Cluster Dynamics Measure: C_motion



[0] Users must cite two following papers:

​Paper #1. Min Jung Kim, Myles Shaver, and Russell Funk. Forthcoming. "From Mass to Motion: Conceptualizing and Measuring the Dynamics of Industry Clusters," Strategic Management Journal

Paper #2. Jushan Bai and Pierre Perron. 2003. "Computation and Analysis of Multiple Structural Change Models," Journal of Applied Econometrics, (18) 1-22.

(For those who use Code #1 only, cite Paper #1 only)



[1] Code #1
- Input file #1 (for line 8): Total number of population in a year-region. A csv file should have three columns that represent year, casa (or any region identifier), and population, respectively.

- Input file #2 (for line 26): Total number of the focal industry establishments (or employees) in a year. A csv file should have two columns that represent year and the focal industry establishments (or employees), respectively.

- Input file #3 (for line 57): Total number of the focal industry establishments (or employees) in a year-region. An excel file should have three columns that represent year, casa (or any region identifier), and the focal industry establishments (or employees), respectively.


[2] Code #2
- Users must download both "Clulster_dynamics.m.zip" and "Supp_files.zip," and then unzip and place them in the same folder. 
- Input file #1 (for line 13): zscores of the focal industry establishments (or employees) in a year-region (This file is the same with the output file from Code #1)


[3] NOTE: As code #1 is a simulation-based calculation, the resulting outputs (i.e., zscores, and cluster dynamics values based on the scores) would be slightly different each time a simulation is run).
