I looked on the sinodefence website and it said the PLAAF is still looking for a replacement for the Q-5, though nothing has been found yet. J-11 production has stopped at 100 aircraft. The J-7 and J-8 are both still in production and are being upgraded well into the next decade. The J-10 and J-11/ SU-27/30 will not replace the Q-5, J-7 or J-8. A replacement for those has yet to be found. The H-6 bombers which number from 60-120 jets still receive upgrades until a new replacement is found. The PLAAF is not going to downsize but they are trying to modernized though stopping J-11 production at only 100 aircraft does not help.
Sinodefence is fine and it does the best job it can, with so much info about chinese forces is based on educated guessing, as theres little transparency from the govt. It pays to pay attention to last update dates on various pages, though. For example, the J7 info hasnt been updated in some 14 months, during which it was reported that j7 production for plaaf has ceased. Thats something that was expected, even sinodefence article says so, that production would cease in favor of extra j10 planes in a few years.
Like someone said before, j11a production has ceased but only in favor of more advanced model, which is currently being deployed in limited numbers within plaaf for testing purposes. Full scale production is expected to begin within a year or two. With Plaaf having over 300 j8s of various age, some of which are old enough to warrant replacement, it can safely be said that the new j11b will in fact replace some of the older j8s. Of course the newest ones will not be replaced, but will probably stay in service for another decade or two, until jxx comes along.
Same thing with j7s - there are new ones and not so new ones in service. Squadrons with older ones are getting replacement planes - j10s. But its a slow process. Unlike US did with f16s in mid 80s, china builds perhaps two dozen j10s a year, with little prospect of tripling that figure any time soon.
Number of all the combat planes produced in china combined may not be so low, but newest ones like j10, j11b or jh7a certainly wont get fielded by the hundreds in the coming years - so there cant be any talk of full replacement of older models. But gradual phaseout of older airframes - yes, that is certainly what is going on right now.
