Great work Jiahong. Your page is a long but very interesting read. GDP vs centrality in country's top-corporates, who would have thought that :-). Here are couple of queries/suggestions:

You say corporate graph is like social graph in your context. Now social graph is easy to get these days, but how to get such graphs. The linking criteria you mentioned is often a private information. How the graph qualifies in terms of truly reflecting the relatedness between companies? any way to measure this?

Betweenneess Centrality one 'e' extra :-)

Hi Prithu,

Good questions! The linking criteria is based on board member information, which should be public for companies listed on stock exchange. The result of graph is compared to profit ranking, which is frequently used to rank companies, with the help of rank correlation algorithm. And higher correlation between two ranks means graph based result will be more accurate. Hope these answers helps, if you have further questions, please do not hesitate to contact me.

Best regards,

Jiahong Chen
