Abstract:This paper,taking technology extension sector as the main research object,dicussed the extension performance of technological extension sector in mushroom main production areas from both objective and subjective aspects,then constructed theoretical model of influencing factors from extension sectors’ satisfactory evaluation on extension performance.The results of logit regression show that operating income and adequacy of extension expenses are the main influencing factors of performance evaluation.Sectors which have operating income are more satisfactory with their extension performance,the more adequate of extension funds,the better satisfactory evaluation; availability of technical training for farmers also have some effect:the departments which give farmers technical training have better satisfactory evaluation;the departments which are funded by government have better satisfactory evaluation; technology promoter ratio and external cooperation relating to the departments’ satisfactory evaluation are uncertain,but problems still exist:shortage of extension staff,the quality of staff are not high,the result of external cooperation can not meet the real technology requirement to farmers.Finally,this paper puts forward some suggestions including increasing the support to technical extention departments,guiding multi-stakeholder’s involvement in agricultural technology market,improving the quality of farmers and promoters and popularizing new technology badly needed by farmers.
