TITLE: CAUSAL ANALYSIS IN CHANGES OF LAST TWO DECADES OF IRANIAN CARPETS (Case Study Areas: Northern Khorasans, Razavi Khorasans and Southern Khorasans)

In many researches and studies related to Iran’s practical arts including carpets there are incomplete and incomprehensive analysis provided about them due to ignoring part of the dimensions and components of causality; considering the special place of Iranian carpets among the practical arts (Due to the combination of aesthetic, consumer and economic functions); the systematic recognition of these dimensions and components of conception and change of carpets in a specific historic and geographic area, can provide planners, product managers and producers with useful analysis patterns and explanations. This research explains the type and form of the influence of the dimensions and components of causality on the figurative, technical, quantitative, and also the process of the creation of a carpet in a region using an interdisciplinary approach and a descriptive-analytical method. This study contains information on both the carpets and weaving districts and the agencies which are active in the organizational production of carpets. The sampling method of the carpets and weaving districts, is the coincidental classified method and the agency sampling is the selective method and it is according to their experience, influence and the extent of their activities in the last two decades. The geographical area of this research are Northern Khorasan, Southern Khorasan and Razavi Khorasan. The results of this research indicated that the existence of a carpet in normal conditions, has a close relationship with its causalities; but changes and transformations of the carpet was mostly affected by the activity of said agencies in the recent period. The production agencies can be present as a dependent variable in addition to their independent variable role in a district; in this conditions the independent variable can be different causal dimensions or other competing agencies.
