论文摘要
本文分析了公司在金融危机之前实施的创新活动及其绩效之间的联系。分析了有关意大利证券交易所星市场领域中列出的公司的相关数据。创新是通过2006- 2007年在有形和无形的固定资产中的投资水平来衡量的，而绩效是通过销售或总资产的变化来捕获的，即通过ROI或ROS ROSE的盈利能力 - 通过投资回报率或ROSE Evolution和生产力 - 通过资产交换或销售/销售/员工在2008-2010期间通过资产交换或销售/员工。通过统计技术和采用聚类分析来分析感兴趣的变量并进行比较。特别是，在不同的质心框架中实现了Voronoi Tessellation。按照文献的很大一部分，我们发现公司绩效的行为在创新时并不是一立上的。统计异常值是提出有效策略的最佳案例。简而言之，发现积极的投资率是可取的。
This paper analyzes the connection between innovation activities of companies -- implemented before a financial crisis -- and their performance -- measured after such a time of crisis. Pertinent data about companies listed in the STAR Market Segment of the Italian Stock Exchange is 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 or of total assets, -- profitability -- through ROI or ROS evolution, - and productivity -- through asset turnover or sales/employee in the period 2008-2010. The variables of interest are analyzed and compared through statistical techniques and by adopting a cluster analysis. In particular, a Voronoi tessellation is implemented in a varying centroids framework. In accord with a large part of the literature, we find that the behavior of the performance of the companies is not univocal when they innovate. The statistical outliers are the best cases in order to suggest efficient strategies. In brief, it is found that a positive rate of investments is preferable.
