The results show the main factors that influence farmers; behaviors on agricultural inputs are whether they have the assistance of agricultural technology personnel; the choices of plantation; non-agricultural income; area of land management; the expectation on land ownership, whether it has township enterprises and the proportion of the non-agricultural labor forces and some other factors. The influencing degree of these factors descends from strong to weak. On the strength of the study results, the countermeasures on increasing local farmers' inputs on agricultural technology are put forward from the aspects of stabilizing rural land property, establishing scientific land transfer mechanism and intensifying the governmental functions of agro-technical station.展开更多

The generalization makes it easier for the model to handle many problem instances. A linear program is used to solve the new model. An example is given to show that the new model can handle classes of problems that the original model cannot handle.展开更多

Science-based measurement of technology content in and structure of exports should be conducted using production process data. Using world input-output tables(WIOTs) of 1995-2011, this paper developed a new method for measuring the export technology content of China and other major countries. Our research findings suggest that, since 1995, there has been some technology upgrade of Chinese exports. China's overall and sector-specific technology contents, and domestic technology contents and indexes all increased and demonstrated a weak convergence towards the average level of developed countries. Judging by the relative rankings of sector-specific technology levels, China is almost locked at the lowest level in the world, and cannot challenge the technological superiority of developed countries like the U.S. and Japan.展开更多

In view of these problems,the following suggestions were given to improve the innovation of agricultural technology in China. ( 1) Restructuring agricultural research institutes,establishing cooperative innovation centers,improving agricultural technological innovation system; ( 2) Specifying the direction of research projects,improving scientific research level of technicians,so as to improve the agricultural technological innovation capacity; ( 3) Improving promotion and service stations in towns,organizing technological service teams of agricultural universities and colleges,establishing agricultural technological promotion systems; ( 4) Increasing input in agricultural technological innovation by attracting government input,enterprise investment and other financial support; ( 5) Cultivating more talents of agricultural technology,training leading agricultural technicians,grassroots agricultural service staff and practical talents.展开更多
