在新一轮科技革命浪潮中,制造企业基于智能制造带来的颠覆性创新效应,既能把握市场先机,也易于实现“创新逆袭”。智能制造如何赋能企业颠覆性创新?围绕这一问题,以海尔集团深度访谈质性数据为基础,采用扎根理论对一手数据与二手数据进行编码,结果发现,生产模式变革、组织结构演化、合作网络创新是颠覆性创新的重要影响因素。由此,构建智能制造企业颠覆性创新理论模型,解析智能制造企业颠覆性创新实现与演化机理,以期为新时代背景下,中国企业更好地激发自身智能制造潜能,推动颠覆性创新提供参考。  相似文献

本文利用中国31个省区169个制造业在1999~2009年的数据,实证分析了专业化、多样化和竞争程度等因素对制造业增长的影响。研究结果表明,在全国样本范围内,专业化(MAR外部性)对制造业增长的影响为负,而多样化的产业环境(Jacobs外部性)和竞争(Porter外部性)有利于制造业的增长。在分地区、分产业和分地区分产业的分析中,专业化和多样化对不同地区和不同类型的制造业增长的影响存在显著差异,但是竞争对制造业的增长始终具有显著正面效应。  相似文献

Efficient development of industries requires a broad range of technological capabilities which can be acquired only by a long process of learning. Continuous measuring and monitoring of the ever-changing technological learning would be useful for building technological capability and managing technological policies. Nevertheless, research on how to measure the technological learning over time at macro levels remains largely untouched. In this paper, by adding the experience curve into the multifactor productivity part of Neoclassical production function, we will develop a model which will allow one to estimate the technological learning levels over long periods. This model would allow a user to both estimate the past learning experiences and forecast its future path on a time varying basis. The model has been used and tested in the estimation of the annual technological learning values for 28 Turkish manufacturing industries from 1981 to 2000.  相似文献

Build-to-order (BTO) and lean manufacturing processes are changing the paradigms under which businesses-to-business marketers operate. For example, BTO processes allow marketers to customize products to a greater degree, creating a competitive advantage over traditional manufacturing. Business-to-business (B2B) marketers who take advantage of the operational efficiencies and effectiveness that emerge from BTO are outperforming firms that utilize traditional manufacturing processes in multiple industries, such as office furniture, personal computers, and windows. This paper examines the long-term impact of the adoption of build-to-order manufacturing strategies on the marketing function and identifies marketing strategies associated with successful BTO companies. Throughout, the paper highlights managerial implications and proposes directions for future research.  相似文献

Manufacturing output per head rose at an unprecedented rate in the UK in 1981/2, and conventional econometric relationships failed to forecast the associated falls in employment. In this paper we estimate manufacturing employment equations in which output expectations play a central role. These compare fabourably with alternative models, and are able to predict most of the large falls in employment over this period.  相似文献

The entry of new firms into markets plays an important role in efficient resource allocation and evolution for long term economic growth. Employing dynamic panel data techniques, this paper investigates entry behavior in 66 four-digit Turkish manufacturing industries for the 1993–1999 period. The results of this paper suggest that potential entrants observe the market before the entry takes place; entry is, in general, a follow-up process; and incumbent firms seem to collude to prevent entry in Turkish manufacturing industries. In addition, the real interest rate appears to be a very important determinant of entry decision.  相似文献

Does social capital determine innovation? To what extent?   总被引:1,自引:0,他引:1  
This paper deals with two questions: Does social capital determine innovation in manufacturing firms? If it is the case, to what extent? To deal with these questions, we review the literature on innovation in order to see how social capital came to be added to the other forms of capital as an explanatory variable of innovation. In doing so, we have been led to follow the dominating view of the literature on social capital and innovation which claims that social capital cannot be captured through a single indicator, but that it actually takes many different forms that must be accounted for. Therefore, to the traditional explanatory variables of innovation, we have added five forms of structural social capital (business network assets, information network assets, research network assets, participation assets, and relational assets) and one form of cognitive social capital (reciprocal trust). Based on the survey data administered from April to June 2000 to 440 manufacturing firms of diverse industries in a region in the southwest of Montréal, we have found that 68.5% of the firms have developed product or process innovations during the 3 years preceding the survey. Assuming that innovation is not a discrete event but a complex process, we have modeled the decision to innovate as a two-stage decision-making process: in the first stage, the firms deal with the decision about whether to innovate or not whereas, at the second stage, the firms that have decided to innovate must make a decision about the degree of radicalness of the innovation to undertake. In a context where empirical investigations regarding the relations between social capital and innovation are still scanty, this paper makes contributions to the advancement of knowledge in providing new evidence regarding the impact and the extent of social capital on innovation at the two decision-making stages considered in this study. Regarding the decision to innovate or not that firms must initially make, we have provided strong evidence that diverse forms of social capital influence this decision and, more importantly, that marginal increases in social capital, especially in social capital taking the forms of participation assets and relational assets, contribute more than any other explanatory variable to increase the likelihood of innovation of firms. As for the decision to be made at the second stage concerning the magnitude of radicalness to bring in the development of new product or process innovations, this paper contributes to the advancement of knowledge by supplying the strongest evidence that diverse forms of social capital determine the radicalness of innovation, and more importantly, that social capital taking the form of research network assets contributes more than any other explanatory variable to explain the radicalness of innovation. The second variable that exerts the strongest impact on the radicalness of innovation is the number of different advanced technologies employed by firms for production.  相似文献
