**1. Introduction**

The secondary information has extensively recognized the key role of infrastructure growth in fascinating FDI inflow. A sound developed infrastructure strategy boosts markets integration and entices FDI inflow in any nation [1], whereas the deficiency of comprehensive infrastructure interrupts markets relationship and herewith slowdown the foreign direct investment (FDI) inflow in particularly developing countries [2]. The obtainability of advanced infrastructure principally decreases the cost of trade, boosts the ease of doing business and invites the foreign direct investment (FDI) inflow. Infrastructure tool is used in this paper as an engine for economic growth and facilitate a comparative advantage to a developing nation in terms of foreign direct investment inflow [3]. Additionally, the secondary data has shown evidence that the nation with good infrastructure engrossed more foreign direct investment inflow [4], whereas the nation's deficient with infrastructure development are stereotypically unsuccessful to attract the FDI inflow [5] and those nation economies also shown that the poor condition [6]. Moreover, it also determined that the impact of the infrastructure development on FDI is positive and significant in a growing economy, preceding research [7] assessed that a deficiency of Infrastructure castigates FDI inflow. The significance of the infrastructure plays a vital role in the promotion of foreign direct investment inflow. The research data extensively explore the query of how the nonexistence of infrastructure can affect foreign direct investment inflow along with the different results of foreign direct investment in the host nation. Though the literature review has given little concentration to examine the role of FDI in improving the obtainability and quality of infrastructure in developing nations' economies. According to Pradhan et al. [8] illustrated that the foreign organizations carried progressive technology and skills to the host nation herewith encouraged new technological dissemination in the nation along with investment. FDI inflow also facilitates home organizations with an unintended opportunity to learn from the foreign firms by studying and permeating an intelligence of plenteous needed competition [9]: which develops a cumulative output of the ant nation economy. Foreign direct investment plays a significant role in economic growth [10], the positive impact of FDI inflow is not only inadequate to the transfer of better technology, in circumstance, it also needs any nation to develop the quality infrastructure [11]. As a developing nation economy like Indian have enough resources but do not advance technology to effective utilization of the resources, to improve the infrastructure facilities in India, advanced technology is required, it is required the support of overseas capital to improve their infrastructure facilities. Foreign companies cooperate in R&D in enhancing innovative technology and development of any nation, specifically in infrastructure development to bond up with various markets in the different nations. The literature review broadly examined the various determinants factors of FDI like population, political stability and institutional quality etc. [12]. As this critical point lacks in review, this paper aims to examine the causal two functional relationships between total FDI and total infrastructure and enhance the literature review on this vital singularity. Furthermore, the literature discloses that prevailing research articles on the subject matter hurt from numerous data limitations [13]. The original paper on infrastructure focuses on variables representative of infrastructure for a large nation sample during 1990–2018 but it does not formulate an index of cumulative infrastructure. Likewise, extensively the review on infrastructure projects in different sectors depend on a very inadequate description of infrastructure while examining its stimulus on different economic indicators are investment, trade, and growth. Gnangnon (2018) assessed the impact of the telecommunication infrastructure on economic growth in a developing nation like India. Chakraborty and Nunnenkamp [14] uses ITC (international telephone circuits), the inclusive road infrastructure length and the number of airways as a proxy for the infrastructure development to examine the relationship between public infrastructure and foreign capital. Hall et al. [15] investigated broader insight and apprehension of the various infrastructure components to assess the association between transportation cost and infrastructure growth.

As for the given information limitations, this research paper employs a recently established inclusive using global infrastructure index 2020 which comprehends numerous infrastructure extents for India to overcome statistics limitations in secondary information. Predominantly the global infrastructure index 2020 is grounded on an annual wide-ranging of minimum 15 indicators datasheet of the obtainability and quality of infrastructure during 1995–2018 formulated by Khan et al. [16, 17]. In this research paper, the following infrastructure parameters (like power sector, construction, transportation, telecommunication, health, finance and energy) are used. UCM (Unobserved Components Model) is employed expedient infrastructure from the sub-parameters of infrastructure development. Additionally, the paper highlights some important points According to the Reserve Bank of India, infrastructure covers the following sectors also Power, Telecommunications, Railways, Roads including bridges, Seaport and airport, Industrial parks, Urban infrastructure, Mining, exploration and refining, and Cold storage and cold room facility, including for farm level pre-cooling for the preservation or storage of agricultural and allied produce, marine products and meat.
