Eliminating poverty, improving people’s livelihood and gradually realizing common prosperity are the essential requirements of the socialism (Wang, 2016; Zhuang et al., 2016; He, 2017) . Since the reform and opening up, China’s governments at all levels have focused on poverty alleviation and poverty shaking off. And the poverty alleviation policy has shifted and there are different forms, such as reform to promote poverty alleviation, rural development poverty alleviation and development and protection combination poverty alleviation. In recent years, China pursues all-round precision poverty alleviation; in addition to targeting all the poor population, the precise principle runs through the whole process of poverty alleviation (Luo & Yi, 2011; Ma & Kai, 2017; Gong & Gong, 2017; Huang, 2016; Tan & Lin, 2017) . Different from the foreign countries taking payments to support the poor, China adopts the strategy of multiple paths in poverty alleviation and the development of production poverty alleviation as the main path after aiming at the poor population (Zhang et al., 2015) , and industry poverty alleviation has become the most important way to precision poverty alleviation (Huang et al., 2017) .
At the same time, the academic circles summarize the rich experience of precise poverty alleviation in the areas of mountain (Ma, 2016; Li, 2017; Sun, 2016) , ethnic minority areas (Liu et al., 2017; Yu, 2016; Yang, 2016; Yu, 2016) , concentrated contiguous poverty-stricken areas (Yang, 2016) , and other different types of areas in the country, and study the plight and solution measures of precision poverty alleviation in specific industries in specific areas (Huang et al., 2017; Ma, 2016; Yang, 2016) . They studied in the theoretical orientation (Liu & Zhan, 2016) , function mechanism (Chen, 2016) , path selection (Sun, 2016; Chen, 2016) , implementation method (Li, 2013) , policy simulation (Chen, 2016) , policy evolution (Wang, Li, & Zuo, 2016) , policy differentiation and other aspects of the industry precise poverty alleviation, and put forward a series of unique insights (Yu, 2016) , and discussed the relationship between the environmental protection and industry precision poverty alleviation (Han, Sun, & Pu, 2009) , supply side structural reform and precision poverty alleviation (Kong, Zheng, & Liu, 2017) , the application of big data in industry precision poverty alleviation (Zheng & Cao, 2015) , and other aspects of the precise poverty alleviation. The research of the specific industries in poverty alleviation has been done, such as the important role of industrious in the precise poverty alleviation (Wang & Yu, 2017) , characteristic industries in the precise poverty alleviation (Zhang & Dou, 2017) , the relationships in characteristic industry (Geng, 2017) and the coupling relationship between financial services and characteristic industry in the precise poverty alleviation.
The above research has made a positive contribution to industrial precision poverty alleviation. However, in the background of precise poverty alleviation, how to develop the regional characteristic industry to give full play to the poverty alleviation effect deserves further study. Based on the analysis of poverty characteristics in Danfeng County, this paper discusses the development strategies of walnut industry in the county, in order to enrich the theory of characteristic industry precise poverty alleviation and guide the practice of precise poverty alleviation.
2. The Characteristics of Poverty in Danfeng County

3. The Role of Walnut Industry in Presice Poverty Alleviation in Danfeng
Industrial poverty alleviation is one of the important ways to alleviate poverty. The development prospect of walnut industry and the competitive advantage of walnut in Danfeng County make the industry play an important role in the precise poverty alleviation in Danfeng County.
3.1. The Walnut Industry in Danfeng County Has a Promising Prospect
Walnut contain many kinds of nutritious ingredients beneficial to human body, which are good for human health (Li et al., 2009; Yang et al., 2017) . The demand for walnuts in international markets is growing fast. According to the latest statistics from the UN food and agriculture organization, the total trade volume of walnut and walnut meat in the world was 551,367 tons and 350,355 tons respectively in 2013. Trade volume increased by 2.71 times and 1.97 times compared with 2003. The United Nations food and agriculture organization predicts that the annual growth rate of international walnut demand will remain above 10 percent for the next 10 years.
Asian and Chinese walnut imports are rising fast.

With the improvement of people’s living standard and health care consciousness enhancement, walnut products in the international market demand and volume increased year by year, a huge number of population product consumption and demand for walnuts in China will grow rapidly and walnut industry has great development prospects.
3.2. The Walnut Industry in Danfeng County Has Obvious Competitive Advantage
Planting history and planting preferences. Danfeng County is known as the walnut capital of China. The walnut cultivation in Danfeng County can be traced back to the han dynasty. It was the first place in China that successfully introduced the walnut. The book in qianlong period of the qing dynasty named Zhili Shangzhou wrote: the most delicious food in Shangluo state is the walnut. There are 1900 walnut trees in wuguan township of danfeng County, with an annual output of 2000 kilograms, before liberation in 1949. After the founding of new China, the planting of walnuts was more common, and its planting experience has been promoted to the whole country many times.
Walnut regional brand. In 1958, chairman MAO Ze-dong introduced the experience to the whole country, and the experience was to grow an acre of walnuts per acre in Shangluo district. In the same year, chairman MAO Ze-dong held a production of walnut production at Bayi Forest Farm in Wuguan Town, Danfeng County, and awarded the state council certificate signed by premier Zhou En-lai to Bayi Forest Farm in Wuguan Town. In 2008, danfeng walnuts became a national geographic brand, and wuguan walnuts gained national geographic sign registration protection. Chairman MAO’s call and premier zhou’s signing of the award, for the danfengxian county walnut regional brand to add luster. The establishment of the protection brand of geographical indications makes the chicken walnut truly become the important agricultural product regional brand in China.
Location advantage. Dan-feng County is located in the south of the eastern section of Qin-ling Mountains, and the elevation is between 500 and 1200 m. The terrain is dominated by the valley and mountainous terrain, and the mountain peaks are separated and undulating. Because of the barrier of the Qin-ling Mountains, the climate is mild, the winter is not very cold, the summer is not very hot, the rain is abundant, the four seasons are clear, it is the natural ideal growth place of walnut. China is a big importer of walnuts. In recent years, more than 64,000 tons of raw walnut and walnut meat have been imported from abroad, and the demand and imports are still growing at a high speed. In this context, the location advantage of the walnut industry is very obvious. First, compared with the pecan producing areas, the location advantage of the walnuts has been converted into cost advantage. Dan-feng County is located in the eastern part of the Qin-ling Mountains, and the Shang-yu Ancient Road through the county. The G312 National Highway and the Xihe Railway Line runs diagonally across the county, providing convenient transportation for walnut products to be shipped to the country. Second, compared with the domestic walnut producing region, the development of the walnut industry has obvious scale advantages. All over the Shang-luo District includes Dan-feng County is a brand of walnuts, with good quality and high yield. With an annual production capacity of 20,000 tons, walnut production ranks first in the national prefecture-level cities. The scale advantages effect of Dan-feng walnut was obviously, the development potential of walnut industry is huge, which is in competition with walnut products in other parts of the country. Third, the related industries of the Dan-feng walnut industry are well matched, which can effectively reduce the cost of sales. There is rich tourism resource in Danfeng County, which can form a coordinated development between the tourism industry and the walnut industry.

In walnut planting, the mountainous terrain and broken block is small, so the walnut field of digging, Weeding fertilization, pest fruit picking, etc. to mechanical work, must be manually operated, so more labor cost. The pruning of walnut branch needs certain experience, also must manual work, need to spend more labor force. Walnut pretreating, bigger and complete walnuts the highest prices, the price of the first-class is often twice of the seconds. Therefore, walnuts are usually used in the processing of walnut food by manual shell, can absorb more common labor. Similarly, the transport of walnuts and its products, as well as the production of walnut food and walnut oil, also absorbs more general labor.
3.4. The Walnut Industry in Danfeng County Can Increase the Farmers Income
Investigation shows, the walnut yield of Danfeng County between 3000 - 4500 kg/hm2, the walnut purchase price for 10 - 15 yuan/kg, the cost of fertilize about 3000 yuan/hm2・a, and the cost of pesticide about 600 yuan/hm2・a, the land transfer costs 12,000 yuan/hm2・a. In normal years, the walnut purchase price was 10 yuan/kg with the walnut yield 3000 kg/hm2, and the profit is 14,400 yuan/hm2・a. According to the local terrain conditions and mechanization level, a labor force usually can grow 0.75 hectares of walnuts. Under the background of land transfer, the annual income of a labor force planted walnut can reach 10,800 yuan, which can drive 3 people out of poverty. The development of walnut industry can bring some profit for farmers. The walnut hand shelling as an example, a farmer can peel walnut 15 kilograms every day, if the according to 2 yuan/kg, each labor can earn 900 yuan a month. If the time can be arranged scientifically, each labor works 3 months a year, and can earn 2700 yuan per year. If we consider the walnut deep processing and walnut industry to promote the development of tourism and increase farmers’ employment opportunities and increase farmers’ income, the effect of increasing farmers’ income of walnut industry development will be more obvious.
