新世纪亟待发展职业技术教育

经济是基础,而教育更是发展国民经济基础的基础,现代国际的竞争是经济的竞争,生产力的竞争,说到底还是人才教育的竞争,因此,要使我国经济持续增长,必须依靠教育.我们深知,二十一世纪是一个知识经济的时代,教育是牵引中国走进知识经济时代的发动机,在农业社会和工业社会曾起过重要作用的生产要素即劳动力、能源等不再成为推动经济增长的主要因素.教育本身作为知识生产和再生产的阵地,必然是未来经济增长的主要因素.纵观发达国家,以高科技为基础的知识经济证明,国家要想跟上世界经济发展的主流,并保持国际竞争能力,不仅需要一个具有战略意义的国际信息网络和一个在运作模式上同国际经济发展主流接轨的文化知识产业体系,而且需要有能够使知识有所创造、加工、传播,职业性知识与技术应用有机结合起来的体系.     

Beyond absorptive capacity in open innovation process: the relationships between openness,capacities and firm performance

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications.

HOW LARGE ARE LEARNING EXTERNALITIES?*

The quantitative features of human capital externalities are not fully understood. Although static externalities are estimated in some studies, learning externalities remain mostly unestimated. By calibrating a growth model, this article provides an estimate of learning externalities. The calibration uses an equilibrium condition that equates private returns on physical capital and human capital. The results suggest that sizable learning externalities exist, even in a conservative setup. The estimated social rate of return on human capital is 9.0%, compared to the private rate of return, 6.6%. Therefore, human capital externalities are an important source of economic growth.

Currency Networks, Bilateral Exchange Rate Volatility and the Role of the US Dollar

We investigate monthly bilateral exchange rate volatility for a large sample of currency pairs over the period 1999?C2006. Pegs (particularly to the US dollar) and managed floats tend to have lower volatility than independent floats. A deeper investigation shows that the peg effect operates almost entirely through currency networks (i.e. where two currencies are pegged to the same anchor currency), and the lower volatility of US dollar pegs reflects the size of the US dollar network. Managed floats show clear evidence of tracking the US dollar, further increasing the effective size of the US dollar network. Inflation undermines the currency-stabilizing effect of peg networks. Currencies in smaller peg networks have higher unweighted but not trade-weighted exchange rate volatility, which is consistent with anchors being chosen to minimize trade-weighted volatility. The size of the effective US dollar network revealed here is a plausible explanation of the rarity of basket pegs. Volatility also reflects a range of structural factors such as country size, level of development, population density, inflation differentials and business cycle asymmetry.     

创业者因“我能”而拼凑：创业震荡的调节效应

遵循自我一致性理论和认知评价理论，引入创业目标清晰度和创业震荡（消极创业震荡和积极创业震荡），揭示创业自我效能感影响创业拼凑的内在作用机制和边界条件。基于297名创业者回溯式调查数据进行实证检验，结果发现：创业自我效能感既能直接促进创业拼凑，又能通过创业目标清晰度的中介作用产生间接促进作用；积极创业震荡能够削弱创业自我效能感对创业拼凑的驱动效应，并且通过创业目标清晰度的中介作用实现；消极创业震荡的调节效应不显著。研究结论部分解释了“面对同样的资源短缺情境，为何有些创业者积极开展创业拼凑，但有些创业者却无所事事”和“积极创业者在何种情境下会开展更多创业拼凑”等问题。
