Marine science technology innovation provides power and guarantees for marine eco-civilization construction,which provides direction and material support for marine science technology innovation.Therefore,the coordinated development of the two is of great significance to the marine economy sustainable development in China’s coastal areas.On the basis of clarifying the connotations of marine science technology innovation and marine eco-civilization in China’s coastal areas from 2006 to 2019,the mechanism for their coordinated development was analysed.A comprehensive indicator system based on the connotation of the two was constructed,and the coordinated development relationship was empirically tested using the coupled coordination model and the panel vector autoregressive(PVAR)model.The results show that:1)the level of China’s coastal marine science technology innovation continues to improve,gradually forming the core of the development of marine science technology innovation in the north,east and south of Shandong,Shanghai and Guangdong;the level of marine eco-civilization development fluctuating upward trend,showing obvious spatial differentiation characteristics.2)The degree of coordination of marine science technology innovation and marine eco-civilization is growing over time.There is no causal relationship between marine science technology innovation and marine eco-civilization in the northern marine economic circle,but there is a two-way causal relationship between the two in the eastern and southern marine economic circles.3)Marine eco-civilization shows a significant positive and continuous impact on marine science technology innovation,and marine science technology innovation shows a long-term,continuous,fluctuating,and lagging impact on marine eco-civilization.The overall role of marine eco-civilization on marine science technology innovation is dominant,and there are significant differences in the impact effects of the two major marine economic circles. 展开更多

Innovative ability is an important indicator for judging the effectiveness of the national agricultural science and technology park construction. Based on the statistical data of four national agricultural science and technology parks built in Jiangxi Province, this paper constructs an evaluation system consisting of three first-level indicators, eight second-level indicators and 24 three-level indicators. Based on the combined weighting method, the comprehensive scores of the innovation capabilities of the parks are obtained. It is found that the gap in innovation capability of each park is wide, and the radiation-driven function has not yet appeared. It is necessary to promote the improvement of innovation capabilities by promoting the synergy and innovation of agricultural science and technology in the park, encouraging the park to construct agricultural technology business incubators, and building and improving innovation platforms. 展开更多

Sustainable feeding of the growing population in China without ecological destabilization is a grand challenge. In this populous country where agriculture is dominated by smallholder farming, developing innovative technology and translating scientific knowledge into action for smallholder farmers is a crucial step in addressing this challenge. Here, we present a novel approach for technology innovation and dissemination to achieve sustainable intensification in the fields of smallholder farmers. The Science and Technology Backyard(STB) is a hub in a rural area that links knowledge with practices to promote technology innovation and exchange. In this study, the framework and functions of STB are introduced, and the key implications for sustainable intensification across millions of smallholder farmers are explicitly stated:(i) develop innovative technology based on stated demands of farmers;(ii) disseminate technology by innovative social service models though combined top-down approaches with bottom-up measures to enable smallholders in rural areas. This paper provides a perspective on transformation of small-scale agriculture toward sustainable intensification in China and useful knowledge applicable to other developing countries. 展开更多

This paper carries out a questionnaire survey of persons in charge of the agricultural project in the " Eleventh Five-Year National Support Program" on the level of innovation in projects and the factors influencing innovation. After the linear regression analysis of the survey data,it is found that the factors influencing the innovation in agricultural science and technology projects include the level of innovation in scientific achievements,efficiency of research methods and creation of innovation environment. Through the variance analysis of the level of innovation and its influencing factors related to different innovators,it is found that there are differences in the statistical significance of level of innovation in projects among universities,research institutes,research and extension departments directly under the government,and enterprises; there are no significant differences in the understanding of factors influencing innovation,that is,different innovators basically have the same understanding of factors influencing innovation,but the assessment on level of innovation in projects completed is different to some extent.On this basis,this paper proposes the recommendations for further strengthening the level of innovation in agricultural science and technology projects in order to provide a theoretical reference and practical basis for the project managers to effectively improve the level of agricultural science and technology project management,and enhance the level of innovation in projects. 展开更多

From the perspective of economic system transformations and scientific and technological system reforms, this paper investigates the evolution of China’s national innovation system (NIS) during the 40 years of reform and opening up. It concludes that China’s NIS has evolved from weak to strong, from a follower groping its way onto the track of independent innovation with Chinese characteristics. China’s innovation system has experienced a trajectory from “introduction and imitation of complete sets of technology” to “market for technology and imitative innovation,” to “integrated and secondary innovation” and on to “integrated, secondary, collaborative and original innovation combined.” The path of independent innovation with Chinese characteristics is a natural choice of economic, societal, and technological development in the new era. 展开更多

By constructing a yardstick competition model of the performance equation,this paper analyzes the internal mechanism of local governments'competition of science and technology(S&T)expenditure in China.By using the Dynamic Spatial Panel Model,we analyze the competition empirically from five dimensions:geographical adjacency,geographical distance,administrative adjacency,administrative grade and economic distance.According to the results,the local governments'S&T expenditure showed a significant strategic competition phenomenon,that is,there is a“competition for innovation”,and the competition is more obvious between regions with close geographical proximity and administrative relations.“Competition for innovation”will be affected by political exogenous shocks such as those from the National People's Congress(NPC)of China;There is a“father-son competition”relationship between the superior and inferior governments.At last,the competition can promote the regional innovation significantly,which shows that“competition for innovation”is a kind of top-by-top competition.The conclusions may provide some useful suggestions for optimizing the relationship between local governments and promoting the construction of an innovative country. 展开更多
