چکیده
لباس پوشیدن و تهیه پوشش مناسب یکی از شاخص ها و برتری های انسان است. از آنجا که بانوان، نقشی اساسی در روابط مختلف هر جامعه ایفا می کنند و تمامی برنامه های اجتماعی، فرهنگی، سیاسی و اقتصادی با عملکرد و پشتیبانی آنان به نتیجه مطلوب خواهد رسید، انتخاب نوع پوشش آن ها از اهمیت ویژه ای برخوردار است. از آنجا که حجاب در دین اسلام و کشور ایران به عنوان یک کشور اسلامی جایگاه ویژه ای دارد و علاوه بر آن اثرات بسزای اقتصادی و فرهنگی در زندگی فردی و اجتماعی دارد، این مطالعه با استفاده از داده های دوره زمانی 1369-1399 الگوی سیستم تقاضای تقریباً ایدئال (ADIS) را برای چهار نوع کالای حجاب شامل چادر مشکی، چادر نخی، مانتو، روسری و شال در ایران با استفاده از روش پانل دیتا به صورت تک معادله ای و سیستمی برآورد می کند. بررسی ها نشان می دهد با توجه به معیار خوبی برازش، قدرت توضیح دهندگی مدل سیستمی بیشتر از تک معادله ای است. درنهایت براساس نتایج، با افزایش درآمد مردم، تمایل آن ها به سوی کالای حجاب باکیفیت تر می رود که این موجب افزایش سهم مخارج کالاهای حجاب می شود. با مقایسه کشش ها در هردو برآورد می توان به این نتیجه رسید که سهم مخارج کالای روسری و مقنعه به تغییرات درآمد حساس تر است.Economic Review of Hijab good with ADIS method
Dressing and preparing suitable clothing is one of the indicators and superiority of humans. Since women play an essential role in the various relationships of every society, in other words, all social, cultural, political and economic programs will achieve the desired result with their performance and support; Therefore, choosing the type of their cover is of particular importance. Because hijab has a special place in the religion of Islam and Iran as an Islamic country, and in addition, it has significant economic and cultural effects on the social life of individuals. One of the ways to investigate the place of hijab in the society is to investigate the behavior of consumers. The utility function reflects the consumption behavior and preferences of consumers, and by using it, it becomes possible to analyze the individual's demand structure. In this regard, the analysis of the demand structure and household consumption pattern is very important for the goals of economic activists, so that the policy makers and planners use its results to predict the future situation and finally, by evaluating the past policies, it is the basis for detailed planning. It will be provided for them for favorable conditions in the future. On the other hand, producers and other market agents need to forecast demand in order to plan and design their production and sales, and demand elasticity is important for this reason.
In this study, using data from the period 1990 to 2020, the model of an almost ideal demand system for four types of hijab goods - black veil, cotton cloak, mantle, scarf and shawl - in Iran using the panel data method as a single equation and A system is estimated. The results of this study show that according to the criterion of good fit, the system model has a higher explanatory power.
Based on the single-equation estimation, the elasticity of cotton tent, black tent, coat, scarf and mask was equal to 6, 22.04, 18.25, and 25.62, respectively.
The estimation of the system model in terms of the significance of the coefficients is the same as the single-equation model. According to the system model, the income elasticity of the cotton tent, black tent, coat, scarf and mask is equal to 6.33, 17.56, 18.44, and 19.32, respectively. The elasticity and sign of the coefficients of Manto are substitutes for the black veil and the cotton veil and have a complementary relationship with the other hijab products mentioned in this research. The black chador has a complementary relationship with the cotton chador and the shawl and scarf.
Based on the obtained results, both the systematic estimate and the single-equation estimate have a positive income elasticity, which indicates that with the increase in people's income, they go for higher and higher-quality hijab goods, which causes an increase in the share of expenditure on goods. It becomes a veil. By comparing the elasticities in both estimations, it can be concluded that the share of expenditure on hijab, headscarves and masks is more sensitive to income changes.
