建立政府补贴影响下的3代绿色技术扩散模型,用Matlab(2010b)拟合出不同潜在市场中每代绿色技术扩散的模拟图。分析结果表明:新技术的扩散率高于旧技术,政府补贴提高了每代技术的扩散率与扩散速度,也有利于促进绿色技术的升级扩散;同时,政府补贴在一定程度上弥补了不同技术之间的互补性或者创新性的差距,但政府补贴的积极影响只在技术进入市场的前期阶段效果显著,之后影响逐渐减弱。最后,根据所探究出的结论,为绿色技术的供给企业提出若干建议,以促进每代绿色技术达到最佳的扩散率。 相似文献

随着世界各国对可持续发展的逐渐关注,更多的国家注重有关绿色技术的研发和使用。然而,在实践中完全由市场机制进行运作,实现绿色技术的有效扩散,效率较低;因此,在大部分时候,中国社会中往往是以政府出面的方式,来承担实现绿色技术扩散的工作,但是,政府的作用也很有限。在政府和市场以外,探讨了影响绿色技术扩散的社会资本因素,分析了社会资本促进绿色技术扩散的作用机制,从本质上说,"扩散就是一个社会化过程。" 相似文献

基于市场诱致作用的绿色技术扩散层面与动力渠道研究 总被引：1，自引：0，他引：1
指出了产品供应链的系统传导作用为绿色技术在企业群落中的扩散提供了自然和充分的系统动力,绿色技术在物质流和信息流两个层面上的扩散是这种动力作用的具体反映。继而,运用演化博弈数学模型对绿色技术扩散的动力渠道问题进行了分析。研究认为,市场诱致作用下的"交易传染型"和"成功主体模仿型"是绿色技术在企业群落内得以高效扩散的两类最重要的动力渠道,反应了企业个体实施绿色技术变革的内在动机。在两类动力渠道的作用下,企业的清洁生产意愿得以强化,绿色技术转换环境得以改善。 相似文献

分析不同社会网络嵌入对农户绿色防控技术采用的影响及其作用机制,可为政府完善绿色农业技术推广政策提供决策参考。本文利用河南、陕西和甘肃790份苹果种植户微观调查数据,运用社会网络分析方法构建农户村域社会网络矩阵,基于关系嵌入和结构嵌入,探讨何种社会网络嵌入影响农户绿色防控技术采用及其作用机制。结果发现：①关系嵌入能显著提高农户采用绿色防控技术的可能性,结构嵌入的影响效应不显著。在控制其他因素的情况下,农户关系嵌入每增加一个单位,采用绿色防控技术的概率将提高13.5%~31.4%。②机制分析表明,关系嵌入通过增强农户技术认知广度和深度促进其采用绿色防控技术,结构嵌入对农户绿色防控技术采用的影响受到示范效应的调节,表现为结构嵌入仅对高示范效应组的农户绿色防控技术采用具有显著的正向影响,对低示范效应组的农户影响不显著。根据研究结论本文提出,政府应注重农户所嵌入的社会网络在绿色防控技术扩散中的媒介作用,加强农户互动水平,强化种植大户和家庭农场主的示范带动作用,加快实现农业绿色转型。 相似文献

Our objective in this paper is to analyse the determinants of the use of advanced manufacturing technologies in manufacturing firms. We go beyond more traditional approaches and consider the role of complementarities in technology adoption at two levels. First, we adapt Teece's (1986) framework to study the incentives to use new technology that stem from investments in R&D, human capital and advertising. Second, we analyse whether technology use is conditioned by a system effect that arises from the use of related technologies. We test our hypotheses on a representative sample of manufacturing firms in Spain. Our results fully support the idea that R&D investments increase the likelihood of technology use, but only offer partial support for human capital and advertising investments. Export intensity, being part of a business group and epidemic effects are also important determinants of adoption. 相似文献

技术融合是指原本相互独立的技术跨越其边界相互交叉渗透从而催生出新兴技术的现象，作为产业变革的核心动力其被认为是促进新兴产业形成及新产品开发的重要因素。本研究通过收集中国新能源汽车产业所有企业在2005至2017关于新产品的面板数据，通过专利IPC号的耦合结构与替代关系分别对互补性和替代性技术融合进行测度，并采用负二项固定效应回归模型，实证分析了跨领域技术融合与企业新产品开发绩效之间的关系。研究结果表明：当企业聚焦于特定领域采取替代性技术融合时，替代性技术融合强度越大越有利于提升企业新产品数量及新产品进入市场的速度；而当企业跨越多个领域采取互补性技术融合时，一开始有利于提升企业新产品数量及新产品进入市场的速度，但后期将不利于企业新产品数量与新产品进入市场速度的进一步提升。 相似文献

Recent literature has begun to discuss complementarities between sectors and technologies in the context of sustainability transitions. This paper contributes to this literature by theorizing complementarity formation mechanisms underlying such positive interactions within and across technology value chains. It pursues empirically founded theory building based on a case study of innovation in battery-electric, hydrogen and liquefied biogas technologies in Norwegian coastal shipping. Three complementarity formation mechanisms in technology value chains are identified: synchronization, amplification, and integration. Synchronization points to the need for co-development between the input and user sectors of a technology value chain. Amplification refers to the necessary expansion of input sectors to match the growing demand in user sectors. Finally, integration highlights the potential of convergence between different technology value chains in one or more user sectors. The paper concludes with a discussion of how policy may leverage such complementarity formation mechanisms to foster innovation in zero?carbon technologies. 相似文献

This paper reviews two recent research studies on Portuguese New Technology Based Firms (NTBFs). Attention is given to the role and contribution of NTBFs to innovation. The main argument is that, by and large, NTBFs are less concerned with the introduction of major innovations and more with creative adaptive improvements to products and services based upon new technologies first introduced elsewhere. The empirical research found that Portuguese NTBFs are a recent phenomenon associated with diffusion of Electronics and Information Technologies (EIT) during the late 1980s. They perform a wide variety of knowledge-intensive activities, which enhance local users' adoption processes and they are associated with different forms of technology transfer through external linkages. Overall, NTBFs undertake a frequently unobserved role as technology searchers and acquirers that, pushed by idiosyncratic local niche market opportunities, selectively choose among and enhance technologies developed elsewhere, introducing them into the local market. 相似文献

Most studies on knowledge diffusion and productivity focus on either R&D, foreign direct investment or patent citation flows, and rarely consider complementary, intangible investments such as business process redesign, the co-invention of new products and business models, and investments in human capital. Although the effects of complementary investments and their spillovers are often mentioned in the literature, there is a lack of in-depth research. This study aims to fill this gap, taking into account knowledge diffusion and complementarities between different intangible assets, and evaluating their effects on productivity. We propose new measures of knowledge, which consider these complementarities, by using principal component analysis (PCA) to aggregate intangibles, and the Niche overlap index to ease interpretation. The analysis is conducted on an unbalanced country-industry panel dataset of 13 European countries, constructed from a combination of sources such as INTAN-Invest, WIOD, World Bank and EU-KLEMS. We develop total factor productivity proxies, and estimate the effects of knowledge diffusion on productivity by means of GMM panel regressions. Results confirm the importance of considering complementarities for detecting knowledge spillover effects, especially in the case of domestic spillovers, while foreign spillovers are shown to be less effective, supporting the view of knowledge spillovers as a prevalently localised phenomenon. 相似文献

This paper augments the technological innovation systems (TIS) framework to provide policy guidance on how to manage interactions between a core technology and its larger sectoral context. A TIS development cycle is presented that combines the TIS framework’s ability to clearly illuminate policy gaps with Erik Dahmén’s idea that technological diffusion creates structural tensions that introduce transformation pressure. This pressure can result in stagnation and unrealized development potential or spur sectoral complementarities and the evolution of a TIS into a larger “development block” of interlinked technological systems. Integrating structural tensions into TIS analysis highlights how the evolution of a focal technology induces technological complementarities and creates a need to continuously re-design policies. This underscores the continued benefit of a technology system perspective, even as a technology matures.The revised TIS framework is applied to a case study of the Canadian province of Nova Scotia that explores how variable renewable electricity diffusion introduces structural tensions with existing electricity grids, requiring the use of complementary technologies that add storage and flexibility. Nova Scotia aggressively developed wind energy and built a high-voltage direct-current transmission line to import hydroelectricity that could back-up variable renewable energy sources like wind. 相似文献

Can the concept of speciation explain evidence on how technologies branch and advance? Can evidence on innovation through spin-off usefully inform the concept of speciation? These questions are addressed through a case study of detailed processes enabling the shift of technology to new domains of application. An innovative IT firm developed its own semiconductor technology to remedy supplier deficiencies but it required a joint venture with a completely new business model to adapt and move the technology into new market domains. We propose the concept of techno-organizational speciation to delineate this phenomenon. Competing perspectives on speciation (compatibility, niche and lineage approaches) are found to illuminate the evidence, while complementarities between these conceptual dimensions are revealed by the case. Causal processes uncovered include the following: (1) Techno-organizational speciation through spin-off may be needed to launch a dominant technical standard, compatible with multiple applications. (2) This can be achieved through niche creation from which develops a new business ecosystem. (3) Inherited knowledge together with organizationally based learning foster the branching and renewal of technological lineages. 相似文献

过去的几十年,中国通过支持偏离自身比较优势产业的发展使本国出口技术复杂度得到了快速提升,但这种发展同时伴随着政府的市场干预和较低的资源利用效率。我们以政府干预为切入点,利用STIRPAT模型并结合GMM-System估计方法研究发现：在排除市场扭曲干扰时,出口技术“适应性”偏离比较优势的赶超有助于提高资源利用效率,从而降低碳排放强度;考虑市场扭曲时,出口技术赶超的减排效应发生重要改变,具体地,市场扭曲使得出口技术较低程度的赶超不利于经济发展水平落后和资源要素富集地区的减排,只有当这种赶超在较大距离上偏离比较优势时则会扭转消极影响,但目前并未实现;市场扭曲抑制了经济发展水平较高和资源匮乏地区的资源、劳动密集型行业出口技术赶超对资源利用效率的积极效应。 相似文献
