Your suggestions are ok.
But how to select the pasteboard and paste our objects by script.
I have finished the task by moving the objects to the pasteboard.
Sorry for my late reply....
Generally speaking you should not be using paste and the clipboard in scripting. Instead you should use the .duplicate() method to copy an object; you can specify the destination of the duplicate so you can provide the coordinates of the location on the pasteboard.
If you use the clipboard, your script will be slower, and it will not preserve the user's prior clipboard contents.
