首先你要明白,定语从句中去掉which 和that这种连接词后,句子一定要是不完整的,所以你这个句子你看看,去掉which后还是一个完整的句子,就不是定语从句了.你可以这样说：Furthermore,with the development of the productivity,the residents can live a more abundant life under the influence of the model.
如果非要用定语从句,你可以说：Under the influence of the model,the citizens will lead a more abundant
life, which comes from the rapid development of productivity.
希望我的回答对你有所帮助,谢谢!
