我国水稻种植机械化高产技术发展

随着我国科技水平的不断提高,农业机械化生产成为未来的发展趋势。而我国水稻种植的特点也决定了它的种植机械化程度,所以要促进我国水稻种植机械化高产技术的发展,就需要了解我国水稻种植的特点,并且要针对当前我国水稻种植机械化过程中存在的问题,提出切实可行的解决措施。

China’s Imports Technology Structure and Its Relationship with Trade Partners:1995-2011

This paper uses the latest data to analyze the historical patterns and the current situation of the technology structure of China＇ commodities imports, the structure of China＇s commodities imports from 19 countries and regions, and China＇s interdependent relationship with its trade partners on the basis of studying 230 kinds of manufactured products categorized by their technological intensity. The results show that during the period of 1995-2011, the share of low technology （low-tech） products and medium technology （medium-tech） products declined,＂ the share of primary products, resource- based products, and high technology （high-tech） products increased; high-tech products had taken the largest share, bypassing low-tech and medium-tech products, as early as 2000; different types of countries exported different kinds of commodities to China and had different positions in China＇s imports; China had relatively high interdependent relations with Japan, South Korea and China＇s Taiwan; China had relatively low interdependent relations with the United States, Germany, France and the Netherlands; China＇s import dependence on major developing countries and emerging developing countries was less than these countries＇ export dependence on China; China was the leading export destination for major developing countries and emerging developing countries. Generally speaking, the development of China＇s import trade is inclusive, and China shares its growth with other countries. It not only promotes developing countries＇exports but also enhances developed countries＇ exports.

Optimization and competition promotion of industrial structure in Blue Shandong Peninsula Economic Zone

Blue economic zone is a typical regional economic mode,which is specially characterized by marine economy and has multiple economic types coexisting and interacting through integrating marine and land resources.With the continuous progress of science and technology,marine economy as a strategy to promote economic development is approved in many countries.The Blue Shandong Peninsula Economic Zone(BSPEZ) reflects the local demands of economic development,and its upgrading and enhancing competitiveness of the industrial structure is also of obvious significance for enhancement of the development of eastern China and the national marine economy.This paper thinks that the BSPEZ has many advantages,such as unique marine economy,growing high-tech industries,more and more mature industrial system,advancing technological innovation,and outstanding big enterprises,large projects and regional bright brands,but it is also facing problems of low industry cluster,similar industrial structure with each other,still weak technological innovation.So we put forwards the basic approaches to upgrade and enhance the industrial structure:transforming and upgrading the traditional marine industries with advantages,accelerating the development of new marine industries and high-tech industries,integrating marine and land industry,and promoting the rational system arrangements.

Generative Artificial Intelligence Technology Driving High-quality Development of Ice and Snow Tourism Industry:Factor Linkage,System Construction and Digital Governance

Generative Artificial Intelligence technology embedded brings new opportunities and challenges for thehigh-quality development of ice and snow tourism industry.Using literature and other research methods,we constructed the element linkage and system of generative AI technology to drive the high-quality development of theice and snow tourism industry and proposed the digital governance path.The results showed that:(1)The factorlinkage of high-quality development of ice and snow tourism industry with integrated basic structure and coupledcentral system of multi-factor linkage;multi-directional strategic objectives and synergistic triple benefits;and intelligent operation logic and precise matching of supply and demand has been constructed.(2)Based on the synergyof digital governance elements,a five-factor synergistic development system was built with digital talent elements,technological innovation elements,product innovation elements,data resource elements and channel innovationelements.(3)The synergy of elements provided digital governance path guidelines for the high-quality developmentof ice and snow tourism industry,digital governance system:precise supply of policies and regulations,andstrengthening of soft and hard constraints to promote;digital governance structure:building a three-dimensionalregulatory mechanism,and advancing the governance process of targeting;digital governance subject:driving thetwo-way reach of the governance subject,and strengthening the common governance of pluralistic subjects;digitalgovernance capacity:precise allocation of governance resources,and driving the transformation and upgrading ofelemental endowments.The results of this research can help to provide ideas and reference for the high-qualitydevelopment of ice and snow tourism industry empowered by Generative Artificial Intelligence technology andimprove the theoretical research on the high-quality development of ice and snow tourism industry.
