Study On Impact Of Agricultural Inputs Prices Increase On International Competitiveness Of Citrus

China is a major producer and exporter of citrus in the world with a long history in citrus cultivation and various species of citrus. With the continuous deepening of the rural economy reform and the development of agricultural technology since the reform and opening up, the citrus industry has developed rapidly.It has been the major pillar industries of the rural economy in some areas of Fujian, Zhejiang, Guangdong, Jiangxi, Hunan,Hubei, Guangxi, Sichuan and Chongqing provinces (autonomous regions and municipalities). However, in recent years, at first, with the continuous expanding of citrus-growing area and the increasing of annual output year by year, citrus supply is structural surplus.This problem must be solved by adjusting industrial structure and product structure of the citrus and broadening international and domestic market;Secondly, the continuous increasing prices of agricultural inputs and RMB appreciation trend which promote the increasing of citrus production cost and the export prices result in weakening our citrus prices competitiveness to some extent. The government and citrus producers must make efforts from the macro and micro perspective to reduce the negative impact; Thirdly, with the improving of living standard, the competition on quality and brand become more imminent in the domestic and foreign markets.So producter is in an urgent need of improving varieties and quality, building brands and improve quality competitive. Therefore, studying and discussing the impacts of agricultural inputs prices increase on the international competitiveness of the citrus and making policies and measures undoubtedly have very important theoretical merit and practical significance on effectively preventing citrus production and export trade from declining and ensuring the sustainable, steady,coordinated development of citrus industry and keeping rural incomes increasing.Agricultural inputs prices and the international competitiveness of agricultural products are always not only the focus of the agricultural economics profession both here and abroad but also the main subject of the citrus industry economists.But the association between the former and the latter is failed to be noticed, neither do other scholars explore it. In order to study and discuss the impact of inputs prices increase on the international competitiveness of the citrus deeply, this article develops theoretical framework to have the theoretical analysis and empirical research on causality and mechanism of impact of agricultural inputs prices on the international competitiveness of citrus by varied methods. By the theories and principles of international economics,competitive economics, microeconomics, market price and new institutional economics,this article has a comprehensive interpretation on formation cause and manifestations of the international competitiveness of agricultural products,an in-depth analysis on agricultural inputs price formation mechanism,the correlation of agricultural inputs price and international competitiveness of agricultural products and a desperation on the causal relationship and mechanism impact of agricultural inputs prices increase on the citrus international competitiveness systemly,then draw conclusions and inferences to be an empirical test.This article studies the direction and degree of the impact of changing of agricultural inputs prices and the RMB exchange rate on international competitiveness of the citrus overall by building multiple linear regression models.The results show that the impact of agricultural inputs prices increase and RMB appreciation at different period on the international competitiveness of citrus overall is different and controlled.From the direction of impacts, there are more positive impacts of precious and current increasing of agricultural inputs prices on varied international competitiveness index of the citrus overall than negative impacts. On the contrast, there are more negative impacts of precious and current RMB appreciation on varied international competitiveness index of the citrus overall. From the degree of impact, the positive impacts of precious and current increasing of agricultural inputs prices on varied competitiveness index of the citrus overall are larger than negative ones. The negative impacts of precious and current RMB appreciation on varied competitiveness index of the citrus overall are larger than positive ones.This article researches and analyses the direction and degree of the impact of changing of agricultural inputs prices and the RMB exchange rate on international competitiveness of tangerine, orange,grapefruit, lemon and citrus fruit, nes by building multiple linear regression model and adopting the combing method of vertical comparison and lateral comparison.The results show that there are obvious differences and certain control among the impacts of agricultural inputs prices increase and RMB appreciation at different period on the international competitiveness of citrus in different species. From the direction of the impact, positive impacts of the precious and current agricultural inputs prices increase on varied international competitiveness index of citrus of different species is slightly larger than negative impacts; negative impacts of RMB appreciation on varied international competitiveness index of citrus of different species is more than positive impacts.From the degree of the impact,positive impact of current and previous prices increase on the varied international competitiveness index of the citrus of different species is more than the negative effects and degree of impact on lemon,orange and Tangerine is greater than citrus fruit,nes and grapefruit. Negative impacts of RMB appreciation on the varied international competitiveness index of citrus of different species are greater than the positive ones. The negative effects on lemon, orange and tangerine is greater than grapefruit and citrus fruit, nes.Taking tangerine and orange for examples, this article researches and analyses the direction and degree of changing of impacts of agricultural inputs price and the RMB exchange rate on the DRCC of citrus by constructing multiple linear regression model and adopting the combing method of vertical comparison and lateral comparison.The results show that increasing of the current agricultural inputs price cause DRCC of tangerine and orange decline. The increasing of the precious agricultural inputs prices results in the DRCC of tangerine and orange rise.Influence of current and previous agricultural inputs prices on tangerine is larger than orange’s; Current RMB appreciation led to DRCC of tangerine and orange rise and precious RMB appreciation led to DRCC of tangerine and orange decline and influence of precious and current RMB appreciation on DRCC of tangerine is slightly smaller than orange’s.Taking tangerine and orange for examples, this article researches and analyses direction and degree of impacts of agricultural inputs price and the RMB exchange rate on NSP of citrus by constructing multiple linear regression model and adopting the combing method of vertical comparison and lateral comparison.The results show that the increasing of current agricultural inputs price cause NSP of tangerine and orange rise. The increasing of the precious agricultural inputs prices leads to the NSP of tangerine and orange decline. Influence of current and previous agricultural inputs prices on tangerine is smaller than orange; Current RMB appreciation led to NSP of tangerine and orange decline and precious RMB appreciation led to NSP of tangerine and orange rise.Influence of current and previous RMB appreciation on NSP of tangerine is slightly smaller than orange.This article analyses and makes comprehensive survey on the direction and degree of impact of agricultural inputs prices and the RMB exchange rate on international competitiveness of citrus with different scale and different mode of operation by building panel data model and adopting the combing method of vertical comparison and lateral comparison.The results show that increasing of agricultural inputs prices and RMB appreciation have negative impacts on potential competitiveness of citrus with different scales and different modes of operation in China main citrus producing ares. Under the same cultivation condition, negative impact of agricultural inputs prices increase and RMB appreciation on potential competitiveness of citrus with professional management on larger-scale is smaller than smaller-scale’s, negative impact of agricultural inputs prices increase and RMB appreciation on potential competitiveness of citrus with concurrent business operating on larger-scale is larger than smaller-scale’s. Under the condition of the same scale, the negative impact of inputs prices increase and RMB appreciation on potential competitiveness of citrus with professional management is smaller than concurrent business operating.Under the conditions of agricultural land System at this stage, large-scale professional management for citrus is moderate scale operation mode in main citrus producing areas.Based on the conclusions of empirical study from Chapter four to Chapter eight, there are five measures and policies to be recommended:to optimize resource allocation of agricultural inputs and improve input-output efficiency of citrus; to improve the long regulation of control agricultural inputs prices and keep citrus production costs relatively stable; to promote the transformation of the development mode of the citrus industry and strengthen competitiveness of citrus; to look for international and domestic markets and improve structure of the varieties and quality of the citrus; to improve the relevant policies and regulations and create institutional environment which enhance the international competitiveness of the citrus.This article will makes innovative exploration on the basis of previous studies:Firstly, from the eview of input and competitiveness,this article study the direction and degree of impact of price of chemical fertilizer,pesticides,labor and the RMB exchange rate on international competitiveness of citrus overall and the citrus of various varieties through multiple linear regression model for the first time. This method of quantitative analysis intuitively verify the causal relationship of impact of the former on the later, measures the degree of association between the two.The study make up for the lack of research in the field of agriculture and the international competitiveness of agricultural products.Secondly, it the first time for this article to choose agricultural input prices and the RMB exchange rate as explanatory variables and planting and management regulatory with varied dummy variables to build a variable coefficients fixed effects panel data model to investigate the direction,degree and difference of influence of agricultural input prices and the RMB exchange rate on international competitiveness of citrus with different scale and different mode of operation.This study may perfect research in the field of agriculture and the international competitiveness of agricultural products.Thirdly, this article analyses direction and degree of impact of agricultural inputs prices and the RMB exchange rate on dominant or potential competitiveness of citrus as a whole and of different types and with different scale and different mode of operation by comprehensive comparison analysis which combining multi-level horizontal comparison with longitudinal comparisons for the first time. At last,it draws a complete and exact conclusion.This multifaceted dimension comparative analysis may provides a new idea for in-depth study international competitiveness of other horticultural products or agricultural products.
