Pushing on a string is a figure of speech for influence that is more effective in moving things in one direction than another – you can pull, but not push.
If something is connected to you by a string, you can move it toward you by pulling on the string, but you can't move it away from you by pushing on the string. It is often used in the context of economic policy, specifically the view that "Monetary policy asymmetric; it being easier to stop an expansion than to end a severe contraction."

“As I came home through the woods with my string of fish, trailing my pole, it being now quite dark, I caught a glimpse of a woodchuck stealing across my path, and felt a strange thrill of savage delight, and was strongly tempted to seize and devour him raw; not that I was hungry then, except for that wildness which he represented.”
—Henry David Thoreau (1817–1862)
