In detail, it mainly includes the relevant data of the general situation of the project, such as: building area, number of floors, floor height, structure type, use purpose, occupied area, etc.
The scale of production reflects the concentration of productivity factors such as labor force, labor means and labor object in investment projects. Its headings include "production capacity", "number of employees" and "original value of fixed assets". For industries with low level of manual labor and mechanization, it is generally measured by "number of employees"; For industries with high level of mechanization and automation, it can be expressed by "original value of fixed assets".
