Abstract: This paper, based on high-tech industrial panel data of 11 provinces along Yangtze River Economic Zone during 2007 to 2016, establishes indexes marking technical innovation efficiency from perspective of input/output, and uses ultra-efficiency DEA model and panel threshold model to study the influence of governmental allowance and financing concentration on technical innovation efficiency. Research indicates the average technical innovation efficiency of high-tech industry is 1.193, with outstanding variance among the up-, middle- and down-stream, high in both up- and down-stream and low in middle-stream. There is an obvious three threshold effect between governmental allowance and technical innovation efficiency. Influence intensity and direction of governmental allowance on innovation efficiency vary with financing threshold ranges.

Key words: governmental allowance, financing concentration, technical innovation efficiency, high-tech industry, Yangtze River Economic Zone

摘要： 采用2007—2016年长江经济带11省市高技术产业的面板数据，从投入产出角度构建了技术创新效率测度指标。运用超效率DEA模型和面板门槛模型实证分析了政府补贴、金融集聚对技术创新效率的影响。研究结果显示：1)高技术产业技术创新效率平均值为1.193，上中下游差距显著，其中上、下游地区创新效率较高，中游效率低；2）政府补贴与技术创新效率存在明显的三门槛效应；3）在不同金融门槛区间，政府补贴对创新效率的影响大小和方向不同。
