Introduction 
The issue of competitiveness is an important and central issue that is referred to as a means to achieve favorable economic growth and sustainable development. A city’s competitiveness depends on a set of factors that include the type of governance, global communications, social and economic infrastructure, the quality of human capital and the natural environment, the business environment, and the capabilities of local institutions. During the last few decades, the city of Sanandaj as the capital of Kurdistan province, with increasing population growth and migration, has led to the construction and many changes in the spatial structure, especially the skeletal-physical growth and expansion of the city in unfavorable natural locations. The spatial situation of the old fabric and the historical market in the center of the geographical gravity of the city and the loading of tourism-recreational potentials, especially in Abidar, Qeshlaq River, and the natural edges can be emphasized in determining the factors, the patterns, and indicators that are necessary to pay attention to address urban issues and especially competition The adaptability of the urban economy has made it necessary. While reviewing the concepts, approaches, and theories of urban competitiveness and urban regeneration, this research will provide patterns, themes, and indicators of sustainable urban competitiveness, emphasizing the economy-based procedure in sustainable regeneration management programs.
Methods and Materials
The nature of the current research methodology is developmental based on the result and descriptive-analytical based on the nature, purpose, and method. According to the problem of the present research, citations, indicators and criteria, and concepts and patterns extracted from the theoretical foundation’s section through content analysis and qualitative analysis technique (theme analysis) were examined. Also, the current situation of the studied area was examined with the multiple regression method as the main focus of the research. We applied content data analysis and coding, bibliographic software (VOSviewer), and software (SPSS20) in the title, abstract, keyword, text, and results of articles in the English language in authentic journals including articles or review articles, published in (ScienceDirect) and (Scopus) publications. A total of (623) documents containing one of the keywords of urban competitiveness, and economic regeneration were examined and studied in these scientific bases. Also, the statistical population (76) people through random sampling available includes organizations and institutions involved in urban regeneration and affecting the urban economy, as well as public and private institutions of Sanandaj city in connection with selected areas as study samples including (amusement park Abider mountain tourism has been determined as a macro sign and urban indicator, traditional market as historical identity, Qashlaq river and natural edges.
Findings
First stage: qualitative part; These results indicate that (ScienceDirect) 311 documents and (Scopus) 312 documents in total (623) valid scientific documents containing one of the keywords of urban competitiveness, economic regeneration have been examined and studied in these scientific databases. Finally, by reviewing (15) articles of valid scientific articles that had the most thematic and content relationship with the research title and the present article was subjected to final analysis. The highest number of articles and scientific documents published in this period is related to the year (2021) and related to research articles with (61.1). Publications (Sustainability Switzerland) have the most scientific citations based on the year of publication in the field of urban regeneration and competitiveness. The largest number of articles in this field in terms of geographical territory is assigned to America with (202) articles, followed by England with (96) and the United States of America with (90) articles. Based on the content and qualitative analysis and review of Table No. (1), the results of the coding show (55) criteria/indicators, (12) themes (content and procedures), and (5) the main components of “social, economic, environmental, political, administrative, physical. The results of the secondary analysis extracted from primary coding are reviewed in table number (2).
Second stage: Quantitative part
To prepare a questionnaire to investigate the identification of models, indicators/criteria, and concepts affecting the economic competitiveness of Sanandaj city and the selected statistical population through the Delphi method and the questionnaire tool, the statistical population (76 people) through random sampling available from employees and employees in organizations and institutions involved in urban regeneration and influencing the urban economy, as well as public and private institutions of Sanandaj city about selected areas as studied examples including (Abider mountain amusement and tourism park as a macro sign and urban indicator, traditional market as historical identity, Qashlaq river and natural edges). According to the combined method of research and determining the themes through qualitative content analysis, the number (12) of inferred themes from the first stage of analysis will be exploited and analyzed in the final analysis. The results of table number (6) also show that there is a significant difference in the theoretical mean (number 3) (p<0.05). Based on the model at the first level, the changing themes of urban economic competitiveness of the city have been investigated. In total, the themes of “Urban investment”, “Competitiveness of urban events”, “Competitive development of land uses”, “Competitiveness of urban tourism”, “Housing and economic competition”, and “Competitiveness in creating access in cities” the average have been assessed to be above the theoretical average of evaluation.  This is examined in detail in table number (7) and shows this matter.
Conclusion
The results of the analysis of the sources and the results of the questionnaire show that the most important categories affecting the competitiveness of urban economic regeneration are in the form of five components (social, management-political, economic, environmental, and physical). By examining and summarizing the theoretical basics and  and applying combined research method including; Qualitative and quantitative content analysis, we submitted (5) thematic keyword as the concept of “creating urban competition through event-oriented programs, investing in the city’s competitive attractions, investing in environmentally friendly industries, developing creativity and competitive innovation in entrepreneurship, Competitiveness at the level of location and housing”; (55) keywords as research indicators “attractiveness of urban historical areas, urban creativity, attractiveness and competitiveness, social structure of the city, urban dynamics, reduction of cultural aspects, urban dispersion, urban innovation, knowledge production , low capital, urban economic attractiveness, global economic competition, development of economic competition, competition between small and medium cities, economic and financial mechanisms, improvement of urban competition, job creation, capital attraction, housing price, promotion of public health, ecology, urban ecosystem , urban expansion policies, location, urban events, economic marginalization, competitiveness of cities, government monetary policy, competitive tourism destinations, business information technology, regional and urban inequalities, pedestrians, redevelopment of historical areas, access , regeneration, land redevelopment, spontaneous development, urban density, distance gone Urban influx, infrastructural investments, historical monuments, housing market, housing renovation, and urban expansion”; and (5) thematic keywords as research models “competition in urban innovation, competitiveness of urban tourism, and urban investment, and urban dispersion and urban competition. Factors of competitiveness in entrepreneurship, housing, and economic competition, the competitiveness of urban events, competition in creating access in cities, competitive development of land uses, the competitiveness of green development, livability investments based on competitive advantage, accumulation and location, and accumulation of activities. These have been extracted from the studies and the conceptual information and process have been presented in detail in the theoretical and conceptual framework diagram (Figure No. (6)).
