吊机受力增加,船舶吃水逐渐增加,DP系统输出功率明显增加且对应关系明显。此计算结果为“德合”船DP测试安全进行提供数据支持,该计算模型也可以为以后海上DP吊装作业积累数据经验并提供参考。     

Modelling distribution of aggregate expenditure on tourism

The aim of this article is to obtain a statistical distribution that describes the aggregate expenditure of tourists related to their length of stay at a given location. This distribution enables us to estimate two parameters simultaneously; one controls the length of stay and the other, the expense incurred. We propose two distribution models, for which closed-form expressions are obtained. Covariates are introduced in order to study the factors that affect the aggregate expenditure. The results obtained indicate that the models achieve a reasonably good fit, with and without covariates.
