Changes in the consumption price of aquatic products will affect demand and fishermen’s income. The accurate prediction of consumer price index provides important information regarding the aquatic product market. Based on the non-linear and non-smooth characteristics of fishery product price series, this paper innovatively proposes a fishery product price forecasting model that is based on Variational Modal Decomposition and improved bald eagle search algorithm optimized Long Short Term Memory Network (VMD-IBES-LSTM). Empirical analysis was conducted using fish price data from the Department of Marketing and Informatization of the Ministry of Agriculture. The proposed model in this study was subsequently compared with common forecasting models such as VMD-LSTM and SSA-LSTM.

Using survey data covering 200 poor households collected between these studies aimed to investigate the role of social security in the fight against. We analyzed the responses behaviours and strategies employed by poor households in response to various forms of risk in depth using questionnaire data. Health, education, housing and income is just a few of the many areas in which social security has an impact. To find out how social security programs affect how families respond to economic shocks, we used a method that looked at both full and partial risk-sharing. According to the estimation results of various models, households that are covered by social security may be able to select less expensive strategies for coping with risks. However, because covered households had less faith in its services and used self-insurance or income smoothing strategies, the role of social security remains inadequate. Overall, the findings demonstrated that social security plays a significant role but that it is still insufficient, particularly for households that are not covered by social security and face high health care costs.
