The second is an important way to build a new countryside and a harmonious countryside. The core of new rural construction is to develop production and affluent life, develop rural secondary and tertiary industries with emphasis on agricultural product processing industry, and transform the advantages of agricultural and rural resources into economic advantages, thus forming a new situation in which industrialization promotes agriculture, industrialized affluent farmers and urbanization drives rural and urban-rural harmonious development; The third is the core link of modern agriculture. Modern agriculture consists of three systems: modern breeding industry, modern agricultural product processing industry and modern agricultural product logistics industry, and agricultural product processing industry is in a decisive position. Driven by the processing industry, we will extend the agricultural industrial chain, value chain, interest chain and employment chain, promote agricultural specialization, scale, standardization and marketization, open up the primary, secondary and tertiary industries, and drive a series of related industries; Fourth, it is an important means to promote farmers' employment and income increase. According to estimates, every 0. 1 percentage point increase in the proportion of agricultural products processing in agriculture will drive 2.3 million people to find jobs and increase the per capita income of farmers 193 yuan. Fifth, it is an important guarantee to improve the quality of life of urban and rural residents. China's per capita GDP has exceeded US$ 65,438 +0.700 yuan, and the new characteristics such as diversification, convenience, nutrition, safety and personalization of diet and life demand require the agricultural product processing industry to adapt to it and play the role of guiding and stimulating consumption.
In recent years, China's agricultural product processing industry has made great progress. According to the development plan of agricultural products processing industry during the Eleventh Five-Year Plan period, by 20 10, the conversion rate of major agricultural products (above primary processing) in China will reach 60%, and the proportion of deep processing will increase obviously, and the proportion of deep processing of major agricultural products (products processed more than twice will account for more than 40% of its output).
Corresponding to the above objectives and tasks, the plan also proposes that by 20 10, the localization rate of key equipment for agricultural products processing in China should reach over 60%, the overall level of technical equipment should reach the international advanced level at the beginning of 2 1 century, and some areas should reach the international advanced level at the same time. During the Tenth Five-Year Plan period, the research and development level of agricultural products processing equipment in China has steadily improved, but the technological innovation ability of agricultural products processing equipment has become a decisive factor in the competitiveness of agricultural products processing equipment in the world. Therefore, in order to achieve the above goals, technological innovation should be regarded as an important means to realize the technological leap of agricultural products processing equipment.
