RESUMO
The analysis of food consumption pattern is a primary concern of any developing country because it is related with food security. Pakistan is one of the emerging nations of the developing world. Due to the similarities and differences in households' food consumption behavior, income distribution, the effects of alternative tax structures, cost-benefit analyses, and the choice of cost of living index, the study of households' food consumption pattern is crucial for a developing nation like Pakistan. Furthermore, for Pakistan's food security in the present and the future, an analysis of food consumption pattern is crucial. The main objective of this study is to analyze the households' food consumption pattern. Linear Approximation Almost Ideal Demand System (LA/AIDS) is applied using data from Household Integrated Economic Survey (HIES) for the year 2018-19. This study makes a significant contribution by estimating household age composition elasticities, which were absent from earlier studies. Results from the income elasticities reveal that milk, meat, and fruits are luxuries food items. Similarly, on the basis of inelastic income elasticities we declared cereals, pulses, vegetables, sugar, and ghee as necessity food items. Results from the compensated own price elasticities show that the eight food commodity groups have inelastic own-price elasticities. This implies that these food commodities are integral food items of household diet. Results from the compensated cross-price elasticities shows that cereals and pulses, cereals and vegetables, pulses and vegetables, milk and fruits, meat and fruits, and milk and ghee are gross substitutes. On the other hand, pulses and meat, pulses and fruits, and ghee and meat are gross complements. According to the findings of the household age composition elasticities, adding children to a household significantly increases its sugar consumption while significantly reducing its fruit consumption. Any increase in the size of the household by an adolescent, adult, or a person in their middle age results in a significant increase in the consumption of cereals and a significant drop in the consumption of fruits. Finally, any increase in the size of the households brought about by an elder resulted in a significant rise in the consumption of cereals and a significant drop in the consumption of vegetables.
RESUMO
The industrial sector of China is critical to the country's economic growth. On the other side, industrialisation has resulted in a high rate of emissions, pushing China to spend extensively on industrial pollution remediation. As a result, this study looks at the relationship between investment completed in the treatment of industrial pollution and economic development. Initially, the study used the global Moran's I test (Queen's contiguity matrix) to find spatial autocorrelation for the 'investment completed in the treatment of industrial pollution' factor, where the study found a positive association across Chinese provinces, and suggest the existence of spatial autocorrelation. Thereafter, a time-fixed effect spatial error model was used due to the lowest Akaike information criterion and Bayesian information criterion to analyse regional data of China from 1999 to 2018. The data reveal a positive association between investment completed in the treatment of industrial pollution and regional economic growth, both in the short and long term. Furthermore, the negative consequences of urban wages and foreign investment on investment completed in the treatment of industrial pollution are having the reverse effect on regional green development, necessitating ecologically friendly actions to mitigate the negative environmental effects of both. The results highlight the need for policymakers in other countries to review their plans for economic expansion and create environmentally friendly legislation. By implementing the Chinese green economic growth model, policymakers in industrially polluting nations can reduce industrial pollution and foster green growth in their nation.
