City Innovation Ability In Yangtze River Delta Interregional Spillover Effect Research

Improving the ability of independent innovation will be as the core to enhance the country’s competitiveness during the" 12TH FIVE-YEAR PLAN".Some issues become the hot topics in the study of experts and scholars from all walks of life wide public concern like How to improve the ability of regional independent innovation and how to establish regional innovation system and how to reduce the problem of the difference of regional innovation ability. With the deepening of the research, innovation agglomeration phenomenon becomes more and more sure for academia, some research suggests that innovation cluster related to the spillover effect. The initial study of innovation spillovers limited within the region, with the rapid development of spatial econometric tools, academia began to focus on innovation between the interregional spillover, think the interregional spillover effect between innovation affect innovation geographic space agglomeration, but the interregional spillover effect is the direction of the innovation by the innovation of the interregional spillover effects and the interregional by overflow effects.Overflow of new economic geography theory and the theory of knowledge, drawing on regional economic growth theory Interregional overflow spillover effects to decompose, respectively Interregional Research and Regional spillover effects mechanism by overflow effector mechanisms, and through space measurement methods and classical measurement methods be modeled, Yangtze River Delta cities of our country for the study, empirical analysis from the two dimensions of time and space. The main research content of this paper is divided into four parts:The first part of the study of the mechanism of inter-region by the overflow effect, inter-regional and inter-regional spillover effects integrated overflow. Regional spillover effect refers to a regional technical trade, technical cooperation and other activities through all areas adjacent thereto, so that all elements of the spread of innovation from the region to the adjoining region, resulting in adjacent areas of knowledge acquired, personnel quality, innovation, and technology aspect is improved, thereby stimulating the adjacent areas to improve innovation capability. Interregional overflow effect refers to an area that is due to its own knowledge acquisition, knowledge creation, social and economic development, regional innovation environment and other factors to attract innovative elements adjacent areas of transport in the region, leading to innovation capacity in the region to further improve. Regional Integrated Regional spillover effect is the spillover effect and interregional consolidated results by overflow effect, reflecting the impact of innovative interactive regions on regional innovation capability.The second part of the exploratory spatial data analysis methods of urban innovation capacity in space to study distribution of Yangtze River. In the city of patent applications as innovation capacity index, the global spatial autocorrelation analysis showed that:the Yangtze River Delta city of innovation spatial autocorrelation gradually increased, there is a spatial concentration of innovation. To further analyze the characteristics of innovation cluster, using local spatial autocorrelation analysis methods found:Jiangsu province city of innovation capability gap gradually reduced, within the city of Zhejiang Province increased innovation capability gap, Shanghai and its surrounding cities to form a high innovation capability high gathering circle, tucking outer layer is formed in the high low high agglomeration belt, Xuzhou, Lianyungang and Suqian form whispered parks. From the temporal evolution of point of view, the city has a serious innovation path dependence.The third part of the interregional spillover effect and interregional relations by overflow effect and Innovation Agglomeration phenomena. Were established by the Interregional by overflow effects model and inter-regional spillover effects model, using classical measurement methods, patent applications and select cities in Yangtze River Delta region as a regional innovation capacity variable D personnel and funding as an innovative and creative human capital input variables, Geospatial city as a geographical distance between the weight index, on the occasion of the Yangtze River Delta city district and inter-regional spillover effects overflow effect by regression analysis. The results showed that:international spillover effects and Shanghai (1) Jiangsu Province as a whole is high, belongs to the Regional spillover effects leading provinces (municipalities), and Zhejiang overflow effect by strong inter-regional, inter-regional subject to overflow effect belong to the dominant province; (2) to gather in Shanghai as the center circle high to inter-regional spillover effects as conduction, forming a good collaborative innovation environment; (3) Xuzhou, Lianyungang and Suqian whispered gathering area formed by the surrounding area and its own innovation capacity constraints, interregional spillover effect and the effect is not obvious by the overflow effect, enhance regional innovation capability hindered; Low High agglomeration belt (4) and Jiaxing, Huzhou City, and other places of formation, low absorptive capacity for innovation, interregional spillover and by the overflow effects on regional innovation capacity increased limited role; (5) Regional spillover effects and ability to innovate by overflow effect on the regional effects of regional innovation capability itself and surrounding areas affected by the impact of innovation and strong regional, inter-regional spillover effects and by the effect of strong overflow effect; (6) compared to the Interregional overflow effect by the ability to innovate, the region affected by the spillover effects of the peripheral area of innovation greater impact.The fourth main urban innovation capability Interregional Comprehensive spillover effects Yangtze River Delta region. Through the establishment of inter-regional integrated overflow model using spatial econometric method selected cities patent applications as a regional innovation capability variables, Research and Development personnel and funding as an innovative human capital investment and innovation, on the occasion of the Yangtze River Delta area of the spillover effects of urban spatial lag regression and Geographically Weighted Regression Model Regression. The results showed that:(1) regional innovation capital investment has a positive impact on regional innovation capability, described regional innovation capital investment approach is to enhance regional innovation capability; (2) regional innovation staff input on Regional innovation is not significant, and the Yangtze River Delta Regional innovators not high on R & D capability; diffusion effect (3) innovation leading to the city in Jiangsu province decreased for innovation capability gap, innovation is the result of the combined effect of the inner city, Zhejiang Province, to increase innovation capability gaps reasons.Through the study of the above-mentioned four areas of focus topics, the paper concludes with three proposals, one to increase investment in education and training of qualified R & D personnel; the second is to strengthen the research collaborative innovation, improve innovation performance; Third, make full use of the advantages of geographic proximity Enhanced cooperation and exchanges between regions; innovation and development policies should be developed four of the city and be focused on innovation and development stage according to their geographical.
