چکیده مقاله :

سبزیجات بخش مهمی از سبد غذایی خانوارهای ایران را به خود اختصاص داده است. هدف پژوهش حاضر تحلیل قدرت بازاری و شناخت رفتار بازیگران زنجیره عرضه محصولات منتخب سبزیجات است. بدین منظور داده‌های هفتگی محصولات منتخب سبزیجات شهر تهران در دوره زمانی 95-1390 مورد تحلیل و بررسی قرار گرفت. یافته‌های تجربی مطالعه دربرگیرنده دو نتیجه اصلی است. نخست آنکه میان دو سطح عمده فروشی و خرده فروشی رفتار رقابتی وجود دارد و قدرت بازاری عمده‌فروشان در زنجیرۀ توزیع محصولات فسادپذیر همانند سبزیجات بیش از خرده‌فروشان است. دوم آنکه ساختار بازار سبزیجات متفاوت از یکدیگر بوده و واکنش بازیگران زنجیره عرضه به تغییرات قیمتی ایجاد شده در هر حلقه در همه محصولات یکسان نیست. لذا پیشنهاد می‌شود که در سیاست-گذاری‌های پیشرو به قدرت بازاری عمده فروشان در زنجیره توزیع سبزیجات و همچنین تفاوت ساختار بازار و نقش هر یک از بازیگران زنجیره و نوع واکنش آن‌ها به تغییرات در هر محصول توجه شود.

چکیده انگلیسی:

Vegetables are an important part of the food basket of Iranian households. The purpose of this study is to analyze the market power and identify the behavior of supply chain actors in selected vegetable products. For this purpose, the weekly data of selected vegetable products in Tehran in the period 1390-95 were analyzed. The experimental findings of the study include two main results. First, there is competition between the two levels of wholesale and retail, and the market power of wholesalers in the distribution chain of perishable products such as vegetables is greater than that of retailers. Second, the structure of the vegetable market is different and the reaction of supply chain actors to price changes in each loop is not the same in all products. Therefore, it is suggested that in leading policies, the market power of wholesalers in the vegetable distribution chain, as well as the differences in market structure and the role of each of the chain actors and the type of their reaction to changes in each product, should be considered.
