While I can't offer knowledge on a full explanation of differences I can provide some insight.

In WW1 the core European powers had been ruling their regions for quite some time. Many countries that formed after WW1 had not been existent before. So for some people living in occupied zones they didn't really have something to rise up against. Poles for example had been living under a German Empire. When Russia briefly took territory the Poles were now just living under a Russian Empire. They didn't yet have a sense of nationality and by the time they had established a sense of nationality the Russian Revolution was in full swing so they were fighting in organized armies for independence.

In the west trench warfare had bogged down fighting. Some Belgium sabotage occurred but since most of the fighting was trench warfare there was little partisan activity to be done. In France the majority of men in the regions captured had either fled, been captured, or were working to sustain their families.

In WW2 the stakes were greatly different. Quickly after the violence, aggression, and sheer wickedness of the Germans was discovered people rose to fight. Also since the Germans had a long line, Eastern Europe, there was more room for partisan activity. Also it was way more crippling on the German army. Blown railways in Eastern Europe delayed valuable resources and reinforcement from reaching the front while in France the full efficiency of the countries productivity could not be utilized due to partisan activity. In Eastern Europe mainly though the sheer brutality of the Germans drove the population to resist. In France and other countries though the population resisted through different means some through sabotage most through obstruction, failure to comply, espionage, and protest. When the allies landed in Western Europe resistance fighters greatly contributed to their advance. Mainly I would want to end that the core difference in partisan activity was that in WW1 there was not a huge need to resist the occupying power due to treatment and lack of nationality in some Eastern countries. In WW2 though the treatment of local populations by the Germans, mostly in the east, drove them to fight. They were being killed, rounded up in ghettos, oppressed, the people had reasons to fight and were also desperate to survive and get revenge against the Germans. The mass of the German advance made railway lines vulnerable so hitting tracks and supply depots took a huge effect on German logistics.
