It is very important for policy makers and industry to make it clear . many investigates have been conducted in many countries while it is lack in china this paper reports a study of the consumer ' s perceptions and attitude toward gm food and their determinants based on a public survey conducted in twenty - one supermarkets of beijing 本文通過對北京市區21家超市的顧客進行抽樣訪問,運用probit模型對調查結果進行分析,闡明了消費者對生物技術和轉基因食品的各方面尤其是安全性的認識,分析了消費者對轉基因食品認識和態度的決定因素。

The empirical analysis , using probit model , showed that the extension efficiency of the technique was obviously affected by following factors : income and cost , yield increase , farmers “ age and education , non - agricultural income , farmer ' s social status , distance from town , frequency of farmers “ contact with media and agricultural technicians 運用probit模型對超高茬麥田套稻技術推廣的影響因素進行分析,結果顯示畝增收節本、畝增產量、戶主年齡、戶主受教育時間、非農收入、是否干部、離鎮距離、媒介頻率、與農技人員接觸次數對該技術的推廣有顯著影響。

Literatures indicate that logit model , logistic model , probit model , mlr , cluster model , option model , proportion risk model , and discriminant analysis are the main effective methods and models when researching the determinants of residential mortgage default risk 通過梳理文獻發現, logit模型、 logistic模型、 probit模型、多元線性回歸、聚類模型、期權模型和比例風險模型、判別分析是研究個人住房抵押貸款違約風險影響因素時采用的主要方法和模型。

The probit models show that while the advantage of men to women in employment opportunities persisted over the period of survey under analysis , the magnitude of the gender effect weakened . however , educational attainment has become a basic factor in employment Probit就業概率模型的結果顯示,盡管在調查期內男性相對于女性有持續的就業優勢,但性別的影響程度減弱了;而教育逐漸成為決定勞動就業的主導因素。

To analysis the factors impacting the perceptions and attitude of consumer , probit model is used to compute the survey data . we find that consumer has a general knowledge toward gm food , but there are lots of misunderstandings 影響消費者對轉基因食品態度的主要因素是對轉基因的認識程度,而其他社會學因素和經濟學因素只能通過影響消費者對轉基因食品的認識進而間接影響消費者對轉基因食品的態度。

Surveys were carried out in three sample villages in yangzhou city , jiangsu province . in this study , the probit model was applied to conduct an empirical analysis of factors related to extension of the technique , and following results were obtained 以揚州市三個村為樣本,在實地調查得到的橫截面數據的基礎上,運用probit模型對影響該技術推廣因素的作用方向和作用程度進行實證分析。

In accordance with the specific features of the objects under model observation , the models were estimated by ordered - probit and 0 - 1 probit respectively for the consumer acceptance and willingness - to - buy will concerning gm foods 根據模型考察對象的具體特征,研究中分別采用有序多項選擇模型( ordered - probit )和二元選擇模型( 0 - 1probit )估計了消費者對轉基因食品的接受程度和購買愿意。

Using probit model , the decision of off - farm employment was analyzed in chapter four , accompany with the analysis of decision on labor participation and agricultural work participation 第4章對健康與非農就業參與率的關系進行研究。作為比較,本文選取了總和參與率和種植勞動參與率的決定因素進行了分析。
