This study examines the role of technological innovation and economic progress on environmental pollution by using STRIPAT and EKC theoretical frameworks in 25 developing Asian countries from the period 1998 to 2019. For technological advancement, the energy intensity has been used to gauge how much of the quantity of energy is employed to produce the additional unit of gross domestic product at domestic level. Therefore, the volume of the energy used in the production process is highly important as it is documented through the energy intensity. To capture the impact of innovation, the sum of total patent applications and trademark applications for the sampled countries has been used. This study applied second-generation unit root and panel cointegration techniques to estimate the results. To estimate the long-run relationship of variables and the cross-sectional interdependence, Pedroni Residual and Westerlund Cointegration tests are applied. Further, the Hausman-Taylor-type test has been used to check the efficiency of the pool mean group (PMG). The results of PMG regression confirm the existence of EKC in the developing Asian countries. The results of this study showed that technological development, innovations, and economic progress have the potential to reduce carbon emission and to protect the environment in developing Asian economies. Moreover, the results of error correction model indicate that in case of any external shock, this model will converge towards equilibrium within 64.6 years. The study proposed that a policy framework related to technological innovations should be sustained and the advancement of human capital and research and development should be the primary focus of the developing nations to mitigate the environmental challenges.
本研究使用 STRIPAT 和 EKC 理论框架，在 1998 年至 2019 年期间，考察了技术创新和经济进步对环境污染的影响。在技术进步方面，使用能源强度来衡量国内生产总值每增加一个单位所消耗的能源数量。因此，生产过程中能源的使用量非常重要，因为它通过能源强度来记录。为了捕捉创新的影响，使用了样本国家的总专利申请和商标申请的总和。本研究应用了第二代单位根和面板协整技术来估计结果。为了估计变量的长期关系和横截面相互依存关系，应用了 Pedroni 残差和 Westerlund 协整检验。此外，还使用豪斯曼-泰勒检验检查了平均组（PMG）的效率。PMG 回归的结果证实了发展中亚洲国家存在 EKC。本研究的结果表明，技术发展、创新和经济进步有可能减少碳排放，保护发展中亚洲经济体的环境。此外，误差修正模型的结果表明，如果发生任何外部冲击，该模型将在 64.6 年内收敛到均衡。该研究提出，应该维持与技术创新相关的政策框架，发展中国家应该将人力资本和研发的提升作为首要重点，以减轻环境挑战。
