Flight arrive at 10.40pm at Shanghai Pudong airport. Will i miss last airport bus to Jingan? What can I take besides cabs?

If you can hurry up, you may catch the last bus, otherwise it is hard for you to catch the last bus.
Even though I do not think you need to catch a cab. From 23:00, there is the night line, so you can take the night line to reach Middle Zhejiang Road (Yan'an Road/People's Square) and then change to take a taxi.
