This paper takes the listed companies of manufacturing industry above Designated Size as sample, using multiple regressionto examine the relationship between corporate financial slack and R ＆ D investment under dynamic environment, using the Malmquist index method based on DEA model to analyze the innovation efficiency of Chinese manufacturing industry during the period of 2009-2013. The results show that： Financial slack and R ＆ D investment intensity presents inverted ＂U＂ type relationship in？sample？companies, and the relationship is positively regulated by environmental dynamism; Financial slackpromotes R ＆ D investment but have lag effect.展开更多

The results gave an average urban REE of 0.6381, and an average pure technical efifciency （PTE） and scale efifciency （SE） of 0.6964 and 0.9225, respectively. The results support the existence of a U-shaped relationship between REE and income level, which means that an increase in urban GDP does not result in an equivalent increase in environmental efficiency. Economic growth affects REE in three ways： scale effects （population scale and urbanization rate）; composition effects; and spatial effects. Improvements in urban resource use and environmental efifciency depend upon both technological innovation and effective governance. Policies designed to achieve these improvements should therefore be implemented at al levels of government and local enterprise.展开更多
