This is an extended usage of word gridlock specifically in economics to describe the common situation that occurs in the competition within an industry or a company.
In the business as in traffic, when gridlock happens, an industry is unable to function at a healthy level, which can be highly problematic and costly.
If there are several groups with conflicting interests exist within one company competing to gain the control and power, this can create a situation in which business transactions can not be completed until the problem is solved.
If all the parties can cooperate, for example, companies can collaboratively invest in a sustainable way, the gridlock can be easily solved and the industry will function in a healthy way.
Naturally to solve this problem, it requires institutions within the industry or company to regulate rules and prevent the inefficient situation to happen.
