后金融危机时代中国建筑业创新驱动发展绩效研究

Research on innovation-driven development performance in Chinese construction industry during post-financial crisis era

为探索后金融危机时代中国建筑业创新驱动发展绩效的演变规律,鉴于创新驱动发展主要依靠全要素生产率(TFP)提升推动的客观事实,使用索洛余值法对2008—2016年建筑业全要素生产率变化(SR)及科技进步贡献率(SRR)进行了测算。结果表明整个研究期间SR及SRR依次呈现明显的下降(2008—2011)、上升(2012—2013/2012)、下降(2013—2015/2012—2015)、上升(2016)波动趋势。对演变的原因进行了讨论,认为第一个下降趋势主要是政府主导的输入型创新驱动增长造成的,而其余波动趋势主要是市场主导的内生型创新驱动增长造成的。从政策的视角上看,未来应减少政府行政干预,让市场在建筑业创新驱动发展中发挥决定性作用。

To explore the evolution of innovation-driven development performance during the post-financial crisis era,in view of the fact that innovation-driven development mainly depends on total factor productivity(TFP)growth,this paper employs Solow Residual method to measure TFP change(SR)and the contribution rate of science and technology(SRR)in Chinese construction industry from 2008 to 2016.The results indicate that during the surveyed period SR and SRR had an obvious fluctuating trend,namely falling,rising,falling and rising in turn.The causes of such evolution were discussed.It is believed that the first downward trend was driven largely by government-led input innovation-driven growth,while the rest was mainly driven by market-led endogenous innovation-driven growth.Judging from the perspective of policy,the interference from the government should be reduced.By doing so,the market will play a decisive role in the innovation-driven development of construction industry.
