Study On The Differences Of Factors Influencing The Size Of Pigs In Scale

In recent years, the state issued a series of documents to stable hogs production and ensurethe hogs market supply.Since2011the Ministry of Agriculture issued six measures to stabilizehog production to ensure market supply documents,in2014and2015,the Central "Document" incontinuing to clarify the importance of the protection and safeguards related to hogs production.Influence of100-499head of the factors accounting for the highest proportion of the total size ofthe hogs slaughter, clarify the factors of the scale hogs supply the degree of influence, canprovide a stable reference proposal for the development of this scale hogs supply policy.Using the Multi-index double logarithmic model and20provinces panel data regressionwhich be divided into four groups, the results show that on a hog prices and feed costs per hogssperm newborn animal kilogram price is affecting hog supply factors. And related research is toanalyze different head100-499highest impact factors accounted for the proportion of hogsslaughter this scale, the study object grouping performed multivariate regression panel data, andthe newborn animal model variables introduced kilogram price.The main difference between the elastic set in: the hogs slaughter Hubei, Jilin Provinceand Anhui three previous period hog price elastic, Liaoning Province,14hogs slaughter hogprices for the previous period inelastic; Shandong Province hogs slaughter13the amount of thefine for each hogs feed costs elasticity is positive; hogs slaughter16provinces of Shandong andother newborn animal kilogram price elasticity is negative. Group differences in performancewithin the elastic elastic at the same value, the influence of different factors on the amount ofslaughter hogss.
