The Economic Analysis Of Potato Production In China

China is the largest country of potato production in the world.There is a big market for China to develop it' s potato industry.But the potato products especially processing products of china are scarce of international competition.The domestic market and international market of potato will connected with each other after Chinese entry into WTO, then potato products with high quality made by developed countries will pouring into and occupy domestic market,and this will be a strong impact to Chinese potato industry.So,it is very necessary and impendency to change the condition of Chinese potato industry.But the techniques of potato production in China are get behind developed countries and this become the obstacle that preventing Chinese potato industry to get better.So,my research choose the process of Chinese potato production as our object.This dissertation adopts and combines normative analysis together with positive analysis,inductive analysis together with comparative analysis,qualitative analysis together with quantitative analysis to analysis the process of Chinese potato production based on investigating andcollecting a great deal of data and information.This dissertation set up the frame of Chinese potato production analysis base on the theories of many former researchers first.In the guiding of the frame,the dissertation describing the status quo of Chinese potato production and Chinese potato industry,and then analyzed the comparative advantage of Chinese potato production and international competitiveness of Chinese potato products,analyzed the economic efficiency of Chinese potato production by input and output analysis and TFP analysis,analyzed the influencing factors of Chinese potato production by qualitative and quantitative analysis,summing up good potato production experience of developed countries.Base on those analysis,the dissertation put forward advice and countermeasures tor the development of Chinese potato production.The main results as follows:1.The condition of international competitiveness of Chinese potato products.As to the international competitiveness of potato price,th unprocessed potato products had competitiveness because of low price level,primary process products and deep process products had no competitiveness in their main export country market.As to the international competitiveness of potato quality,the quality of deep process products elevate fast in theirs export country market and had competitiveness,the quality of unprocessed products scare of stabilization in their export country market,the quality of primary process products descend in their export country market and scare of competitiveness.As to the resource of potato breed,Chinese potato breed scare of competitiveness compare to other countries.2.Domestic regional comparative advantage.The results of AAI analysis of twenty-two provinces from 1991 to 2006 shows that the north region and southwest region had comparative advantage.Comparing to the national average production level,Qinghai,Ganshu,Guizhou,Yunnan,Ningxia,Chongqing,Neimenggu,Sichuang,Shanxi all had comparative advantage from 1991 to 2006.Liaoning,Xinjiang,Hunan,Hebei,Jilin, Guangdong,Xizang,Anhui,Jiangxi were scare of comparative advantage.3.Input and output analysis of Chinese potato production.(1)As to the condition of input,the cost of Chinese potato production experienced increase fast,then decrease and then keep stabilization from 1989 to 2005,the reason of cost decrease depend on the decrease of potato seed expense and the decrease of labour expense.The costs during production take on the trend of decrease,the reason lays on the decrease of sale costs.The expenditure cost become more and more small,it shows that the expenditure burden of peasants become more and more small.The difference of plating cost between those cities lies in that north region had smallest seed expense because they can buy seed from local place,but central region and southwest region had to buy seed from outside province becase of climate and geographical reasons.(2) As to the condition of output,potato output increased fast from 1989 to 2005.(3) As to the condition of output to input rate,the ratio of output to input range from 2.5:1 to 1:1 from 1989 to 2005,it's show that the ratio of output to input of potato production is high.The profit to cost rate increased first and than it decreased,and the peasant's profit decreased in two years.The difference of output to input of main plating cities shows that,the city of north region had low cost but low profit,the city of central region and southwest region had high cost but high profit.4.Analysis of TFP of potato production.We analyzed the increase of potato TFP using Malmquist index from 1989 to 2005.The results shows that,the TFP value of main potato plating cities take on the trend of increase,the average increase rate is 1.1%,but the increase is not stability and take on the feature of fluctual.The increase of TFP due to the progress of technical efficiency,the contribution of technical efficiency to TFP is 72.7%, the contribution of the technical progress is 27.3%.As to the distribution of potato plating cities,the TFP of the city ofWuhan,Jinan and Qingdao who are in central region increased fast,the city of Chongqing who is in southwest region is in the second place,and the TFP of the city of Wulumuqi,Huhehaote,Changchun and Lanzhou who are in north region increased slow.5.As to the influencing factors of Chinese potato production,seed was the most important fact;second,different plant mode and different plant density and different plant time haddifferent influence to the production and quality of potato;third,climate also an important fact;and the scale of acreage also had big influence to potato production and quality;the selling price of potato had positive influence to the increase of potato produce acreage in the past years.We make up the Cobb-Douglas function by using Panel Data model to analyze the influence factors of potato production.The results shows that the costs of potato seed is the most important factor to the yield.The cost of improving soil, other plating cost and the cost of labor has positive role to increase the yield6.The experience of main potato plating countries give us many useful reference.First, those countries are pay much attention to the production of potato seed and develop strict certification and detection system.Second,those countries all have complete seed production system.Third,they pay attention to the development of potato produce thchnology.Fourth,the management to potato industry of those countries are macroscopic. Last,the potato association of those countries play tremendous role.Based on the above analysis,the dissertation put forword some advice and countermeasures.Govemment should plan the potato plating area on the whole.We should develop leading potato enterprises to promote the process of potato industrialization. Correlative department should consummate the establishment or recension of Chinese potato quality standard and establish the manage statute of potato quality security and affirmance system of potato products as soon as possible.Government should establish the market permit and affirmance system of potato seed as soon as possible.Government should strengthen the scientific research of potato and perfect the techlogy service system of potato to improve the technical level of potato production.Correlative department should strengthen the work of potato seed market information,thus the producer can obtain related information timely.Government should increase the input to potato industry to improve the output level of potato production.We should improve the potato production management level to lower the cost of potato production.We should improve the degree of potato peasant organizations,play the role of potato association to promote the development of potato industry.
