Research On Structure And Evolution Of Agricultural Science And Technology Knowledge Network

In building an innovative country has achieved remarkable results,"Made in China " moment oftruth to the "China Zhi-made" to accelerate the transformation of the party’s " eighteen " Report on theimplementation of innovation-driven development strategy has made important deployment, technologicalinnovation put in the overall development of the country ’s core position. January19,2014, the CPCCentral Committee Document No.11consecutive years has been focused rural issues, Paper No.11specifically addressed the issue of agricultural science and technology innovation, clearly deepenagricultural science and technology system, and a series of important achievements tasks. As a largeagricultural country,"three rural" issue has been a fundamental problem of China’s economic growth. Thearrival of the knowledge economy and network society in the21st century, making the departure ofsocio-economic research organization and spatial development patterns become a trend in academicresearch from a network perspective. Analysis of the spatial and institutional levels structure and evolutionof agricultural technology knowledge network characteristics, dynamic mechanism for the development ofagricultural science and understand the status of the country, the flow and dissemination of agriculturalknowledge is important, help to promote agricultural science and technology innovation, accelerate thetransformation and application of agricultural scientific and technological achievements, and promote thedevelopment of modern agriculture, increasing farmers’ income and rural prosperity.On the basis of combing the literature on domestic and international knowledge network,combined with the development of agricultural science and technology background, empiricalresearch-based, full-text database using Chinese patent published in the field of agricultural science andtechnology cooperation patent for the study, to the authors attribute units and spatial properties of the datasource, with ucinet, Arcgis, CAD and Photoshop software, standing on a macro point of view, from thespatial and institutional levels, the first of the status quo of China’s agricultural science and knowledgenetworks in2012were analyzed in stages after analyzing the2000-2012cyberspace structure andevolution of the knowledge of agricultural science and technology, knowledge network analysis to explorethe dynamic mechanism of evolution, come to some conclusions about:China’s agricultural science and technology published patent growing, high technology content patents, the level of development of agricultural science and technology continues to increase. Formation ofChina’s agricultural science and technology knowledge network topology, showing the development andevolution of the initially formed, after the initial development phase of the transition to the rapidlyexpanding trend; China’s agricultural science and technology is a knowledge network expanded rapidlyemerging core nodes, isolated points and edge points gradually reduced, contact the core node and itssurroundings, the core point and edge nodes increasingly close network, increasing knowledge of thechannel, and hinder the diffusion of knowledge dissemination slowly decrease gradually increase thetightness of the network; topology transition from one pole to a few core, and then a very multicoreparadigm shift.In the space level, China’s agricultural science and technology cooperation in the form of thePatent Cooperation based in the province, fewer exchanges and cooperation between the province. Provinceshowed significant level of cooperation. Exchanges and cooperation between the provincial agriculturaltechnology patent is still relatively weak, in space also showed uneven state, large regional differences: theexchange of knowledge-intensive areas exhibit and then dispersed by a decentralized to a centralizedprocess, Beijing, Yangtze River Delta, Guangdong and southwestern Yunnan, Sichuan and intensiveagricultural areas become China exchanges and cooperation in scientific and technological knowledge,western and northern provinces have steadily involved, the national agricultural technology and rapidlyevolving knowledge network expansion; knowledge diffusion by contact diffusion of main changes to levelthe diffusion-based. Consistent spatial structure and evolution of the network of agricultural technology andknowledge, spatial pattern and development trend of China’s economic and social development ofagriculture. Of individuals, organizations or groups active participation, integration of knowledge exchangeand cooperation in agricultural science and technology awareness is still relatively low.At the institutional level, the same unit of the author and co-authored the patent is the subject ofthe patent, less cooperation between different units of the author. Enterprise has always been the mainagricultural science knowledge networks in agricultural science and technology innovation, transformationand application of scientific and technological achievements has always dominated, universities, researchinstitutes play an increasingly important role in the network. However, in today’s deepening economicreform, cooperation in science and technology in the field of agricultural research also revealed various aspects of a serious gap, agricultural extension difficulties. The institutional level and the furtherintegration of spatial dimensions found the bodies of Agriculture Patent Cooperation quite different levelsof development of the eastern region is much higher than the central and western regions, from differentprovinces of view, has been formed to Beijing, Tianjin, the Yangtze River Delta, Pearl River Delta,different multi-polar growth pattern, and each increase of the driving mechanism of regional cooperation inYunnan, Xinjiang, Beijing, Tianjin, Xinjiang and other places to research institutes as the main drivingforce, the Yangtze River Delta region to enterprise-class organizations as the driving force, the PRD, andYunnan presents various agencies balanced growth trend. Furthermore, in addition to the policy ofeconomic reasons, some provinces in central and western regions of the use of their own advantagesinadequate, resulting in slow agricultural innovation patent cooperation and development.In terms of the dynamic mechanism of evolution. Different types of agricultural knowledgenetwork nodes (enterprises, universities, research institutes, government and other organizations orgroups) of active integration, as well as cooperation between nodes to produce the effect of pathdependence is an internal power network evolution. Economic globalization is one of the external powerknowledge network evolutions. Geographical proximity plays a decisive role in the formation and earlystages of development of knowledge networks, with the continuous development of the network, thenetwork structure is stable, the role of geo-spatial distance in the knowledge (especially tacit knowledge) ofthe flow and diffusion of waning, it is still an important factor. Organizational, social, cultural, institutionaland other close in the dissemination of knowledge and the flow can be reduced or even avoidedorganizational habits, socio-cultural and institutional differences in terms of rules and uncertainty is one ofthe external force of China’s agricultural scientific and technological knowledge network evolution.
