چکیده مقاله :
The purpose of this study was to investigate the peripheral factors on reducing the consequences of the targeted subsidies from the view point of greenhouse owners of Semnan Province, Iran. The population of the study comprised greenhouse owners of Semnan Province. The sample size was calculated using Cochran formula and encompassed a number of 287 greenhouse owners. The main research tool used in this study was a questionnaire. SPSS v21was used to analyze the data obtained through the questionnaires. Based on hypotheses and theories, questions were designed, and after testing validity and reliability (based on the dependent variable Cronbach's alpha was calculated equal with 87.8) indices, modifications were performed. To examine the hypotheses of this research, the correlation coefficient was estimated, and a multiple regressions analysis was run. The results showed that current expenses, using the proper structures for constructing greenhouse, method of fuel use, the perfect place of heaters, and the use of skilled workers in the greenhouse had a key role in reducing the impact of targeted subsidies plan (dependent variable) on greenhouse owners. These variables explained 40.2 per cent of the variance in the dependent variable.
این مطالعه با هدف بررسی نقش متغیرهای محیطی بر کاهش پیامدهای طرح هدفمندی یارانهها بر گلخانهداران استان سمنان انجام شد. نمونه آماری شامل 287 گلخانهدار بود که از طریق فرمول کوکران تعداد آنها تعیین گردید. برای تجزیه و تحلیل دادهها از نرم افزارSPSS21 استفاده گردید. ابزار اصلی پژوهش پرسشنامه بود که براساس مبانی تئوریک طراحی گردید و پس از اصلاح محتوا با فرمول کوکران مقدار آلفای آن 87/7 محاسبه شد. از همبستگی و رگرسیون برای تحلیل فرضیهها استفاده شد. نتایج نشان داد کاهش هزینههای جاری، استفاده از سازههای مناسب، استفاده درست از سوخت، مکانیابی درست وسایل گرمایش و استفاده از کارگران ماهر بیشترین نقش را برکاهش پیامدهای هدفمندسازی یارانههابرای گلخانهداران ایفا میکنند که مقدار 2/40 درصد از واریانس متغیر وابسته را تبیین میکنند.
