Editor’s Note: Since the promulgation of the City Planning Law in 1989, city master planning, called also as city comprehensive planning, has become the primary component of China’s statutory urban-rural planning system and has played a significant guiding role in the development of Chinese cities amid the accelerating process of urbanization in the past decades. However, along with the proceeding of China’s reform and opening-up, especially the establishment of the socialist market-economy, there appeared some criticism on city master planning, for its inadaptability to the ever-changing market situation, low effectiveness in implementation, time-consuming in compilation and approval, etc., most of which are related to its all-inclusive contents and too detailed descriptions, as well as relatively weak strategical orientation. Because of these shortages, there emerged, at the turn of the new century, some new kinds of non-statutory planning, such as city strategic planning, which in certain cases and during certain periods even substituted city master planning to guide urban development. At the same time, the ambiguous interrelation with other planning made by various sectors, such as five-year socio-economic development planning, land use master planning, environment protection master planning, etc., also weakened the guiding role of city master planning, which finally led to the experiments of so-called “integration of three plans” or “integration of multiple plans.” Thus, for a considerably long time, reforming the compilation of city master plan and reshaping the role of city master planning by structuring a new spatial planning system have been a hot topic in both the academic and practical fields of urban planning in China. The practice of city master planning in Shanghai, Beijing, and other Chinese cities in the past years also showed the professional efforts in that direction, with more attention paid to the strategic orientation to long-term urban development. Recently, according to the institutional reform plan of the State Council, the duty of urban planning was transferred to the newly established Ministry of Natural Resources, showing the determination of the Central Government to unify the previously overlapped multiple planning systems by setting up a new spatial planning system. This will definitely influence the reform of city master planning. Nevertheless, no matter what happens, the status of city master planning in either the existing urban-rural planning system or the potential new spatial planning system should not be denied and its role of strategic orientation to urban development should be further strengthened.
