Agriculture is the basic industry of the national economy, and the transformation of agricultural economic growth mode is of great significance to ensure the supply of agricultural products and improve the quality of agricultural products. Therefore, it is the only way to solve this problem to change the way of agricultural economic growth through scientific and technological investment, industrial structure adjustment, and other methods. Based on the fuzzy comprehensive evaluation method, this paper analyzes various factors of agricultural economic development and establishes a multilevel fuzzy comprehensive evaluation model of the development status of agricultural economic system. The stochastic frontier production function model of the fuzzy control comprehensive model is applied to decompose the agricultural labor productivity, and the counterfactual thinking and distribution method are used to analyze the influence of these factors on the evolution of provincial agricultural labor productivity differences. The value inequality decomposition method measures the contribution of each factor to the provincial agricultural labor productivity difference as well as the contribution of exogenous explanatory variables to the provincial agricultural technical efficiency difference. It is concluded that the relative contribution rate of nonagricultural activities to the difference in agricultural technical efficiency is the largest, and the average relative contribution rate reaches 74%. The improvement of agricultural labor productivity cannot rely solely on the increase in the input of agricultural material factors, but should rely on science and technology.

ABSTRACT:Tremendous impact e-commerce development to human society makes a series of research in related fields to become a global hot spots. In recent years, the development of e-commerce has gradually slowed down, which is one of the main security problems that hinder its development. It can be predicted to be into the true meaning of e-commerce era, security must be addressed. This paper argues that the security of e-commerce is based on trust, the sole factor in consumer confidence in e-commerce security, not hinder, the law is to protect the security of e-commerce and trust, and make some recommended measures to enhance user confidence in e-commerce transactions, thus promoting e-commerce fast! healthy development.
