本文首先从理论上分析了知识产权保护通过进口贸易影响企业创新的作用机制,随后,利用中国海关贸易数据与中国工业企业数据,实证分析了知识产权保护对企业创新的影响,并检验了知识产权保护通过进口贸易影响企业创新的作用机制。研究结果表明:(1)知识产权保护水平提高,能够显著促进创新型领军企业的创新。(2)从影响机制来看,知识产权保护水平提高,能够显著提升民营企业、专利密集型行业企业以及出口企业的进口规模,进而促进创新;能够显著提升民营企业和专利密集型行业企业的进口产品种类,进而促进创新;能够显著提升出口企业的进口产品质量,进而促进创新。中国正处在实施创新驱动发展战略的重要阶段,应重视并充分发挥知识产权保护与进口贸易对我国企业创新的促进作用。 相似文献

主流经济学家把改革开放后民营企业的大规模兴起,主要归因为市场经济条件下发挥企业家精神和遵循比较优势的必然结果。但是这无法解释为什么民营企业在兴起之初就广泛和快速地进入到各个工业,尤其是技术和资本密集型工业。基于中国工业史和252家中国最大民营制造业企业创业发展史的历史证据,文章找回"工业体系"这一被主流所忽略的重大历史现象和学术概念,从而首次提出一种理解中国民营企业发展独特性的结构性解释。文章发现:从计划经济时期继承而来的门类齐全和独立完整的工业体系,是解释民营企业创业和发展独特性的关键变量;已有的由国有企业和科研院所组成的工业体系,从市场机会、技术能力和组织资源等方面塑造了民营企业的创业选择和发展路径。所以,中国民营企业的快速发展不是仅凭自由市场就会自动出现的普遍现象,而是在市场条件下充分利用工业体系提供的技术和市场条件才得以出现的特殊现象。 相似文献

In combinatorial models of innovations, new technologies are built from combinations of pre-existing technological components. Researchers learn which components work well together by observing previously successful combinations and the pool of ideas can be ‘fished out’, i.e. exhausted, if it is not ‘restocked’ by the discovery of novel connections. We first show US patents have made increasingly less novel connections among technological constituents since the 1950s, and that the number of technological fields to which these connections are applicable has stopped growing since the 1980s. We then estimate the parameters of an ideas production function, and find parameter estimates consistent with technology fields being fished out if not continually restocked by the discovery of novel connections between technological components. We use the ideas production function to estimate the number of new patent applications induced by each patent granted between 1926 and 2001, and show this number has trended downward since the 1940s. 相似文献

This paper analyzes the connection between innovation activities of companies – implemented before crisis – and their performance – measured at time of crisis. The companies listed in the STAR Market Segment of the Italian Stock Exchange are analyzed. Innovation is measured through the level of investments in total tangible and intangible fixed assets in 2006–2007, while performance is captured through growth – expressed by variations of sales, total assets and employees – profitability – through ROI or ROS – and productivity – through asset turnover or sales per employee in the period 2008–2010. The variables of interest are analyzed and compared through statistical techniques and by adopting cluster analysis. In particular, a Voronoi tessellation is also implemented in a varying centroids framework. In accord with a large part of the literature, we find that the behaviour of the performance of the companies is not univocal when they innovate. 相似文献

This research looks into the innovative activities of subunits of large non-U.S firms in the U.S from 1969 to 1995, suggesting that the innovations in the subunits of multinational corporations are closely linked to their specializations in General Purpose Technologies (GPTs). GPTs enable recombining knowledge from different domains on an international scale, and that the specialization of innovations in GPT fields within a subunit is positively associated with the innovative capacity at large, along with the degree of technological diversification of that specific subunit. As firms expand geographically to tap into local innovation centers to develop new growth alternatives, specialization of GPTs in these firms actually facilitates further geographical dispersion of innovative activities across locations. Lastly, additional specializations of innovations in GPT fields within the host innovation centers does help in attracting innovation activities of firms from a wider range of industries. 相似文献

This study examines the effect of accounting restatements on corporate innovation strategy. Using a sample of restating firms and propensity-score-matched non-restating firms from 2000 to 2009, we find that, after restatements, restating firms experience a greater increase in exploratory innovation and a greater reduction in exploitative innovation compared to non-restating firms. These results suggest that restating firms are associated with an increased risk appetite as managers believe the upside potential may yield corporate improvement. The results also differ between fraudulent and non-fraudulent restatements, and among restatements of varying severity. The results of this study shed light on a previously unexplored consequence of accounting restatement and highlight its real impact on corporate business strategy. 相似文献

Using daily panel data from Detroit, we empirically explore the relationship between the National Football League (NFL) and crime in a city. We exploit the natural experiment of the Detroit Lions’ move from Pontiac, Michigan, to downtown Detroit in 2002. Pontiac is used as the treatment city and non-game day crime, other suburban cities, and other cities outside Detroit MSA are used as the comparison groups. Employing a difference-in-difference approach, we find decreases in assaults and vandalism on home game days in Pontiac relative to the control cities after the Lions’ move. We find weak evidence of a net decrease in larceny and vandalism in Pontiac on home game days following the loss of professional football. No changes in assaults and auto theft are reported. While not conclusive, our results suggest that professional football leads to additional larceny and vandalism incidents but no effects on assaults and auto theft. 相似文献
