“…Econometric methods have been applied to investigate the spillover effect of technology diffusion. Spatial autocorrelation coefficients, like the Moran index, have often been used for impact evaluation (Mamiit et al, 2020;Zhang et al, 2021). Based on this index, the interrelationship of technological innovation among regions can be displayed vividly on geographical maps.…”

The widespread adoption of hybrid rice varieties in China is a successful example, showing the role of agricultural technology in terms of food security. However, the dynamic diffusion of hybrid rice varieties and their effect on rice production requires further study. Based on data on hybrid rice adoption at the provincial level from 1984 to 2011, we applied the Ordinary Least Squares (OLS) and Geographically and Temporally Weighted Regression (GTWR) models to investigate the spatial and temporal effects of hybrid rice adoption at national and provincial levels. Overall, the effects of hybrid rice adoption on rice production have decreased over time. However, the results showed possible spillover and crowding effects of hybrid rice adoption across provinces. In particular, the development of hybrid rice varieties in Hunan province has had a significant influence on changes in rice yield and the distribution of rice areas in other regions. This study, therefore, serves as a reference in understanding the dynamic distribution of high-yield rice variety adoption in relation to food security and for designing appropriate agricultural extension strategies. However, further research is needed to identify the determinants affecting changes in rice farming in complex environments and associated ecological systems.

“…To determine the specific study sites, we followed the approach that Mamiit et al (2020) employed by considering the rice harvest areas at the provincial, municipal, and village levels. With the approach, we selected the municipalities of Guimba in Nueva Ecija and Tarlac City in Tarlac.…”

“…In choosing the sample villages, we adopted the right coverage approach described in Mamiit et al (2020). Through random selection, that was contingent on the proportional zonal distribution of the villages as well as the number of rice farming households in the northeast, southeast, southwest, and northwest regions of the two municipalities, we collected information from 471 rice farming households−301 in Guimba and 170 in Tarlac City.…”

“…One technique is the stochastic frontier analysis (SFA), which Aigner et al (1977) and Meeusen and van den Broeck (1977) simultaneously yet independently developed. As described in Mamiit et al (2020), this study also adopted an output-oriented stochastic production frontier model [Eq. (1)] with an exponential distribution assumption following a maximum likelihood framework to estimate technical efficiency.…”

“…Bhanumurthy (2002) further noted that the Cobb-Douglas production function exhibits explicit uniformity, parsimony, and flexibility. As explained in Mamiit et al (2020), this study performed the likelihood-ratio (LR) test as well as the Akaike and Bayesian information criteria (AIC and BIC) to determine that the Cobb-Douglas production function is the most suitable functional form for all the study sites.…”

Rice is the most important staple food in the Philippines as it provides almost half of the calorie requirements of the population. The domestic supply of rice, however, is inadequate to meet local demand, making the Philippines one of the top five rice-importing countries in the world. To close the domestic supply-and-demand gap, agricultural planners and policymakers in the Philippines have been promoting interventions to increase farm-level productivity. In support of the government efforts to increase rice productivity, a stochastic frontier analysis combined with an optimized spatial hot spot analysis was conducted to determine the factors that may influence the increase in rice farm efficiency and also identify candidate areas for relevant geographic-specific rice production interventions. Results show that enhancing access to irrigation and farm inputs and increasing the producers' technical capacity can help address the local supply deficiency by potentially increasing yield per hectare to as high as 5.50 metric tons per hectare. The approach to potentially increase rice farm technical efficiency and productivity must consider the spatial nature of rice production as suggested by the findings from the optimized hot spot analysis. It is important that policy interventions consider areas with a high incidence of low levels of productivity and technical efficiency. These are the locations where agricultural planners and policymakers can make greater impacts on rice yields. Relevant policies and initiatives, therefore, should take into account the geographical location of farms to ensure the greatest contribution to attaining food production targets.
