# How can I distinguish between those factors that affect supply elasticity and those that shift it?

How can I distinguish between those factors that affect supply elasticity and those that shift it? I am trying to make two regressions, one with the determinants that affect its elasticity and the other with the determinants that shift the curve. However, it seems that many of the factors are common, for example, the number of producers or technology. Any ideas?

• elasticity refers to how sellers react to change in prices. An increase by $x$% in prices leads to $y$% increase in production. $y/x$ is elasticity. In this it is assumed that technology (production function) doesn't change. An example of shift would be switching to a new technology of production (such as using an advanced machine).
