عنوان مقاله [English]
The purposes of this paper are to determine the most frequent topics of dissertations in the field of urban and regional planning at Shahid Beheshti University )2006- 2016); to outline the co-occurrence of the topics in these theses, and to compare them with the most important problems in this field. The co-occurrence of 181 keywords was analyzed using centrality indicators. Urban and regional challenges were extracted by content analysis. Finally, a comparison between these challenges with the central subject of the thesis was conducted. The results showed that, first, “sustainable development” is the most widely used keyword in these theses that also acts as a connecting factor to other concepts; The five most common keywords except to “sustainable development” are evaluation, urban regeneration, distressed areas, and tourism. Comparing the central keywords with the urban and regional planning problems indicates that subjects such as water crisis and air pollution, weakness of the compensation regulations, shortcomings of urban transportation systems, and urban housing are topics that have been ignored in the theses. Although the subjects of the theses are highly relevant to the challenges of urban and regional planning in the country, the topics are affected by the official policies, and lectures,.
