Abstract: Under the background of the new normal of China’s economy, the innovation efficiency enhancement and quality improvement of enterprises in high-tech zones can prominently step up the innovation ability of high-tech zones. From the perspective of the innovation value chain, the innovation process of enterprise was classified as two stages, namely, technology development and economic transformation, in this article. More specifically, this article analyzed the overall innovation efficiency, technology development efficiency and economic transformation efficiency of twelve national high-tech zones, eleven technical fields and enterprises of different technical types in twelve national high-tech zones in Jiangsu Province in 2016, along with their influencing factors, by using two-stage DEA model and Tobit Regression model. The results show that: (1）national high-tech zones in Jiangsu Province still has great room for improvement in terms of the overall innovation efficiency, among which the technology development efficiency is slightly higher than the economic transformation efficiency. (2）The technical fields with high innovation efficiency mainly include electronic information, new materials, etc., while the overall innovation efficiency in the technical fields of biomedicine, environmental protection and opto-mechatronics are at a low level. (3）Four models of innovation resource utilization are classified based on boundary line with average efficiency of two stages. Most of enterprises are in high-development and low-transformation model, as well as low-development and high-transformation model, indicating the disconnection between technology innovation and economic transformation. (4）The influence of the level of capital input, high-quality labor force, workforce and government support on the innovation efficiency of enterprises is obviously different in different stages. Finally, according to the research results, the policy suggestions for improving innovation efficiency of enterprises in high-tech zones include strengthening the knowledge exchange network, retaining diversified talents, adjusting resource input and output evaluation methods and developing one’s strengths and making up one’s weaknesses.
