中文摘要：

新兴市场企业试图通过逐渐加大自主研发以提升市场收益的竞争力，实现快速追赶，而此背景下研发强度是如何影响企业绩效至今并没有被充分揭示。本研究基于中国领先电子制造企业非平衡面板数据，在考虑IT投资强度和出口强度两个因素条件下，深入研究分析研发强度对企业绩效的影响模式。为了获得稳健的统计结果，本研究引入pooled-OLS和pooled-quantile两类回归检验技术进行对比分析。pooled-OLs回归展示了样本平均绩效水平上研发强度的影响，pooled-quantile回归描述了样本不同绩效水平上研发强度的影响。pooled-OLS回归结果表明，对中国电子制造业来讲，研发强度对企业绩效表现出稳健的显著正向促进作用；pooled-quantile回归更细致地揭示了研发强度对企业绩效作用的模式，表明研发强度对绩效越好的企业促进作用越强。

英文摘要：

Firms in emerging market try to increasingly investment in the indigenous research and development （R＆D） for improving the competitiveness of market profits, and realize quick catch-up. However, how R＆D intensity influences on firm performance has not been explicitly untangled in this context. We have explored the relationship between R＆D intensity and firm performance in the consideration of the participations and moderations of information technology （IT） investment intensity and export intensity using a unique unbalanced panel data set for the top China＇s electronic manufacturing firms during 2003-2007. In order to strengthen the statistical results, this study includes two major models to compare： pooled-OLS regression and pooled-quantile regression techniques. A series of pooled-OLS-based examinations focused on mean effects produce the robust evidence of a positive relationship between R＆D intensity and firm performance in the China＇s electronic manufacturing firms. By pooled-quantile regression techniques portraying the relative importance of explanatory variables at different points of the performance distribution, we have shed light to the underlying in-depth relationship between R＆D intensity and firm performance. We found that the R＆D intensity shows the stronger impact on the better-performance firms.
