Abstract

R＆D activity is the most important part of science and technology activities. Nowadays，in the rapid development of science and technology，the regional economy of one country is highly depended on the support of science and technology. At the same time，the development of science and technology has become the most important means of economic growth of one country. R＆D activities，the core of science and technology activities，are also endowed with new historical mission. The level of R＆D activities of a country determines the strength of the modern economic competitiveness.

In this situation，R＆D level of developed countries is higher than the developing countries. To build an innovative country is the guiding ideology in the present development stage of our country. It primarily requires the innovation in economic development. The innovation of economic development is to change the mode of economic development. R＆D is an important part of the transformation of the economic development mode，and it will play a more and more important role in the subsequent economic development. At the same time，R＆D is also in line with the development of economic globalization. Many countries in the world are actively moving closer to the new economic development approach. R＆D has become a key vehicle for global economic competition. In recent years，our country made a lot of effort on supporting the cause of science and technology，such as increasing R＆D input and paying continuing attention to the R＆D input performance. These kind of actions had a positive role in promoting technological competitiveness of our country. But due to the huge regional differences among the whole country，the regional R＆D activities have very distinct characteristics. At the same time，there are a lot of questions need to be settled such as the input of regional R$D is incomparable，the performance of R＆D input is low，etc. Therefore，the research on regional R＆D activities in China is very necessary. Strengthening regional R＆D investment performance evaluation helps to clarify the main directions of regional R＆D activities. Providing targeted countermeasures and suggestions for regional R＆D investment should be able to optimize the allocation of R＆D resources in the region and provide a good environment for the further development of R＆D activities. This kind of actions not only promotes regional R＆D development but also enhances China's international R＆D competitiveness and overall competitiveness in the long run.

This paper starts from the literature review of four parts，the connotation of R＆D input，the factors affecting R＆D input performance，the method and model of R＆D input performance evaluation and the strategy of improving R＆D input performance. And then discusses the interaction mechanism between R＆D input and R＆D innovation. The interaction mechanism of input and regional development is based on the theory of technology innovation，principal-agent theory，contingency theory，and stakeholder theories such as economics and management theories. The indicator system of regional R＆D investment performance evaluation is preliminarily constructed，and a correlation analysis is adopted. Other statistical analysis scientifically selected evaluation indicators and established a regional R＆D input performance evaluation indicator system composed of two first-level indicators，four secondary indicators，and fifteen third-level indicators. The status of input and output in regional R＆D and influencing factors Based on the analysis，Delphi method and AHP method，principal component analysis method，cluster analysis method and data envelopment analysis method were used to conduct empirical research on regional R＆D investment performance evaluation. Finally，SWOT analysis model was applied to the area. The empirical research results of R＆D input performance evaluation put forward targeted and operational strategic recommendations.

Through the empirical research of a variety of qualitative and quantitative methodsmentione，the final conclusions of regional R＆D investment performance evaluation in China have been reached：Jiangsu，Guangdong，Beijing，Zhejiang，Shandong，and Shanghai have performed best in the three methods used in this paper，these cities have high-performance on regional R＆D investment research. Liaoning，Henan，Shaanxi，Sichuan，Hunan，Hubei，Tianjin and other regions are in a rapid development stages in the R＆D investment performance，these cities are among the middle levels. Finally，there are a lot of improvement space for the rest of cities of our country. In general，the R＆D investment performance of the eastern coastal areas of China is significantly higher than the central and western regions.

The study considers that the R＆D investment performance varies greatly among regions in China. It divides China's R＆D investment regions into three categories，performance-leadingregions，performance-developing regions and performance-lagging regions. Performance-leading regions should adopt strategies such as optimizing R＆D，actively innovating independently，strengthening the cultivation of world-class experts，encouraging enterprise-led R＆D activities，cooperating between production and research，promoting intellectual property protection and creating international R＆D cooperation to increase regional R＆D investment performance and so on. Performance-developing regions should actively adopt high-end talent introduction and talent training at home and abroad，encourage independent innovation and support，improve incentives for fiscal and taxation policies，strengthen regional scientific research institution capacity building and implement R＆D results promotion and application strategies to increase regional R＆D investment performance and so on. Performance-lagging areas should focus on R＆D resources joint research，encourage diversified R＆D investment，actively cultivate leading industries，optimize R＆D input structure，pay attention to R＆D personnel education，strengthen scientific popularization，improve the general quality of workers，share R＆D basic conditions and persist in strategies such as poverty alleviation through science and technology to increase the level of regional R＆D investment performance.
