Owing to the shortcomings in the movement of collectivization, the ultraleft interruptions, and the fact that for a long period of time the Party had not shifted the emphasis of work to economic construction, the current material and technical bases for the collective economy are still comparatively weak. Meanwhile, there also are matters in need of improvement and perfection concerning systems and structure of the people’s communes, the weakest link being the management and administrative work. For a long time there have been no significant improvements and breakthroughs in implementing the principle of distribution according to work and in perfecting the system of job responsibility for production.
