The relationship between innovation and firm performance has been uncertain. In previous empirical tests of both causal directions of the organizational performance and innovation relationship, the temporal sequence of research designs has often been flawed. We meta-analytically test both temporal sequences of this relationship using 158 effect sizes from 55 empirical studies. We find that many empirical studies hypothesized one temporal sequence (e.g. innovation and future performance), but used data based on the opposite temporal sequence (e.g. past performance and innovation). Correcting the studies based on the actual temporal sequence used reveals that while the relationship between innovation and future performance is positive (based on economic rent-seeking), the relationship between past performance and innovation is less clear, especially when the study's framing is taken into account. Focusing on temporal sequencing suggests new research avenues on the organizational performance and innovation relationship.  相似文献

生态效率兼顾经济活动的生态效益和经济效益,在一定程度上反映了经济可持续发展水平,其综合评价有助于探索经济发展方式转变的路径。2003—2010年中国大陆31个省份的工业生态效率测度及趋同分析表明:我国工业生态效率普遍偏低,其省际差异和年际变化差异都较大,而且存在明显的生态效率趋同。为进一步改善我国各省的工业生态效率,既要广泛搭建技术转移平台以促进先进技术推广,还要大力提高落后地区的技术能力以促进先进技术的充分吸收和利用。  相似文献

Comparison effects have been studied extensively in many fields. In particular, existing operations management articles have discussed the impact of comparison effects on enterprises' production and pricing decisions. Research has also shown that consumers' purchasing decisions are primarily determined by three factors: product quality, selling price, and comparison effects. The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist’s production quality and pricing strategy for substitutable products. Results reveal the following: (1) Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model. (2) The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices. (3) When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products, the monopolist’s optimal choice in the second stage is to keep production quality constant and increase the selling price. Consequently, the number of buyers does not decrease because of temporal comparison effects. Therefore, the firm increases its revenue. (4) For the market with two substitutable products with quality differences, one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period. At this point, the consumption situation in the market is the same as that in the first stage. Therefore, when no external constraints exist, the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage. (5) When consumer identity information can be confirmed in the market, social comparison effects, similar to temporal comparison effects, could help the enterprise increase its price and profit while maintaining product quality. These social and temporal comparison effects constrain consumers. Thus, the number of people who continue to buy products does not decrease.  相似文献

In connection with the housing market, which is presently raising a great deal of concern among the general public, this paper investigates regional housing prices in Spain using variable co-integration techniques. It analyzes the asymmetric behavior in real house prices among the Spanish regions focusing on the study of the long-term relationships over time. This paper raises an important question of the national averages masking important regional asymmetries. Results indicate evidence of co-integration, which suggests a broad grouping of regions based on physical proximity or similar economic characteristics.

Given its significant technological advantages compared to analog broadcasting, digital television (DTV) will be the television system of the future. However, it requires a full replacement of analog television sets by digital receivers, as DTV can only be watched with special equipment. In order to make this transition happen smoothly without losing the analog television audience, both signals have to be simulcasted until a substantial coverage with DTV broadcasting has been achieved. Australia and the US meanwhile have established a regulatory framework to lead this transition towards the end of analog broadcasting, the so-called analog switch-off. Part of the US regime is the FCC's obligation to reassign analog frequencies after the switch-off has taken place by means of auction. Spectrum auctions, however, originate not from the US but from New Zealand, where they have been used since the end of 1989 and ever since been subject to legal and political criticism. The article outlines the principles of both the DTV and spectrum auctions regulation and shows the links between both areas of telecommunications regulation. It concludes by suggesting that the analog switch-off is a unique opportunity to reconsider current spectrum policies, as it frees large amounts of the radio spectrum that are today occupied by analog broadcasting and will soon be subject to one of the biggest frequency reassignment processes in the history of telecommunications regulation.  相似文献

This paper investigates whether a disaggregated measure, labor productivity in manufacturing, is converging across eight OECD countries during the period 1950–1998 using both cross-section and time series tests of convergence. The evidence indicates convergence using either test for the full sample, but tests over subperiods suggest that the dynamics of the underlying series change from economies in transition in the early years to economies in balanced, but parallel, growth paths in the later period. The results confirm that the appropriate test for convergence depends on the underlying structure of the data.  相似文献

Convergence between technologies can be regarded as an increasingly emerging trend, and has received particular attention in the coming-together of previously distinct products and solutions within the information and communication technologies (ICT) industry. In previous research, the overall impact of the convergence phenomenon remains ambiguous. Whereas some scholars suggest convergence to be associated with disintegration, entry and growth, others relate the phenomenon to opposite effects, such as consolidation and shakeouts. This inconsistency in managerial conceptions on convergence formulates a need for an integrated understanding. Within a multi-case study approach, the convergence within ICT has been observed through examining the coevolution of actors in a converging environment, and patterns in innovation dynamics and managerial responses have been identified. In reflection with existing models of innovation cycles, a model for convergence innovation processes is elaborated and discussed. In particular, the reasoning within the ICT case set is transferred onto the currently emerging entrepreneurial activities in the intersection between nano- and bio-technologies (NBT), resulting in a comparison between ICT and NBT convergences, and deriving recommendations from a retrospective to a predictive context.  相似文献

中国地区收入差距、全要素生产率及其收敛分析   总被引:133,自引:9,他引:124  
彭国华 《经济研究》2005,40(9):19-29
本文在测算和分析1982—2002年省区全要素生产率(TFP)的基础上进行TFP的收敛检验,并与收入(劳均GDP)的收敛模式做了对比分析。分析表明TFP解释了我国省区收入差距的主要部分;我们应用OLS、PanelData固定效应估计方法和DynamicPanelData(一阶差分GMM)方法进行收敛检验,得出的结论是:TFP与收入的收敛模式具有很大的相似性,全国范围内没有绝对收敛,只有条件收敛,但是TFP的收敛速度明显高于收入的收敛速度。三大地区中只有东部地区存在俱乐部收敛现象。而且,我国TFP与收入的收敛模式与世界范围的TFP和收入的收敛模式具有很大的相似性。  相似文献
