چکیده

با توجه به افزایش تقاضا برای محصولات چوبی در کشور و محدودیت منابع داخلی، واردات چوب و فرآورده‌های چوبی از اهمیت به­سزایی برخوردار می‌باشد. از جمله سیاست‌های داخلی که در بازار چوب وارداتی مشهود است، اعمال موانع تعرفه‌ای و غیر تعرفه‌ای است. اطلاع از واکنش تقاضاکنندگان در مقابل تغییرات قیمت می‌تواند در تعیین و اعمال میزان موانع یاد شده و یا کاهش آن‌ها حایز اهمیت باشد. لذا، در این مطالعه ضمن برآورد سیستم تقاضای تقریباً ایده‌آل درجه دو برای چوب خام، واسطه و نهایی وارداتی و چوب خام داخلی طی سال‌های1390-1361، شاخص رفاهی تغییرات جبرانی ناشی از کاهش تعرفه گمرکی انواع چوب محاسبه شده است. نتایج مطالعه بیانگر وجود رابطه جانشینی بین چوب‌های وارداتی است. همچنین، برآورد شاخص تغییرات جبرانی نشان می‌دهد که کاهش تعرفه انواع چوب‌های وارداتی منجر به افزایش رفاه گروه تقاضاکنندگان چوب می‌گردد و تغییرات مخارج تقاضاکنندگان چوب در نتیجه کاهش تعرفه گمرکی چوب واسطه وارداتی، بیشتر از دو گروه دیگر می‌باشد. با توجه به افزایش رفاه تقاضاکنندگان چوب که مجموع کارگزاران اقتصادی تقاضاکننده چوب وارداتی و داخلی می‌باشند، شاید بتوان توصیه نمود، تعرفه واردات چوب بر اساس یک برنامه زمانی کاهش یابد. در این برنامه زمانی لازم است مواردی مانند روابط بین انواع چوب و امکان تطابق صنایع وابسته مورد توجه قرار گیرد. همچنین، پیشنهاد می‌شود مدیریت واحدی بر هر دو گروه از چوب حاکم باشد تا آثار سیاست‌های اتخاذ شده در مجموع بازار چوب مورد توجه قرار گیرد.
