Now consumption of main food in Taiwan of China has been stable. It is most likely that Chinese Mainland will follow the progressive path of food consumption in Taiwan of China. The total dietary consumption of Chinese Mainland residents will reach the summit around 2026, so will the consumption of food with high added values, such as fruit, meat, egg, aquatic products, dairy products, and oil. Total dietary consumption will be 563 kg per capita, and grain consumption will be 456 kg per capita. The structure of dietary consumption will reach a table state by 2035, and total dietary consumption and grain consumption will be 499 kg per capita and 412 kg per capita, respectively. Dietary consumption of Chinese Mainland residents has great potentials for promotion, which will exert long and continuous pressure on China’s limited land and water resources.

According to the features of using process, the energy use could be divided into two categories including the energy use in the field of consumption (EUFC) to provide services and the energy using in the field of production (EUFP) to provide products. The feature of EUFC is different with EUFP, including evaluation methods, energy saving approach and developing strategy, etc. Considering its potential to be the main growing sector in the next period of energy consumption, more attention should be paid to EUFC. In this paper, based on the analysis of its features, the measure of EUFC and the energy saving approach are recommended, as well as the suggestions to the present situation in China.

Energy is the foundation of human activities and has driven the evolution of human civilization and social development. Although fossil fuel causes great progress in industrial civilization worldwide, its consumption also brings negative effects, e.g., environmental pollution, global climate change, energy poverty, and energy safety. In the meantime, the fast growing on high-carbon energy and total energy consumption in China has become one of the primary causes of the ecological unbalance and continues domestic environmental deterioration such as air pollution, water pollution and soil pollution, etc. The key to solving the current environmental and climate problems is to promote energy revolution and realize a green life-cycle process of energy production, transmission, consumption. Pushing forward the construction of ecological civilization will also be the basic factor. This paper reviews the history of human culture and energy evolution. It analyzes the trend of global energy evolution and puts forward suggestions to promote energy revolution under the background of construction of ecological civilization.

At the end of the 20th century Ministry of Agriculture of China put forward a strategic principle for agricultural development the main contents of which are paying equal attention to cereals crops, economic crops and feed crops. It stressed the importance of combination of agriculture and animal husbandry.
National dietary structure has had a great change in the past 20 years in China. It shows that the increasing quantity of meat, eggs and milk has been easing off the shortage of cereals. It´s estimated that there will be a shortage of 50% of protein for feed in the mid-long term for China to reache the leading level of the average per capita animal protein in the developing countries, especially the shortage of main limiting-amino acids, such as lysine and methionine, will be more critical. Considering the national conditions and strength, it is difficult to produce amino acids through the industrial way owing to the limitation of the investment, technique and ingredients. It is an effective way to solve the shortage of protein for feed that the internal quality of the agricultural production should be reformed and the increasing of quantity and the raising of quality of the protein for feed should rely on planting agriculture. There were many successful experiences in reforming the quality of the protein for feedstuffs. For example, high-lysine corn, low-glucosinolate rape seed and glandless cotton seed, etc. For this purpose, the internal timprovement of the agricultural production is not only to solve the shortage of the protein for feed, but also to be a strategic behave for improving the f

Carbohydrates, which are mostly present in sugar, starch, and fiber, are one of the main ingredients of food and the primary source of energy in the human diet. Among these three main sources, starch stands out as one of the most abundant reserves of carbohydrates. Investigating starch would not only enhance our understanding of the functionality of starch in the human body but also aid in the design of novel starch-based dietary foods. The present review first provides a state-of-the-art understanding of the various classifications of dietary starches, including rapidly digesting starch (RDS), slowly digesting starch (SDS), and resistant starch (RS). Moreover, both the in vivo and in vitro determination methods of the digestibility of starch-based dietary foods are discussed. Based on the current understanding, present research strategies to design novel starch-based dietary foods through either the direct addition of modified starch or the alteration of processing conditions are highlighted. Furthermore, certain perspectives related to the future research directions of starch-based foods are also included.

Diets significantly affect the nutrition and health of people as well as the resources and environment. Promoting a sustainable healthy diets among the Chinese population is crucial for implementing the Healthy China initiative, fostering sustainable development, and ensuring national food security in China. This study reviews the forming process of the sustainable healthy diets concept, presents several representative sustainable dietary patterns, and clarifies the international consensus on sustainable healthy diets from the perspectives of nutrition and health, resource and environment, and socio-economics. Moreover, it analyzes the current dietary patterns of Chinese residents and focuses on associated nutrition and health issues and resource and environmental challenges caused by changes in dietary patterns. Furthermore, we recommend that China should propose targeted plans to guide and optimize residents' dietary patterns, implement multiple measures to foster a healthy and sustainable food consumption habit among residents, and establish a sustainable and healthy dietary supply system. This can help cope with the double challenges of increasing nutritional imbalance and environmental degradation and improve the formulation of national food policies.

With access to information is becoming more and more convenient and quick， the strategic behavior of customers is becoming more common in everyday life. In this paper， we study the optimal pricing of perishable goods in the presence of strategic customers. Monopolist sells a finite quantify of products in a certain period of time. Customers select the optimal time to buy based on the principle of utility maximization. This paper is divided into two scenarios including not replenish inventory and replenish inventory. Studies have shown that the game equilibrium exists between sellers and consumers. After a seller announces the pricing strategy， the structure of customers is divided by an optimal threshold function. The strategic behavior of customers has a significant impact on the profits of a seller. A seller can accord to the market demand and the time sensitivity of customers through proper inventory and price setting to reduce losses from the strategic behavior of customers. The situation with replenishing inventory is better than the situation without replenishing inventory only when market demand is larger.

In this paper，taking an annual output of 1×109 m3 coal to substitute natural gas(SNG) as an example，Shell coal gasification technology was used to produce synthesis gas. The equipment investment of air separation system（ASU），water gas shift system（WGS），wind power plant（WP） and electrolyzed water system（EWS） was compared between traditional coal-to-SNG and wind/coal SNG. The oxygen consumption，water steam consumption，electricity consumption and CO2 emission were also analyzed. Results show that although the investment of WP and EWS replacing the ASU and WGS is huge， its average annual operating cost（equipment investment，raw materials，power consumption） is lower，and CO2 emission is only 1.3 % of the traditional coal-to-SNG technology. This paper provides a reference for the development of coal-to-SNG industry.

Conducting supply-demand prediction and structural adjustment of planting and breeding industries based on changes in food consumption is crucial for ensuring food security of China. This study analyzes the characteristics of food consumption structure and the development trends of planting and breeding industries in China and estimates the demand and supply data of staple grains, feed grains, and forage crops closely related to the planting and breeding industries. The analysis results of supplydemand balance are obtained. Targeted adjustment directions are proposed, including expanding the planting of protein feed crops, oil-bearing crops, and high-quality forage crops; stabilizing the production of livestock and poultry; vigorously developing grassbased animal husbandry; promoting an all-encompassing approach to food; and exploring multiple sources of food. The study also elaborates on the implementation paths: optimizing planting structure by adjusting regional layout, developing circular agriculture that integrates crop farming and animal husbandry, constructing a diversified food supply system, and comprehensively enhancing innovation capabilities regarding agricultural technologies. To better ensure national food security, we proposes to improve the policy and technological support systems, allocate agricultural resources toward roduction areas, establish a regional collaboration mechanism, and adjust policies and statistical standards for staple grain, feed grain, and forage crop production.

Northwest China is rich in energy resources. However, problems such as low energy efficiency and energy structure mismatch remain. Assessing the energy development level and designing energy development paths are crucial for ensuring energy security and promoting energy development quality in Northwest China. This study analyzed the characteristics of energy production and consumption in Northwest China and clarified the prominent problems in energy development. The gray forecasting and multiple regression methods were used to forecast the energy development level from 2023 to 2030, and the energy development path in Northwest China was designed accordingly. Our results show that in Northwest China, the energy structure has been continuously optimized in recent years, and the production and consumption of renewable energies continued to rise; however, the production and consumption of renewable energies was still far lower than that of traditional energies. In addition, the impact of economic, industrial,and technological issues on energy development is significant. To promote the green renewal and development through energy transition, this study proposed to focus on the integration of traditional and new energies, adopt development methods such as supply revolution, consumption revolution, technological revolution, institutional revolution, exchange and cooperation, and implement an energy development action plan using a multi-subject collaborative approach.

Strategic Study of CAE 2000, Volume 2, Issue 6, Pages 52-58
The energy consumption in rural area of China is related to the activities of agricultural econome, living standard and environmental quality. The paper analyses mainly the energy consumption conditions in the rural area. The total energy consumption (converted to coal equivalent, the same below) in rural area reached to 690 Mt in 1995, including 325 Mt consumed by township enterprises. But the annual per capita commodity energy consumpsion was only 0.56 t, far below the national average. The energy consumption of township enterprises increased rapidly in the past 17 years and reached 325 Mt in 1995, which was 65 % of the total commodity energy consumed in rural area.
By the efforts of rural energy development, about 30 Mt is obtained from renewable energy utilization of small scale hydropower, biogas, solar and wind energy etc. . The rural energy development increased effectively the energy supply to rural area, improved the structure of rural energy consumption, and promoted the rural social economy development. The population of lack firewood was reduced from 420 millions in 1979 to 70 millions in 1995. Along with raising of living level in rural area, the demand of high quality fuel increases year by year. There were 48 million of households used different high quality energies such as gases and LPG etc. in 1995. This paper analyses objectively the existing proplems related to energy, social and environment, etc. . It is the foundation of further discussion on the stratagem of rural energy development.
