Your residency permit is bound to active employment (or study). You can certainly have four different employers in four years based on a single Z-visa. The problem is there is no way to "extend" a residence permit in China and I learned this the hard way. Residence permits can only be renewed (pending continued or new employment), not extended. Whenever there is a gap between the current residency permit's expiration date and the commencement date of the next position, you will run into logistical problems.
Hypothetically, let's say your residency permit--arranged by College A--expires on August 8th, 2011 and your next position, with College B, commences on August 25th, 2011 (date on contract). Under ideal circumstances, the FAOs from both colleges would coordinate the transition so that the FAO from College B would apply for the transfer and renewal of your residency permit before your expiration date. If, for example, the FAO from College A is angry that you are leaving or the FAO from College B is lazy (or, more commonly, will still be on vacation during this 17-day gap period), you could easily run into problems. In such a case, you might very well have to return to China with a new Z-visa. You would need to be very proactive in such a situation to ensure that you don't have to reenter China on a new work visa.
You are not bound to one employer: Your residency permit is bound to active employment or study unless you happen to be one of the few foreigners in China who has an extended 5- to 10-year residency permit based on marriage, major business holdings, or special need (university professor or researcher who is making a major contribution to Chinese society).
If this reply doesn't address your specific situation, please try following-up with specific residency permit expiration and employment commencement dates.
Basically, if there is a large gap between the expiration date of your current residency permit and the commencement date of your next position, you will have to leave the country to reenter with a new visa.
I had the same situation happen to me back in the summer of 2008. My residency permit was going to expire in mid-August and my next position wasn't going to commence until the end of August. The new FAO was scheduled to be on vacation in August and didn't want to interrupt her holiday to attend to my residency permit problem. I ended up negotiating a "guanxi deal" with a local private school owner in which she would renew our residency permits in exchange for an extended period of website maintenance and teacher recruitment. Otherwise, I would have had to return to the United States and reenter China with a new Z-visa and the time involved in doing so would have cost me the new position.
