چکیده مقاله :
Given entrepreneurs’ special role in the economic growth and development, many developed and developing countries are attempting to motivate more number of people who have entrepreneurial characteristics towards entrepreneurship and entrepreneurial activities. The purpose of this research was to study the effectiveness of entrepreneurship training courses in Ilam Province, Iran. In this research a descriptive survey method was used. The statistical population consisted of 830 people that based on Cochran’s formula and by using proportionate stratified random sampling method 130 people were selected as the sample. The research tool was a questionnaire which its validity was confirmed by a panel of experts’ and its reliability was estimated using Cronbach’s alpha as to be 0.83 proving its high reliability. Data were analyzed by SPSS Software Package. It wasfound that participants’inclination towardsself-employment and entrepreneurship was increased after attending the courses. Also, significant differences were observed in participants’ readinessto start a business, their familiarity with entrepreneurship concepts and their ability to make a business plan before and after attending the courses.
هدف اصلی این مقاله برآورد کارایی فنی با استفاده از روش آنالیز مرزی تصادفی (SFA) و تحلیل پوششی دادهها (DEA) و همچنین تأثیر نهادههای بکار گرفته شده بر روی ریسک تولید گاوداریهای شهرستان زابل میباشد. برای این منظور اطلاعات از طریق تکمیل پرسشنامه در سال 1393-1392 جمع آوری گردید. نتایج نشان داد که که میانگین کارایی فنی گاوداریها با استفاده از روش SFA، 74/0 درصد و بکارگیری روش DEA و تحت بازدهی ثابت و متغیر نسبت به مقیاس بترتیب 55/0 و 63/0 درصد برآورد گردید. همچنین یک رابطه مستقیم و معنادار بین میزان تولید و متغیرهای سبوس و تعداد رأس گاو وجود دارد. برآورد عدم کارایی فنی حاکی از وجود رابطهای منفی و معنادار بین سن دامپرور و عضویت در تعاونی با عدم کارایی فنی است. نتایج ریسک تابع تولید نشان داد که شرکت در کلاسهای آموزشی ریسک را کاهش خواهد داد. در نهایت آموزش در رابطه با بکارگیری مصرف بهینه نهاده ها و بکارگیری مدیریت مناسب جهت افزایش میزان کارایی گاوداریها پیشنهاد شد.
