Different results for food output could be obtained by varying the assumptions regarding the proportions of plot devoted to pigs and vegetables. The simple model of Table IV assumes that if the plot was large enough (if the land required to grow fodder for one pig was less than the total plot area) at least one pig was reared. This is so for all examples of plot in Table III except one (the average plot in 6,750 households of Hopei). Relatively small plots were assumed to support one pig and larger plots two. The area devoted to pigs, therefore was first set, providing a residual area for vegetables. As already stated, not all pigmeat produced might be retained by the peasant for consumption. Virtually no evidence of delivery quotas, however, was discovered. Furthermore the number of pigs which could be privately reared was not entirely dependent on the supplies of fodder from the private plot; fodder could be purchased on the local market or from the State. Therefore the simple assumption was made that deliveries of pork were

The Economic Significance of the Private Sector 29 fulfilled by rearing pigs through buying in fodder, so that all the pork produced from the private plot's fodder is assumed to be available for consumption. The food output per head thus obtained is given in Table IV.
