Patent citation data are used in a growing body of economics and business research on technological diffusion. Until now, there exists little evidence on whether patent citations are a good measure of knowledge flows. Our paper assesses the legitimacy of using European patent citations as a measure of technology flows. It uses information from the Community Innovation Survey collected by the French Service des Statistiques Industrielles (SESSI), which contain firms’ responses to questions about their innovative activity. We show that patent citations are indeed related to firms’ statements about their acquisition and dispersion of new technology, but that the strength and statistical significance of this relationship varies across geographical regions and across channels of knowledge diffusion.  相似文献

This paper develops and empirically tests a model that examines the role of technology readiness (TR) in the business-to-business (B2B) context. The research investigates how retailers' TR, and its antecedents, impacts their evaluation of a credence based B2B service, namely web solution service providers (WSSPs). It responds to previous research calls by extending the TR construct from the business-to-consumer (B2C) perspective that is traditional in the extant literature into the B2B domain. The findings of a survey conducted with 133 firms in the retail industry are that TR is an important contributor to the eventual achievement of service quality and satisfaction. The contributions of this study are; first it develops and validates a measure of TR in a B2B context; second it investigates the antecedents of TR in this domain, demonstrating the impact of past inexperience, industry trust and switching costs on firms' level of technology readiness to adopt online operations; and third, it finds that service quality and satisfaction are outcomes of TR. The key management implication for WSSPs is the need to address the TR levels of existing and potential clients if they wish to deliver successful e-business solutions to them. Their clients' TR can be better managed by making the offering more easily understood, building relational rapport, reducing risk perceptions and adopting a client centric perspective throughout the process.  相似文献

Despite their increasing size and importance in the regional economy, urban-to-urban migrants in China have received little attention in the literature and are often grouped with rural-to-urban migrants. We attempt to fill this gap by quantifying the patterns and determinants of urban-to-urban migration in China. We first document the sharply diverging spatial distribution of urban migrants and the widening gap in regional ability to attract human capital. Using a skill-based directional migration model, we also find strong preference for destinations with high concentrations of human capital among urban migrants, particularly for provinces in eastern China.  相似文献

目前,Web2.0工具的使用已相当普遍,并逐步渗透到了市场营销竞争情报工作中,对营销员的竞争优势和工作绩效产生了很大影响。为了解Web2.0工具在市场营销竞争情报中的应用现状及存在的问题,本文以镇江地区的小微企业为主要对象,进行了实证调研和统计分析。研究显示,目前Web2.0工具在小微企业市场营销竞争情报中的使用认知并不高,且多数企业缺乏成熟的Web2.0平台,而各类Web2.0工具的应用价值开发不完全,致使Web2.0工具的应用障碍较大。针对上述问题,本文提出了相应的建议。  相似文献

We provide evidence on the fit of the hybrid New Keynesian Phillips curve for selected Euro zone countries, the US and the UK. Instead of imposing rational expectations and estimating the Phillips curve by the Generalized Method of Moments, we use direct measures of inflation expectations from the CESifo World Economic Survey. Our main findings are as follows: (i) The use of survey data gives empirical results, which are more reliable than those obtained from the GMM approach. (ii) The purely forward-looking Phillips curve can be rejected in favor of the hybrid New Keynesian Phillips curve. (iii) The estimated coefficients on past inflation are higher when using survey expectations than when using the rational expectations GMM approach. (iv) It remains unclear whether real unit labor costs or a measure of the output gap should be used as a proxy for real marginal costs. (v) Theory-based restrictions lead to an improvement of the empirical results.  相似文献

We explore the role of evolving beliefs regarding the structure of the macroeconomy in improving our understanding of the term structure of interest rates within the context of a simple macro-finance model. Using quarterly vintages of real-time data and survey forecasts for the United States over the past 40 years, we show that a recursively estimated VAR on real GDP growth, inflation and the nominal short-term interest rate generates predictions that are more consistent with survey forecasts than a benchmark fixed-coefficient counterpart. We then estimate a simple term structure model under the assumption that investor risk attitude is driven by near-term expectations of the three state variables. When we allow for evolving beliefs about the macroeconomy, the resulting term structure model provides a better fit to the cross section of yields than the benchmark model, especially at longer maturities, and exhibits better performance in out-of-sample predictions of future yield movements.  相似文献
