“…The land is the main carrier of agricultural planting, so the scale of agricultural arable land is a direct factor re ecting the level of agricultural development. However, China's agricultural arable land has dropped from 1.95 billion mu (130,000 square kilometers) in 1996 to 1.87 billion mu (124,666.67 square kilometers) in 2020, and the area of agricultural arable land is constantly approaching the red line of China's agricultural arable land area [21]. Second, agricultural water resource quantity and quality both drop.…”

This work aims to promote the concept of green development of agriculture and the sustainable development of China’s agriculture. First, the application concept of digital technology is expounded. Then, the basic idea of the fuzzy system is discussed. Finally, the composition and development of China’s green agricultural total factor productivity (ATFP) are analyzed, and the green ATFP model is constructed. The results demonstrate that the current agricultural development mainly depends on labor force and resources, and the transformation of labor force structure is an essential factor affecting the agricultural development. The agricultural labor force especially changes to feminization, aging, and urbanization, resulting in a severe shortage of agricultural labor force and retardation in agricultural development. In addition, this work builds the theoretical framework of green ATFP based on the guidance of digital technology and fuzzy system. The evaluation results indicate that the contribution rate of each index drops significantly under the green ATFP model, and the highest contribution rate is around 1.23. It can be seen that the current measures of China’s green agricultural total elements are not perfect, the development of China’s agriculture is not sufficient, and the emphasis on the environment is not high enough. The research reported here provides a reference for promoting the development of agriculture and contributes to the green development of agriculture in China.

“…However, most of the time, it is well-known that the insurance industry is a pro-cyclical market, so it takes a lot of risks to build up a separate portfolio of insurance companies. According to Liu, G. and Molise, T, countercyclical capital is an effective buffer against the pro-cyclical nature of its predecessor [7]. To solve this problem, some counter-cyclical industries need to be considered to reduce risk, and here I've chosen three typical agri-tech companies.…”

I look at how investors can use insurance market stocks to make a profit and reduce risk by increasing their investments in high-tech agricultural types of counter-cyclical industries. By comparing the correlation coefficient between the two companies, the investment target is determined, and then the scatter diagram is drawn to observe the distribution of the random portfolio. Then，the optimal portfolio is obtained by studying the efficient boundary on the scatter diagram and the Sharpe ratio in various special cases. Through these analyses, I found that the portfolio on the effective frontier is the maximum return at the corresponding risk or the minimum risk at the corresponding return. Moreover, investors can determine the best portfolio by calculating the maximum Sharpe ratio, and the portfolio corresponding to the maximum Sharpe ratio is also on the efficient frontier. This research has great significance in real life. It can let people not limited to the pure investment insurance business, but try to hold insurance company shares for a long period to get profit.
