Abstract

Background and purpose
The city of Yasouj has experienced remarkable growth and development in recent decades, because a huge wave of villagers and residents of neighboring cities have migrated to this city to benefit from these services and facilities, and this has led to the development and expansion of the city of Yasouj more than ever before. It has happened that this city has not been able to respond to this rapid growth in terms of service, administrative, religious, economic, commercial, etc. functions and has caused an increase in spatial-social separation between urban areas. Therefore, the main goal of this research is to evaluate the effective factors in the physical-spatial development process of Yasouj city based on the theoretical framework of spatial justice. The difference between the present research and the previous research is that this research combines different analytical methods and uses up-to-date and diverse sources. , is trying to achieve a deeper understanding of the factors affecting urban physical-spatial development and spatial justice and provide practical and targeted solutions to improve the state of spatial justice in Yasouj city.
Methodology
The current study, with emphasis on quantitative, research strategy, tries to evaluate the factors in the development of Yasouj city. For this purpose, data has been collected using a Likert-made questionnaire. In order to estimate the validity of the questionnaire, experts (university professors) were used and the reliability of the study was evaluated using Cronbach's alpha of 0.89. The statistical population of this research includes all the citizens of Yasouj, who were asked randomly. The dependent variable in this research is the physical-spatial development of Yasouj city with the approach of spatial justice, and the independent variables include economic, social, physical-environmental, managerial-institutional dimensions. In order to check and prove the research hypotheses, structural equation modeling (SEM) was used by PLS3 software. The structural equation model identifies the internal relationships between variables and analyzes the effect of one variable on other variables. Its different stages include these steps: 1) interpretive structural modeling, 2) model evaluation and fitting, 3) structural model fitting and 4) general model fitting.
Findings and discussion
The results show the importance of four social indicators (with an effect coefficient of 0/355), economic (with an effect coefficient of 0/342), physical (with an effect coefficient of 0/491) and management (with an effect coefficient of 0/176) in the development of Yasouj city. In this survey, it has been determined that the least impact was on human development and management indicators, and the most emphasis was on establishing physical and socio-economic balance. Therefore, in the general conclusion, it should be stated that the development path in Yasouj city is a reverse path in the urban development theories of developed countries. This means that management, intellectual and human systems are considered as the heart of the urban planning system in most of the developed countries, and the physical and physical dimensions that are in accordance with the algebraic view of the city are less worthy of attention.
Conclusion
The requirement to achieve spatial justice in the city is to consider environmental-physical, social and economic dimensions, but Yasouj city in terms of diversity and urban vitality and spatial access, such as access and occupation of spaces, land use, access to urban services, the existence of urban facilities, Their fair distribution in the urban space and easy access of citizens is facing serious problems.
