Using the newest 150-km ranged 300mm projectiles, the PLAGF could theoretically hit ROC's Hsinchu Airbase and Hukou Army depot when firing from the edges of Pingtan Island. As with the 370mm projectiles, I don't think we know the exact range, except the export variant has a 220km range, which would be sufficient to cover most air bases around Taipei and Taoyuan.

The most recent export version of 370mm have 290km range.

The domestic version should be well in excess of 300km, people have thrown around 350km before which sounds reasonable to me.

This definitely makes sense to me. Hmmm I didn't catch the recent export variant update from 220km to 290km with regards to the 370mm caliber. Well, then China's MIC tell mentions 290km (to nominally abide by MTCR), you know that they are up to something interesting.

Please do not remove the weighted disc under any circumstances…

What would be the cost effectiveness of this? Wouldn't it just be easier to load a bomber with bombs and fly them to altitude before dropping them?

Air assets are inherently more expensive than lobbing rockets or shells over the strait. There are a limited amount of dedicated ground strikers and the PLAAF Bomber fleet has more pressing tasks than the stuff 300&370mm LRMLARs is dealing with. Besides, aircraft are of limited number and only conditionally scalable, where as ground based artillery is cheaper and allow higher saturated fires.
Aircraft are also threatend by enemy AA which Artillery is obviously not.

TL;DR
Aircraft are valuable and limited in numbers, Artillery not so much.

the cost of dropping munition from a plane is not the cost of the munitions alone.

it the cost of the munition + the labor of the pilot and support crew + the cost of operating the plane + the weighted probability of the plane being shot down.

the cost of rockets is the cost of the munition + the labor of the artillery crew (much cheaper than the pilot) + the cost of operating the artillery piece (much cheaper than a plane) + the weighted probability of the artillery piece being struck before firing by enemy forces (near 0 vs Taiwan).

so if the same target can be attacked by both artillery and air, its more effective to use artillery. some targets can't be hit by artillery, of course, and that's when air power is important.

Arty can also hit much more things because of the larger number of munitions it uses. You are lucky if you can deliver 8 munitions per aircraft per day. Which means just 8 fireteam positions or vehicles engaged if you are engaging a dispersed ground component. This is true most of the time in CAS. Even in interdiction missions some convoy dispersion ruin the effectiveness of air power. This happened in Yugoslavian wars. NATO airpower's efficiency plummeted after Serbia started to limit the size of logistical vehicle groups to 3.

Dropping cheap 3rd gen guided bombs (JDAM etc...) from aircraft would indeed be cheaper than using 370 mm guided rockets (if we are going to use NATO terminology strictly these rockets are small ballistic missiles) but the risk of losing the aircraft and the number of usable munitions tip the balance in favor of rocket artillery.
