Study On Comparative Advantage Of The Forestry Industry In China

Forestry is an important part of agriculture; and it has three benefit, they are economic, ecological and social benefits. Forests can not only provide us with all kinds of forest products and wood materials economic benefits, but also it can play a crucial role in nature, such as in water conservation, Wind Protection and Sand Fixation. Besides, forestry's social benefits can be found in absorbing employment, and readjusting industrial structure. The roles of the forestry industry have gained more and more attention; especially in this year, scholars' researches on forestry and forestry industry have become more active.The forestry industry also can be divided into three industries, which are the first industry, the second industry and the third industry. And those three industries have six, seven, and four secondary industries respectively. Due to the influences of natural resource advantages, technology and some other factors, there is imbalance in the development of the forestry industry in 31 provinces of China. Each province has its competitive advantages compared with other members. With the passage of time, and due to the influence of various factors, secondary industries, that have comparative advantages of the internal, may have changed.This paper adopts the forestry production data from 2003 to 2009, which are gotten from the 31 provinces of our country. And eleven secondary industries' production data are selected. After that, we specifically analyze the fluctuant circumstance of provinces' comparative advantages, and study on the changes of eleven secondary industries comparative advantages. At last, we fatherly analyze the changed situation of our country, which are caused by the similarity of forestry industrial comparative advantage with the passage of time. Through a series of calculation and clustering analysis with the help of software spss13.0, we got the following several main conclusions.First, from the transverse perspective, there are 14 provinces that have comparative advantages. Of which the secondary industries comparative advantaged have changed dynamically from the range between 2003 and 2005 to the range between 2007 and 2009. The 14 provinces are Beijing, Jiangsu, Anhui, Jiangxi, Hubei, Guangdong, Guangxi, Chongqing, Zhejiang, Yunnan, Xizang, Gansu, and Xinjiang.And the remains do not change.Second, from the vertical perspective, during the change process from the range between 2003 and 2005 to the range between 2007 and 2009, five maximum location quotient of the 11 selected secondary industries. Second, from the vertical perspective,2003-the first time in 2005 to 2007-the second time in 2009 the change process become bigger; and the other five get smaller. Most of the five Location quotients that get bigger belong to forestry first industry and the third industry, while the secondary industrial locations of the second industry nearly get smaller. Third, clustering results showed that, from the range between 2003 and 2005 to the range between 2007 and 2009, the overall forestry industry structure didn't change dramatically in 31 provinces of our country. During the period of 2003-2005,31 provinces are divided into 5 categories; while during the period of 2007-2009,31 provinces are divided into 4 categories. Two phases of clustering share the same provinces, but there is only one difference that Guangxi province is classed to a type itself, while it is divided into one type with other provinces in the second stage.Fourth, on the whole, the calculated results of the gini coefficient show that the ratio of the gini coefficient of six secondary industries of the first industry is generally small in the first period from 2003 to 2005 and the second period from 2007 to 2009; it means that the dispersivity of the first industry is not big. The gini coefficient of six secondary industries of the first industry varies gently, and even half of the secondary industrial coefficient is negative. It also explains development of the first industry presents balance in 31 provinces. The gini coefficient of four secondary industries of the second industry is larger, and its variation is lager than in the first second industry. Among 31 provinces, the second industry's development is unbalanced. The gini coefficients of the third industry in two periods is not big, and the rate of variation is negative. It shows that all the 31 provinces paid more attention to the development of the third industry, which leads to a relatively balanced development of the third industry.
