摘要: 生态优先、集约发展是推进长江经济带发展战略的核心。本文采用Super-Efficiency及Undisirable-SBM模型,对长江经济带11个省(市)2005-2016年绿色技术创新效率(Green Technology Innovation Efficiency, GTIE)分技术研发(E1)、技术交易(E2)、产品试验(E3)及产业化(E4)四阶段测算其动态变化趋势,并基于Durbin模型分析环境规制对E1和E4的GTIE影响。研究发现:(1)低技术效率导致长江经济带整体GTIE偏低且波动明显,效率呈下、中、上游递减的分布态势;(2)GTIE在产品试验、产业化、技术研发及技术交易环节上呈递减趋势,且在环节E1上增长最缓慢,区域分化格局现象最明显;(3)GTIE在技术研发阶段的溢出效应程度不如产业化阶段。命令型规制对绿色技术创新不同阶段的效率值影响均不显著,但市场型规制显著促进了产业化段的GTIE,公众型规制显著促进了技术研发段的GTIE。最后从发挥禀赋优势、全链突破及动态调整环境规制政策等角度提出建议。

Abstract:   Ecological priority and intensive development are the core of the national strategies for promoting the development of the Yangtze River economic belt Based on the super-efficiency model and the undesirable-SBM model, the green technology innovation efficiency (GTIE) is calculated respectively from four stages of technology development (E1), technology transaction (E2), product testing (E3) and industrialization (E4) in 11 provinces (cities) in the Yangtze River economic zone from 2005 to 2016 The dynamic change and the impacts of environmental regulations on E1 and E4 are analyzed with the spatial Durbin model The research indicates that: (1) Low technical efficiency brings low GTIE, and GTIE fluctuates obviously, showing a decreasing pattern in the lower, middle and upper reaches (2) The efficiency shows a decreasing trend in product testing, industrialization, technology development and technology transaction, and GTIE rises slowest and has the most obvious regional differentiation pattern in E1(3)The spatial spillover effects in technology development stage is inferior to those in industrialization stage The commanding regulations have no significant effect on GTIE in different stages However, the market regulations have a significant impact on GTIE in industrialization stage, while the public regulations have a significant impact on GTIE in  technology development stage At last, some suggestions are put forward from the perspectives of developing the advantages of endowment and dynamically adjusting environmental regulations

Key words: green technology innovation efficiency, innovation value chain, spatial spillover
