It does not.
Surface tension of a liquid exists due to the fact that the molecules are at a higher potential when they are at the surface than when they are submerged in the bulk. A liquid system then tends to minimize its total free energy in such a way that the surface molecules, given the opportunity, "dive". Other surface molecules must replace a diving molecule on the surface and this makes the surface shrink laterally. Correspondingly, when the surface is stretched, molecules that have a smaller potential in the bulk are lifted to the surface so that work must be done and a force is required to do the stretching.
On a solid, the molecules are constrained so that they cannot move freely. Hence, they cannot "dive". For the same reason they do not move laterally and there is no mechanism that could transfer the potential difference in the direction perpendicular to a surface into actions parallel to it.
In capillary processes it often appears as if a solid would have a surface tension. Many phenomena can be nicely explained that way, but this is only because there are forces acting between a solid and a liquid, and it is the liquid that is able to adjust to them.
In physics literature you would find "Shuttleworth's equation" relating the surface tension with the surface energy on a solid. This, however, has recently been shown to be incorrect (Surface Science, 603(1): 97-101.

Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
What does high surface tension cause water to do?
High surface tension causes water to behave as if its surface had an elastic membrane, which was stretched. Due to water's high surface tension, effects like tears of wine and rain water beading on a leaf or grass happen.
What is the priming and carryover?
Priming occurs when a boiler has a high dissolved solids content which increases the surface tension of the water. Steam bubbles breaking through this surface tension often carry water over into the steam outlet of the boiler. Priming, also known as foaming, is what causes the carryover.
Why does low-surface-tension-liquids-clean-better than high-surface-tension-liquids?
Low surface tension means high wetting as it represents low contact angle. It is therefore very easy for a low surface tension water / liquid to wet the surface ( usually solid) and get rid of the dirty in a same way a surfactant does unlike a high surface tension liquid which can't wett the surface containing the dirty....

Does the pH of water remain exactly neutral because of the high surface tension of water?
The pH of water is not related to surface tension.
What is special characteristic of water?
cohesion, strong surface tension, unique crystalline shape when it freezes allows ice to float (less dense), high specific heat

What is the reason the high surface tension of water?
The reason behind the high surface tension of water is hydrogen bonds. This very strong bond enables small insects to walk on the surface of water.

Does water have a low surface tension?
Water has a relatively high surface tension compared to other liquids, due to hydrogen bonding.
Does the pH of water remain exactly neutral because of the high surface tension of water?
The pH of water is not related to surface tension.
Which solution would provide the maximum support for a water strider which can move on the surface of a liquid?
A maximum support is offered by a liquid with a high surface tension.
What is responsible for high surface tension and high specific heat in water?
elfuichee
What causes the high surface tension and low vapor pressure of water?
Hydrogen bonding causes the inward force that minimizes the surface area of water, and the tendency of water molecules escaping this bond to become vapor is slim and/or slow, thus creating it's low pressure.
What special property of liquid is shown when an insect walks on the surface of water?
A high surface tension
