运用协整理论和Granger因果检验方法,分别对广东省1991-2007年间三大引文系统收录的文章篇数、专利申请量、技术市场成交额与经济增长之间的因果及定量关系进行研究,阐明了经济增长和科技创新及转化效率之间的作用关系.研究结果显示,广东省创新产出效率与经济增长的协整和单向因果关系并不成立,创新效率对经济增长的影响作用有限,产出效率对经济增长的推动作用不显著.创新转化效率与经济增长之间虽然不具备长期稳定的均衡关系,但却是经济增长的Granger成因,对经济增长具有显著的正向推动作用.依据对广东省有效数据的分析,探讨其现有科技发展模式的缺陷,对加快粤港澳三地的科技合作有重要的借鉴与启示作用. 相似文献

中国城镇居民旅游消费实证分析 总被引：1，自引：0，他引：1
对我国城镇居民旅游消费需求的研究有助于刺激居民消费,拉动内需,进而带动经济增长,、一般对居民旅游消费行为的数量分析,仅限于静态层次,不能反映变量间随时间变化的动态数量关系。本文建立了我国城46居民旅游消费与收入间的变参数模型,并利用EG两步法检验了变量间的变协整关系．以动态机制解读了我国城镇居民旅游消费状况,得出以下主要结论：1994—2006年我国城镇居民边际旅游消费倾向呈现先上升后下降的趋势,呈现一个动态变化的过程;城镇居民收入与旅游消费之间存在着均衡比例变化的变协整关系。 相似文献

研发产业与上海经济增长的协整与因果互动机制研究 总被引：2，自引：1，他引：1
以上海市经济增长为被解释变量,分别以被国外重要检索工具检索的论文数量、专利授权数量、技术市场成交金额及三者的合成指标为解释变量,基于协整和Granger因果检验模型,对上海市的研发产业与经济增长之间的协整与因果互动机制进行了实证研究。结果发现:虽然研发产业对上海经济增长有一定的贡献作用,但是受发展的机制、体制影响,研发产业与上海经济发展的良性互动机制还未建立,两者基本不构成Granger因果关系。 相似文献

文章基于向量自回归(VAR)模型,选取中国1999-2010年的季度时间序列数据,采用单位根、协整及Granger检验对中国股票市场发展和经济增长的相关关系进行实证研究.实证结果表明中国的经济增长与股票市场发展之间存在长期均衡关系;Granger因果关系检验进一步说明股票市场发展各指标变量之间不存在明显因果关系.因此,建议通过完善股票市场发展的相关机制,遏制过度投机行为与非理性市场操作,实现股票市场发展与经济增长的良性互动. 相似文献

用社会消费零售总额和GDP分别度量国内贸易和经济增长,并基于1980—2006年的统计数据,利用单位根检验、协整检验、因果检验及多元回归等计量研究方法,考察了国内贸易对经济增长的影响。经过研究,可以发现国内贸易与经济增长的关系并不是有些研究所得出的因果关系,而只是长期稳定的协整关系。同时在影响经济增长的众多变量中,消费的比重相对还是比较大的。这说明,在促进经济增长中,国内市场显得更为重要,尤其是消费市场。 相似文献

Cities and countries undergo constant structural transformation. Industries need many inputs, such as regulations, infrastructure or productive knowledge, which we call capabilities. And locations are successful in hosting industries insofar as the capabilities that they can provide. We propose a capabilities-based production model and an empirical strategy to measure the Sophistication of a product and the Production Ability of a location. We apply our framework to international trade data and employment data in the United States, recovering measures of Production Ability for countries and cities, and the Sophistication of products and industries. We show that both country- and city-level measures have a strong correlation with income and economic growth at different time horizons. Product Sophistication is positively correlated with indicators of human capital and wages. Our model-based estimations predict product appearances and disappearances through the extensive margin. 相似文献

This paper investigates the effect of being located in a cluster on firm growth. In particular, it focuses on the differential growth effect of being located in a cluster, or a growth divide among clustered firms, based on the idea that, contrary to the conventional wisdom, advantages of geographical clustering are not randomly or equally available to clustered firms. Due to the intense competition among clustered firms for resources such as creative talent, firms who are more attractive to the resources are more likely to entice better resources and hence achieve higher growth. Our empirical analysis of firms in nine industries across six countries shows that being located in a cluster per se does not have a positive effect on firm growth and that domestic technological leaders with a sufficient technological distance to the global technological frontier show differentially higher growth due both to the attractiveness to promising resources and to the opportunity for incoming knowledge spillovers from global technological leaders. 相似文献

Knowledge base combinations and firm growth 总被引：1，自引：0，他引：1
The link between knowledge and firm growth has been a core topic in economics of innovation for a long time. However, despite strong theoretical arguments, empirical evidence remains inconclusive. One important reason for this conundrum may be the failure of standard indicators to capture firm innovation activities comprehensively. We contribute to overcoming this limitation by looking in the knowledge processes that drive variegated forms of innovation and aim thereby to establish a solid relationship with firm growth in more detail. Our arguments draw on the differentiated knowledge base approach, distinguishing between analytical, synthetic, and symbolic knowledge. We measure the three types of knowledge bases with detailed longitudinal linked-employer-employee micro-data from Sweden. Econometric findings based on a very large sample of small and medium-sized firms indicate significantly positive effects of the three knowledge types, and in particular combinations thereof, on firm growth. In addition, we show that not only high-growth but also slow-growth firms benefit immensely from the use of combinatory knowledge bases. We find evidence on a curvilinear relation between knowledge bases and growth of firms. Beyond certain thresholds increasing the knowledge bases further results in decreasing firm growth. Our results remain robust in a wide range of specifications and econometric models. 相似文献

One the one hand, complex technologies offer substantial economic benefits, and on the other, they are difficult to invent and to imitate, and they refuse a fast dissemination. This two-sidedness motivates the idea that regions’ competitive advantages and, in consequence, their economic growth, originate in their ability to produce and utilize complex technologies. However, the relationship between technological complexity and regional economic growth has rarely been empirically investigated. Here, we address this pressing research gap by assessing the complexity of technological activities in 159 European NUTS 2 regions and relating it to their economic growth from 2000 to 2014. Our empirical results suggest that technological complexity is an important predictor of regional economic growth. A 10% increase in complexity is associated with a 0.45% GDP per capita growth. By showing that technological complexity is important for regional economic growth, our results fuel current policy debates about optimal regional policies such as the Smart Specialization strategy. 相似文献

This paper focuses on the dual role of R&D - knowledge generation and the technological-competence-enhancing effect of R&D - and its implication for the endogenous evolution of R&D productivity and the pattern of firm growth. In particular, based on the evolution of firm-specific R&D productivity or technological competence, this paper derives a simple R&D-based model of firm growth capable of explaining various aspects of firm growth. The model proposes three prototype patterns of firm growth, depending on both firm- and industry-specific characteristics. The former includes firm-specific technological-competence-enhancing capability and the initial level of technological knowledge, and the latter includes industry-specific R&D appropriability. Specifically, firms with low technological-competence-enhancing capability tend to follow a convergent growth pattern in which firm growth gradually declines, while firms with high technological-competence-enhancing capability tend to exhibit either a sustained or a vicious growth pattern depending on the initial size of their technological knowledge stock. An empirical analysis of unique data on firm growth and technological capability provides supportive evidence for the role of technological-competence-enhancing capability in conditioning the pattern of firm growth. 相似文献

随着经济增长方式的转变,绿色增长已经成为未来全球经济增长的主要模式。企业是一个国家或地区经济增长的主要载体,绿色增长的实施对于企业成长作用决定了经济增长的走势。因此识别绿色增长与企业成长之间的动态交互关系,可以为企业经济增长提供理论指导。本文选取1998-2012年间绿色增长与企业成长相关指标,建立绿色增长与企业成长的VAR模型,运用协整检验、脉冲响应函数、方差分解方法分析了绿色增长与企业成长的内在联系、互动机制与发展趋势。分析结果表明:绿色增长与企业成长在短期内处于波动状态,但存在着长期的均衡关系,即短期内绿色增长的实施会使企业成长减缓,但长期来看,企业成长将在绿色增长的作用下达到一个更高水平的发展阶段。同时,企业的成长也会促进绿色增长的有效实施,最后二者进入良性互动发展状态。 相似文献
