县域农业劳动力转移配置效应的实证研究——以江苏省县域为例

农业劳动力转移对于经济的增长具有非常重要的配置效应,但是不同经济层面的研究会对这一问题产生不同的结论,县域农业劳动力转移对于县域经济增长的配置效应便存在着较大的差别。本文以江苏省县域经济发展为例,建立了江苏省县域总体、江苏省三大区域县域、江苏省各县域三个不同层面的实证分析框架,对近20年间县域农业劳动力转移配置效应进行了实证分析。本文的创新点在于,20年间江苏省县域总体和三大区域县域的农业劳动力转移配置效应呈现出倒"U"型发展趋势。县域农业劳动力转移在前10年的配置效应要大于后10年。苏南县域呈现出更高的农业劳动力转移配置效应。基于此,本文提出了相应的政策建议。     

Empirical Analysis of International Competitiveness of China＇s Industry After A Decade of WTO Accession

本文利用最新的统计数据对中国加入WTO十年以来产业国际竞争力的现状及变化趋势进行了实证研究,得出如下结论：加入WTO十年以来,中国产业国际竞争力有较大程度提升。虽然中国传统劳动密集型产业比较优势在下降,而技术和资本密集型产业比较优势在上升,但中国目前最具有比较优势的产业仍是劳动密集型产业;中国劳动密集型、技术密集型和资本密集型产业的竞争优势都有所提高;中国制造业竞争优势的增强是推动中国产业国际竞争力提升的主要动力,中国传统劳动密集型产业仍然保持着较强的国际竞争力,同时一些技术和资本密集型产业的快速发展推动中国产业国际竞争力不断提升。虽然中国制造业产业国际竞争力的进一步提升面临着诸多挑战,但本文判断中国产业国际竞争力处于第二次快速提升的前夜,从中短期来看,2016年“市场经济地位”的自然获得,将会进一步释放中国产业国际竞争力的既有优势;而从中长期来看,随着人口素质的不断提升,中国将迎来质量型人口红利所带来的新的20年战略机遇期,这将是中国产业国际竞争力持续提升的重要源泉。     

A comparison of revenue growth at recent-IPO and established firms: The influence of SG&A, R&D and COGS

A dynamic view of the resource based theory (RBT) examines how a firm builds its resources over time, considering variations in resources' growth rates while the firm attempts to grow. Accordingly, we consider the elasticity of accumulated resources to assess conditions where these resources might serve as substitutes for rather than complements to COGS during periods of growth. We specify a production function that links aggregate resource allocation among SG&A, R&D and COGS expenses to a firm's revenue. This function yields a set of hypotheses on the elasticity of SG&A and R&D, and the productivity of COGS, while controlling for the revenue growth rate. We test these hypotheses on a dataset of 64 randomly selected firms that recently underwent an IPO, and a comparable set of 64 established public firms from four high-technology sectors. Results show that the accumulated stocks of resources can serve as substitutes for rather than complements to COGS, and the manner in which recent-IPO firms allocate and use resources differs from their established counterparts. We discuss the implications of associated elasticity and productivity results.     

我国对外直接投资主要宏观影响因素的实证研究

影响一国对外直接投资的宏观经济因素很多,不同的国家或经济体、不同的宏观因素对对外直接投资的作用程度并不相同。本文针对我国的经济现实,主要以我国对外贸易、资源需求、工资水平为影响我国对外直接投资的主要宏观解释变量,利用1993-2006年的数据进行计量分析。结果显示,对外贸易、资源需求、工资水平因素都对我国对外直接投资有显著的影响。本文还分析了产生这种结果的可能原因并提出了相应的建议。     

外商直接投资对山东省经济增长的影响分析

分析了山东省利用外商直接投资(FDI)的现状及特点,采用1985-2006年的山东省年度经济数据,运用协整检验(Co-integration Test)和Granger因果分析方法,通过实证分析表明:外商直接投资对山东省经济的增长是有促进作用的,但这种促进作用有限。进一步分析了造成这种现象的原因以及为更好地发挥外商直接投资(FDI)的促进作用应采取的对策。     

服务贸易与中国经济增长影响机制实证研究

本文旨在就服务贸易与经济增长的影响机制进行实证研究。中国改革开放以来的经验数据,证实了服务贸易通过增加人均资本、加快制度变革进程对人均产出产生正面影响。但是,服务贸易进口与出口的经济增长效应相互不平衡,并且总体上落后于货物贸易。而实证检验中所发现的人力资本、技术进步功能的偏离,为完善中国服务贸易发展机制提供了理论依据。     

Determinants of Store Brand Share

Private labels or store brands have witnessed considerable growth in the last few decades, especially in grocery products. However, market shares of store brand vary considerably across categories, markets, and countries. A natural question of interest to academics and practitioners is what factors influence store brand market shares. Drawing on a utility framework, we develop 21 consumer, manufacturer, retailer, and product-market characteristics that can influence store brand share. We test the empirical generalizability of the effect of these determinants through a meta-analysis of data from 54 individual and aggregate market studies. Twenty of the 21 determinants show significant, empirically generalizable effects. We discuss the key findings, their implications, and directions for future empirical research.     

Going for gold: Investigating the (non)sense of increased advertising around major sports events

Major sports events draw unsurpassed media attention. Companies are motivated to increase their advertising investments around these events to reach large audiences in a short period. Is such an advertising surge actually beneficial though, or should companies avoid advertising in these periods because of negative effects of competitive interference? This study investigates when consumer packaged goods companies should invest in advertising to increase sales: before, during, or after the event or outside these event periods. The author estimates short- and long-term own- and cross-advertising elasticities for 206 brands using four years of weekly data. Although considerable heterogeneity exists across brands, own-advertising effectiveness diminishes especially before and during major sports events, in both the short and the long run. In addition, brands benefit less from category-demand effects through competitors' advertising. Conversely, greater increases in advertising spending resulting in significant growth in share of voice around focused, single-sport events are a successful strategy to overcome this overall general negative trend.     

中国价格贸易条件变动趋势与出口商品结构——基于1981-2007年的时序数据的研究

利用回归方程对1981-2007年中国贸易条件变动趋势进行测算,研究发现:中国贸易条件以每年4.6%的速度下降,其中工业制成品贸易条件下降是主要动因。在此基础上,利用协整模型对价格贸易条件与工业制成品出口比例的相关关系进行实证检验:长期来看,价格贸易条件与工业制成品出口比例之间存在着稳定的协整关系,并且工业制成品出口比例上升是造成中国价格贸易条件恶化的格兰杰原因。     

Outsourcing of Information Systems Functions in Small and Medium Sized Enterprises: A Test of a Multi-Theoretical Model

In this paper determinants of information systems (IS) outsourcing are deduced from transaction cost economic theory, resource-based theory and power theory. They are summarized in a theoretical framework which is tested using a sample of small and medium sized enterprises (SMEs) in Germany. The results show that internal performance and know-how deficits vis-à-vis external service providers are key determinants that explain why different IS functions are outsourced to varying degrees in SMEs. Moreover, the determinants of IS functions were found to partially differ between IS functions. Revised reprint of an article from WIRTSCHAFTSINFORMATIK 43(4)2001:339–350.
