[Abstract]:Technological innovation is an important indicator to measure the regional economic situation and regional competitive strength. To explore the technological innovation capability of provincial region, to clarify the internal driving force of the technological innovation of all provinces, economic circles and even the whole country, to investigate the effect of knowledge spillover on technological progress, and to analyze the coupling effect of regional technology and regional innovation in depth. It is of great significance to promote the coordinated and balanced development of regional industrial sectors, analyze the dynamic fluctuation of the subsystems of technological innovation, and look forward to the future development trend of technological innovation.
This paper puts forward a method of evaluating the technological innovation ability of provincial domain, which combines the wavelet analysis with the improved grey entropy TOPSIS method - WP method. First, the wavelet analysis, the improved grey entropy TOPSIS method and so on are explained in detail, and the advantages and disadvantages of all kinds of multi attribute comprehensive evaluation methods are summarized. Then, the technological innovation ability of the provincial region is studied. In the background, the meaning of technological innovation ability is analyzed, and the evaluation index system of provincial technological innovation ability is constructed. Then, the time series data of 31 provinces and cities in China from 1995 to 2011 are decomposed by wavelet analysis. According to the energy conservation law of wavelet analysis, the weight of energy and index weight after wavelet decomposition is selected to express each province. The fourth step is to analyze the technological innovation ability of 31 provinces and cities in China by entropy method, grey entropy TOPSIS method and WP method. Then, based on the above results, the influence factors are analyzed. Finally, the comprehensive competitiveness of the provincial economy is raised, the input and output of scientific and technological resources and the technological innovation environment are increased. The optimization point of view is to analyze how to enhance the technological innovation ability of the three economic zones (Beijing, Tianjin Tangshan, Yangtze River Delta and Pearl River Delta), and choose the economic radiation path centered on the economic agglomeration area.
The conclusion of this paper is that by examining the Spearman grade correlation of the comprehensive ranking of the empirical results and the regional innovation capability report, it shows that the WP method is obviously superior to the other methods in revealing the economic agglomeration of the provincial technological innovation and the accuracy of the provincial technological innovation capacity. The effective use of knowledge and technology spillover effect makes it easy to realize the rationalization of the resource endowment of technological innovation, coordinate and allocate the proportion of the industry, realize the high efficiency of the technological innovation, and provide the basis for the enhancement of the technological innovation ability of the province, the coordinated development of regional technological innovation ability and the construction of the national technological innovation network. Provide scientific and technological support for the sustained and steady development of the economy.
This paper selects the time series data of the technical innovation capability indexes of provinces and cities from 1995 to 2011, and changes the method of setting index from knowledge creation and acquisition ability in most of the papers, and constructs a dynamic comprehensive evaluation model of provincial technological innovation ability from the angle of input and output of scientific and technological resources, and evaluates the technological innovation ability of each province. The main innovations are as follows: firstly, the wavelet transform, which is used in image recognition and data compression, is used in the analysis of provincial technical innovation index data, to remove the heteroscedasticity and non-stationary in the economic signal, and to obtain the data of the most essential economic fluctuation after "denoising", and fully embody the advantages of the time frequency locality of the wavelet decomposition. According to the energy conservation theorem of wavelet decomposition, the technical innovation ability of various provinces and cities is characterized by the norm of each index energy. Second, the essential information reflected by each index is expressed by the index data of smoothing denoising by wavelet analysis, the time dimension is added to the Euclidean norm of each index to solve the process, and the improved grey entropy TOPSIS method is selected to carry out the index right. The weight setting overcame the shortcomings of the traditional index weight solving method, which made the weight calculation more scientific and perfect, and smoothed the weight of the data after the denoising and characterized the technological innovation ability of the provinces more accurately.
