Although this structure, given the limited economy of rural areas and their specific features, could work in the past, considering the expansion of the markets and their undeniable effect on rural spaces, and also considering many unsustainabilities in several natural, economic, and social dimensions, it can no longer guarantee sustainable residences and occupations in rural areas. Most of the scholars in the area of development have proposed the diversification approach within the framework of sustainable rural development. Based on this theory, diversity is a necessary factor for maintaining the sustainability of rural economy and development; it is suggested that following this approach will contribute to the stability sustainability of economic structures. Based on this theory, sustainability is created and maintained when a system has numerous and diverse elements; the more diverse a system is, the more ability it will have in reducing internal and external discrepancies. This will * Responsible Author: magh30@um.ac.ir Rural Research Quarterly Vol. 5, No. 2, Summer 2014 4 result in sustainability, dynamicity, and stability during long periods and in different places not only against internal tensions but also when external challenges are faced. In addition to investigating level of sustainability in rural residences in Mashhad, this study aims to discover whether sustainable villages are the economically diverse ones. It also aims to find out what relationship exists between levels of sustainability and diversity of economic activities. The significance of this study first lies in the fact that it uses cluster analysis which can provide a new model for investigation of sustainability; second, it investigates sustainability in relation to diversification. Methodology The method of study is descriptive-analytic. The data needed in this study was collected using survey (Village and Family Questionnaire) and library research methods. The population under investigation in this study included the rural residences in Mashhad, and the unit of analysis was village. The sample size was determined in two levels for village and family using the Cochran formula. The number of sample villages and families was determined to be 34 and 350 respectively. The sample villages were chosen using the stratified sampling method. To ensure the content validity of the questionnaire, the opinions of the scholars in the areas of geography and social sciences were used as the reference. In addition, to measure the reliability of the questionnaire, alpha Cronbach formula was used. In this study, the sustainability of rural residences was the dependent variable and the diversity of economic activities played the role of independent variable. To measure sustainability, several techniques exist which can be used differently based on the type of study. In the present study, cluster analysis is used to quantify sustainability and classify residences. The collected data were analyzed and interpreted using SPSS and Excel. Statistical tests used in the present study include cluster analysis, variance analysis with the Tukey test, and Pearson correlation. Data Analysis In the present study, to measure and assess sustainability, cluster analysis, which is statistical method to determine homogeneous clusters, was used. The created Rural Research Quarterly Vol. 5, No. 2, Summer 2014 5 clusters were labeled sustainable, semi-sustainable, and unsustainable based on the value of the sustainability index. The results of cluster analysis revealed that 9% of the villages under investigation were sustainable in economic, social, and environmental dimensions; 44% were semi-sustainable, and 47.1% were unsustainable. In fact, 91.2% of the sample villages were unsustainable or semisustainable. To compare the mean of the diversity of economic activities in sustainable, semi-sustainable, and unsustainable groups, Fischer method was used for conducting a unilateral variance analysis (F test). Since the level of significance for this test was less than 0.05, one can say that the mean of the diversity of economic activities for the three groups was not the same; in other words, there was a significant difference between the mean of the diversity of economic activities among these three groups. According to the results of HSD test, the mean of the diversity of economic activities in the unsustainable, semi-sustainable, and sustainable was 27.5, 30.7, and 38.6 respectively. These results determine the answer for the first research question in this study. In fact, sustainable and stable villages are those which enjoy higher levels of the diversity of economic activities. To investigate the relationship between levels of sustainability and diversification, Pearson correlation was used. The correlation coefficient found between the abovementioned variables (0.77) shows that there is a positive and direct relationship between them. In fact, the increase in the level of sustainability is accompanied by an increase in the diversity of economic activities. This shows that the sustainability of rural residences is deeply affected by the diversity of economic activities in an area. Therefore, the answer to the second research question is clear: more diversity in economic activities results in more sustainability in rural residences. Conclusion The results of the survey and theoretical investigations done in the present study show that the diversity of economic activities in rural areas meaningfully contributes to the sustainability of these areas. The results of the present study are consistent with those of the studies conducted in South Asia (Feldman, 1999), West Africa (Ackah & Medvedev, 2010), and China (Liu et al., 2003). It can be argued that a Rural Research Quarterly Vol. 5, No. 2, Summer 2014 6 society with a diverse economy is more likely to become stable and sustainable. This issue has been considered by international organizations, developed countries, and some of the developing countries (China, India, Malaysia); and it is necessary to include this in the formulation of policies which are developed for rural areas in the country because simply continuing the current trend without any reforms and without paying attention to diversification will certainly result in the increase of unsustainability in rural residences. ی یکی از رویکردهای مهم توسعۀ پایدار روستایی «تنوع‌بخشی فعالیت‌های اقتصادی» است. تنوع، پیچیدگی ذاتی سیستم‌ها را افزایش می‌دهد و از این طریق فرایندهای درون آنها را تقویت می‌کند. مطالعۀ حاضر با روش توصیفی ـ تحلیلی به تبیین رابطۀ تنوع‌بخشی فعالیت‌های اقتصادی و پایداری سکونتگاه‌های روستایی شهرستان مشهد می‌پردازد. جمع‌آوری اطلاعات، مبتنی بر روش اسنادی و پیمایشی بود و نمونه‌گیری به‌روش طبقه‌ای تخصیص‌یافته صورت گرفت. با استفاده از تحلیل خوشه‌ای، سطوح پایداری سکونتگاه‌های روستایی در سه بعد اقتصادی، اجتماعی و زیست‌محیطی با 36 شاخص در مقیاس نسبی تعیین گردید. نتایج حاصل از 34 پرسشنامۀ آبادی و 350 پرسشنامۀ خانوار نشان می‌دهد که فقط 8/8 درصد سکونتگاه‌های روستایی بررسی‌شده، ازنظر ابعاد سه‌گانه پایدار بودند و 1/44 درصد آنها در گروه نیمه‌پایدار و 1/47 درصد در گروه ناپایدار قرار داشتند. بررسی نتایج حاصل از آزمون تحلیل واریانس یک‌طرفه نشان می‌دهد که میانگین نمرۀ تنوع فعالیت‌های اقتصادی در روستاهای پایدار 6/38، در روستاهای نیمه‌پایدار 7/30 و در روستاهای ناپایدار 5/27 است. به‌منظور بررسی دقیق‌تر رابطۀ بین پایداری و تنوع، از آزمون همبستگی پیرسون استفاده شد. بررسی‌ها نشان داد که رابطۀ بین پایداری و تنوع مستقیم و به‌میزان 77/0 بود، که ازنظر شدت قوی است. براساس مطالعة صورت‌گرفته، تنوع‌بخشی فعالیت‌های اقتصادی در نواحی روستایی می‌تواند پایداری سکونتگاه‌‌های روستایی را تقویت کند.
