| As the new round of global technological revolution and industrial transformation are deeply promoting,the innovation has gradually been one of the core driving forces for the economic growth and a significant embodiment of competitiveness for a city,a region or even a country.In order to achieve high-quality economic development in the new era,China must stick to taking innovation as the main driving force.In recent years,China’s R&D expenditure has kept growing at a top rate.However,compared with the technological power such as United States and Japan,China’s innovation level is still lower with the obvious regional differences.In view of this,the research focuses on the different spatial scales,namely,the national,Eastern,Middle and Western regions as well as eight big economic comprehensive regions.Firstly,the innovation efficiency is statically evaluated by the DEA and dynamically evaluated by introducing Malmquist index.Secondly,the spatial-temporal evolution pattern of innovation efficiency difference is analysed in combination with variance coefficient and ArcGIS spatial analysis.Furthermore,Tobit model is used to identify the influence of the governmental factors and marketing factors on the overall efficiency of various spatial-scale innovations.Finally,the conclusion of this study is drawn and the targeted political suggestions are proposed.From the research,it’s found:(1)There are still some gaps between the regional innovation efficiency and that of the developed countries from 2004 to 2018,but the efficiency fluctuates.(2)The innovation efficiency of the nation,the eastern,the central and the western region,and eight major comprehensive economic zones is summarized.It is found that there is a general regional difference,namely,the eastern and the western is high.The central is low with a u-shaped feature,it has the feature of the high south and the low north.The prominence of the east-west problem is gradually switching to that of the south-north problem.(3)The improvement of national innovation efficiency is attributed to the common drive of both technical efficiency and technological progress.The improvement of innovation efficiency in the eastern and coastal regions mainly relies on technological progress,while the inland region like the central and western mainly relies on improvement of technological efficiency.(4)The improvement of national innovation efficiency is promoted by the government.Finally,some countermeasures are proposed such as enhancing the R&D investment,promoting market-oriented process,giving full play to regional advantages,strengthening the construction of innovation platform,encouraging the cultivation of innovation subject,and breaking the barriers against the system and mechanism in order to improve the efficiency of various regional innovation in this research. |
