Socialist world-system?

Dear list member

I am a Dr. candidate and study the world-system theory (Wallerstein). I
am looking for literature to the following subject:

Szymanski (1982) claims that the USSR and the CMEA countries composed a
autonomous (socialist) world-system that was linked to the capitalist
world-economy by 'luxury' or 'non-essential' exchanges. So far so good.
But is there a more elaborated description of the socialist world-system
available then "socialist mode of production in which rational and
democratic planning prevails"? I'm looking for any references to
"socialist world-system", "socialist world-economy(?)", and/or
"socialist mode of production". If anybody could send me some references
that would be great. Thank you very much!
